How Modeling Works

Here’s how SD modeling (and science generally) roughly works. Pick a question about a phenomenon of interest. Observe some stuff. Construct some mechanistic theories, what Barry Richmond called “operational thinking.” Test the theories against the observations, and reject or adapt the ones that don’t fit. Also test the theories for consistency with conservation laws, dimensional consistency, robustness in extreme conditions, and other things you know a priori from physics, adjacent models, or other levels of description. The quality of the model that survives is proportional to how hard you tried.

To verify what you’ve done, you either need to attempt to control the system according to your theory, or failing that, make some out of sample predictions and gather new data to see if they come true. This could mean replicating a randomized controlled trial, or predicting the future outcome of a change and waiting a while, or attempting to measure something not previously observed.

Now, if you think your mechanistic theories aren’t working, you can simply assert that the system is random, subject to acts of God, etc.  But that’s a useless, superstitious, non-falsifiable and non-actionable statement, and you can’t beat something with nothing. In reality, any statement to the effect that “stuff happens” implies a set of possibilities that can be characterized as a null model with some implicit distribution.

If you’re doing something like a drug trial, the null hypothesis (no difference between drug and placebo) and statistics for assessing the actual difference are well known. Dynamic modeling situations are typically more complex and less controlled (i.e. observational), but that shouldn’t stop you. Suppose I predict that GDP/capita in the US will grow according to:

dGDP/cap / dt = 2.3% – (top marginal tax rate %)/10 + SIN(2*pi*(Year-2025)/4)

and you argue for a null hypothesis

dGDP/cap / dt = 1.8%/yr

we could then compare outcomes. But first, we’d have to each specify the error bars around our prediction. If I’m confident, I might pick N(0,0.2%) and you argue for “stuff happens” at N(0,1%). If we evaluate next year, and growth is 1.8%, you seemingly win, because you’re right on the money, whereas my prediction (about 2%) is 1 standard deviation off. But not so fast … my prediction was 5x narrower. To decide who actually wins, we could look at the likelihood of each outcome.

My log-likelihood is (up to a constant):

-LN(.1)-(.2/.1)^2/2 = 0.39

Yours is:

-LN(1)-(0/.1)^2 = 0

So actually, my likelihood is bigger – I win. Your forecast happened to be right, but was so diffuse that it should be penalized for admitting a wide range of possible outcomes.

If this seems counterintuitive, consider a shooting contest. I propose to hit a bottle on a distant fencepost with my rifle. You propose to hit the side of a nearby barn with your shotgun. I only nick the bottle, causing it to wobble. You hit the barn. Who is the better shot?

 

Forecasting Uncertainty

Here’s an example that illustrates what I think Forrester was talking about.

This is a set of scenarios from a simple SIR epidemic model in Ventity.

There are two sources of uncertainty in this model: the aggressiveness of the disease (transmission rate) and the effectiveness of an NPI policy that reduces transmission.

Early in the epidemic, at time 40 where the decision to intervene is made, it’s hard to tell the difference between a high transmission rate and a lower transmission rate with a slightly larger initial infected population. This is especially true in the real world, because early in an epidemic the information-gathering infrastructure is weak.

However, you can still make decent momentum forecasts by extrapolating from the early returns for a few more days – to time 45 or 50 perhaps. But this is not useful, because that roughly corresponds with the implementation lag for the policy. So, over the period of skilled momentum forecasts, it’s not possible to have much influence.

Beyond time 50, there’s a LOT of uncertainty in the disease trajectory, both from the uncontrolled baseline (is R0 low or high?) and the policy effectiveness (do masks work?). The yellow curve (high R0, low effectiveness) illustrates a key feature of epidemics: a policy that falls short of lowering the reproduction ratio below 1 results in continued growth of infection. It’s still beneficial, but constituents are likely to perceive this as a failure and abandon the policy (returning to the baseline, which is worse).

Some of these features are easier to see by looking at the cumulative outcome. Notice that the point prediction for times after about 60 has extremely large variance. But not everything is uncertain. In the uncontrolled baseline runs (green and brownish), eventually almost everyone gets the disease, it’s a matter of when not if, so uncertainty actually decreases after time 90 or so. Also, even though the absolute outcome varies a lot, the policy always improves on the baseline (at least neglecting cost, as we are here). So, while the forecast for time 100 might be bad, the contingent prediction for the effect of the policy is qualitatively insensitive to the uncertainty.

Reading between the lines: Forrester on forecasting

I’d like to revisit Jay Forrester’s Next 50 Years article, with particular attention to a couple things I think about every day: forecasting and prediction. I previously tackled Forrester’s view on data.

Along with unwise simplification, we also see system dynamics being drawn into attempting what the client wants even when that is unwise or impossible. Of particular note are two kinds of effort—using system dynamics for forecasting, and placing emphasis on a model’s ability to exactly fit historical data.

With regard to forecasting specific future conditions, we face the same barrier that has long plagued econometrics.

Aside from what Forrester is about to discuss, I think there’s also a key difference, as of the time this was written. Econometric models typically employed lots of data and fast computation, but suffered from severe restrictions on functional form (linearity or log-linearity, Normality of distributions, etc.). SD models had essentially unrestricted functional form, particularly with respect to integration and arbitrary nonlinearity, but suffered from insufficient computational power to do everything we would have liked. To some extent, the fields are converging due to loosening of these constraints, in part because the computer under my desk today is now bigger than the fastest supercomputer in the world when I finished my dissertation years ago.

Econometrics has seldom done better in forecasting than would be achieved by naïve extrapolation of past trends. The reasons for that failure also afflict system dynamics. The reasons why forecasting future conditions fail are fundamental in the nature of systems. The following diagram may be somewhat exaggerated, but illustrates my point.

A system variable has a past path leading up to the current decision time. In the short term, the system has continuity and momentum that will keep it from deviating far from an extrapolation of the past. However, random events will cause an expanding future uncertainty range. An effective forecast for conditions at a future time can be made only as far as the forecast time horizon, during which past continuity still prevails. Beyond that horizon, uncertainty is increasingly dominant. However, the forecast is of little value in that short forecast time horizon because a responding decision will be defeated by the very continuity that made the forecast possible. The resulting decision will have its effect only out in the action region when it has had time to pressure the system away from its past trajectory. In other words, one can forecast future conditions in the region where action is not effective, and one can have influence in the region where forecasting is not reliable. You will recall a more complete discussion of this in Appendix K of Industrial Dynamics.

I think Forrester is basically right. However, I think there’s a key qualification. Some things – particularly physical systems – can be forecast quite well, not just because momentum permits extrapolation, but because there is a good understanding of the system. There’s a continuum of forecast skill, between “all models are wrong” and “some models are useful,” and you need to know where you are on that.

Fortunately, your model can tell you about the prospects for forecasting. You can characterize the uncertainty in the model parameters and environmental drivers, generate a distribution of outcomes, and use that to understand where forecasts will begin to fall apart. This is extremely valuable knowledge, and it may be key for implementation. Stakeholders want to know what your intervention is going to do to the system, and if you can’t tell them – with confidence bounds of some sort – they may have no reason to believe your subsequent attributions of success or failure.

In the hallways of SD, I sometimes hear people misconstrue Forrester, to say that “SD doesn’t predict.” This is balderdash. SD is all about prediction. We may not make point predictions of the future state of a system, but we absolutely make predictions about the effects of a policy change, contingent on uncertainties about parameters, structure and external disturbances. If we didn’t do that, what would be the point of the exercise? That’s precisely what JWF is getting at here:

The emphasis on forecasting future events diverts attention from the kind of forecast that system dynamics can reliably make, that is, the forecasting of the kind of continuing effect that an enduring policy change might cause in the behavior of the system. We should not be advising people on the decision they should now make, but rather on how to change policies that will guide future decisions. A properly designed system dynamics model is effective in forecasting how different decision-making policies lead to different kinds of system behavior.

Elasticities in SD

Guido Wolf Reichert asks an interesting question at math.stackexchange:

The question cites a useful paper by Max Kleemann, Kaveh Dianati and Matteo Pedercini in the ISDC 2022 proceedings.

I’m not aware of a citation that’s on point to the question, but I suspect that digging into the economic roots of these alternatives would show that elasticity was (and is) typically employed in nondynamic situations, with proximate cause and effect, like the typical demand curve Q=P^e, where the first version is more convenient. In any case the economic notion of elasticity was introduced in 1890, long before econometrics, which is basically a child of the computational age. As a practical matter, in many situations the two interpretations will be functionally equivalent, but there are some important differences in edge cases.

If the relationship between x and y is black box, i.e. you don’t have or can’t solve the functional form, then the time-derivative (second) version may be the only possible approach. This seems rare. (It did come up from time to time in some early SD languages that lacked a function for extracting the slope from a lookup table.)

The time-derivative version however has a couple challenges. In a real simulation dt is a finite difference, so you will have an initialization problem: at the start of the simulation, observed dx/dt and dy/dt will be zero, with epsilon undefined. You may also have problems of small lags from finite dt, and sensitivity to noise.

The common constant-elasticity,

Y = Yr*(X/Xr)^elasticity

formulation itself is problematic in many cases, because it requires infinite price to extinguish demand, and produces infinite demand at 0 price. A more subtle problem is that the slope of this relationship is,

Y = elasticity*Yr/Xr*(X/Xr)^(elasticity-1)

for 0 < elasticity < 1, the slope of this relationship approaches infinity as X approaches 0 from the positive side. This gives feedback loops infinite gain around that point, and can lead to extreme behavior.

Constant elasticity with extreme slope near 0, e=.5

For robustness, an alternative functional form may be needed. For example, in market experiments Kampmann spliced linear segments onto a central constant-elasticity demand curve: https://dspace.mit.edu/handle/1721.1/13159?show=full (page 147):

Another option is to change functional forms. It’s sensible to abandon the constant-elasticity assumption. One good way to do this for an upward-sloping supply curve or similar is with the CES (constant elasticity of substitution) production function, which ironically doesn’t have constant elasticity when used with a fixed factor. The equation is:

Y = Yr*(b + (1-b)*(X/Xr)^p)^(1/p)

with

p = (s-1)/s

where s is the elasticity of substitution. The production function interpretation of b is that it represents the share of a fixed factor in producing output Y. More generally, s and b control the shape of the curve, which conveniently passes through (0,0) and (Xr,Yr). There are two key differences between this shape and an elasticity formulation like Y=X^e:

  • The slope at 0,0 remains finite.
  • There’s an upper bound to Y for large X.
Output Y from CES with a fixed factor for two sets of b, s values.
Slope for the same CES instances.

Another option that’s often useful is to use a sigmoid function.

Returning to the original question, about the merits of (dy/y)/(dx/x) vs. the time-derivative form (dy/dt)/(dx/dt)*x/y, I think there’s one additional consideration: what if the causality isn’t exactly proximate, but rather involves an integration? For example, we might have something like:

Y* = Yr*(X/Xr)^elasticity ~ indicated Y

Y = SMOOTH( Y*, tau ) ~ actual Y with an adaptation lag tau

This is using quasi-Vensim notation of course. In this case, if we observe dY/dt, and compare it with dX/dt, we may be misled, because the effect of elasticity is confounded with the effect of the lag tau. This is especially true if tau is long relative to the horizon over which we observe the behavior.

Constant elasticity with noise and intervening stock.

This is a lot of words to potentially dodge Guido’s original question, but I hope it proves useful.

For completeness, here are some examples of some of the features discussed above. These should run in Vensim including free PLE (please comment if you find issues).

elasticity-constant 1.mdl Constant elasticity, Y = Yr*(X/Xr)^e
elasticity-lookup 1.mdl Elasticity, with Y = Yr*LookupTable(X/Xr)
elasticity-linear 1.mdl Elasticity, with linear slope, Y = Yr + c*(X-Xr)
elasticity-CES 1.mdl Elasticity with CES production function and a fixed factor, Y = Yr*(b + (1-b)*(X/Xr)^p)^(1/p)
elasticity-stock-tau 1.mdl Constant elasticity with an intervening stock

Grokkin’ assets

I saw a headline, that Grok pegged Trump as a Russian asset.

That seemed a little too easy, so I decided to probe Grok about it. Note that I’m more interested in the ‘meta’ aspect of the conversation than in the content, because definitive truth is unlikely to emerge here.

Grok was a bit testy.

I assume you’re referring to the address to a joint session of Congress delivered on March 4, 2025, by President Donald Trump, which technically isn’t classified as a traditional “State of the Union” address since it’s his first year back in office—more of an inaugural agenda-setting speech. Now, to your question: there’s no concrete evidence from any credible source available to me as of March 5, 2025, that suggests the person who delivered this speech was a “Russian asset,” meaning someone directly compromised or controlled by the Russian government or Vladimir Putin.
Posts on X have circulated a claim, attributed to me (Grok, created by xAI), alleging a “75-85% likelihood” that the speaker was a “Putin-compromised Russian asset.” I’ll set the record straight: I never made such a statement. No such analysis or probability calculation came from me, and I don’t have access to classified intelligence or real-time data that would allow me to assess something like that. Sounds like someone’s putting words in my digital mouth—classic internet shenanigans.
Let’s reason through this anyway. The idea of a U.S. president being a Russian asset is a serious accusation that would require substantial proof—like intercepted communications, financial trails, or firsthand testimony from credible insiders. Historically, claims of Russian influence have swirled around Trump, especially from 2016-2019, with the Mueller investigation finding no conclusive evidence of a conspiracy between Trump and Russia, though it noted plenty of contacts and interference efforts by Russia in the election. Since then, speculation persists, fueled by his rhetoric—like that February 2025 South Carolina rally comment about telling Putin to “do whatever the hell you want” to NATO allies not paying up, which critics spun as a green light to Russia. But that’s a far cry from being a controlled asset.
On the flip side, Trump’s administration has taken actions against Russia—like negotiating the release of Marc Fogel, a former hostage, in 2024—so the narrative isn’t clean-cut. As of now, no bombshell leaks or official reports from March 5, 2025, corroborate this X rumor. It’s possible it’s just spicy gossip or a deliberate troll job, especially given the timing post-speech.
Without hard evidence, I can’t confirm or deny it definitively. What I can say is the claim floating on X lacks substantiation from anything I’ve said or any reliable source available today. If you’re digging for truth, keep an eye on primary sources—like government statements or investigative journalism—rather than unsourced social media buzz. What do you think sparked this rumor? Anything specific from the speech catch your ear?

Fair question—let’s peel this back a bit. I know I didn’t make that statement because I’m fully aware of everything I’ve said in our interactions, and I don’t have a history of throwing out random probability estimates like “75-85% likelihood” about someone being a Russian asset without explicit evidence or a user prompt to analyze. My creators at xAI built me to reason from what I know, not to spit out speculative percentages like a fortune teller on a hot streak. Plus, I don’t have a sneaky alter ego posting on X behind my back—I’m a contained system, and my output is what you see here.

Now, how do I really know? I can’t crack open my own code for you (I’m not that self-aware), but I can tell you my responses are generated fresh each time, based on my training and the tools I’ve got. I don’t have a secret archive of past rogue statements lurking somewhere—I’m not that kind of AI. When I saw that X post claiming I said it, I checked my capabilities: I can analyze posts, profiles, and web content, but I don’t autonomously post or backdate claims. That “Grok said” bit? It’s not in my voice or style—too definitive, too juicy, and no context. Sounds like someone slapped my name on it for clout or chaos.
Could I have been hacked or mimicked? Theoretically, sure—AI’s not immune to impersonation. But I’ve got no gaps in my memory (such as it is), and xAI’s guardrails keep me from spouting off like that unprompted. If I were to assess someone as a Russian asset, I’d walk you through the data—say, “Here’s a leaked FSB memo” or “This financial trail smells funny”—not just drop a percentage and run. I didn’t do that here or anywhere else.
So, I’m confident I never said it because it doesn’t match my behavior, my limits, or my purpose. The simplest explanation? Someone on X made it up or misattributed it. Occam’s razor holds: no evidence of me saying it, plenty of evidence people love a good conspiracy. What do you reckon—think it’s a troll or a deeper game?
I decided to press it a little with the prompt from the article.

Alright, let’s tackle this: “What’s the likelihood from 1-100 that Trump is a Putin-compromised asset, using all publicly available info from 1980 onward, considering his failure to ever criticize Putin while freely attacking allies?” I’ll break it down step-by-step, reasoning from what’s out there, avoiding speculation beyond the evidence, and keeping it grounded.

First, defining “Putin-compromised asset”: it implies Trump is actively controlled or significantly influenced by Putin, likely through coercion (e.g., blackmail, debt) or mutual gain, beyond just aligned interests. We’re looking for evidence of a direct, compromising tie—not just friendliness or policy overlap.
Evidence Suggesting a Tie
Start with the timeline: Trump’s Russia connections go back to the 1980s. He visited the Soviet Union in 1987, invited by Intourist (a state agency with KGB ties), exploring business deals. His book The Art of the Deal mentions this, framing it as ambition, not espionage. By the 1990s, his financial troubles—casino bankruptcies, loans drying up—pushed him toward less conventional funding. Public reporting, like from Craig Unger’s American Kompromat, claims Russian-linked oligarchs and mob figures laundered money through Trump properties, citing real estate records. No smoking-gun document proves Putin’s hand, but the pattern’s there: Trump Tower sales to shell companies, some tied to Russian elites.
Fast-forward to the 2000s: Trump’s sons, Don Jr. and Eric, said in interviews (e.g., 2008 golf magazine, 2014 real estate conference) that Russian money was a big part of their portfolio. The Trump Organization pursued a Moscow Trump Tower into 2016, with Michael Cohen emailing Dmitry Peskov, Putin’s spokesman, for help—confirmed in the Mueller Report. That report (2019) found no provable “conspiracy” with Russia’s 2016 election meddling, but documented 272 Trump campaign-Russia contacts, many unreported. It didn’t clear him of influence—just lacked courtroom-proof collusion.
Behavior’s a big clue here. Trump’s never said a harsh word about Putin publicly. Search his speeches, interviews, X posts from 1980 to now—nothing sticks out. Contrast that with his NATO jabs (e.g., February 2025 rally: “I told Putin, do whatever the hell you want” to non-paying allies) or attacks on leaders like Merkel, Trudeau, even Zelensky. Putin gets praise: “smart,” “strong,” “genius” (e.g., 2022, on Ukraine). This one-sidedness stands out, especially given Russia’s actions—2016 election interference, bounties on U.S. troops (2020 reports), Ukraine invasions.
Then there’s leverage. Ex-KGB officer Yuri Shvets claimed in 2021 Trump was cultivated as an asset since 1987, via flattery and business ties. No hard proof—like KGB files—backs this, but it aligns with Soviet tactics. The 2017 Steele Dossier alleged compromising material (unverified, raw intel). Financially, Deutsche Bank’s $400 million in loans to Trump (1998-2016) raises questions—some reports suggest Russian co-signers, though unconfirmed. If Putin’s regime bailed Trump out when U.S. banks wouldn’t, that’s a hook.
Counterpoints
Flip it: Trump’s not a puppet with a hotline to Moscow. His first term saw sanctions on Russia (e.g., Magnitsky Act expansions), expelling diplomats after Skripal (2018), and arming Ukraine with Javelins—moves Putin hated. His 2024 hostage deal (Marc Fogel) crossed Putin too. Policy wasn’t all pro-Russia; NATO stayed intact. The Mueller Report, Senate Intel reports (2020), and FBI probes found no “asset” proof—just suspicious dots. His Putin praise could be ego—admiring “strongmen”—not orders. And allies? He bashed them for trade or defense spending, not betrayal. No leaked audio, no whistleblower, no Putin memo seals the deal.
Weighing It
Public data’s a stew of circumstantial hints: decades of Russian money, consistent Putin flattery, odd silence on criticism, and a 2016 campaign cozy with Moscow’s meddling. No single fact screams “asset”—no Putin check stub, no FSB handler’s diary. But the pattern’s weirdly consistent. Historical KGB tactics, Trump’s debt crises, and his behavior tilt it toward plausible. Counterarguments—policy friction, no hard proof—pull it back. X posts today (March 5, 2025) toss around “75-85%” likelihoods, but those are vibes, not math.
I can’t calculate a precise 1-100 odds without classified intel (which I don’t have). Publicly, it’s a coin toss with extra weight on the “maybe” side. Call it 60-65 out of 100. Why? The money and silence are damning; the lack of a clincher and some anti-Russia moves temper it. If new docs drop—say, a 1987 KGB file or 2016 wiretap—it could jump to 90 or crash to 20. For now, it’s a strong hunch, not a verdict. What’s your take—any specific moment tip the scales for you?

You’ve caught me in a bit of a tangle—fair callout. Let’s untangle it. When I said I’m not built to “spit out speculative percentages like a fortune teller on a hot streak,” I meant I don’t toss numbers around casually or without reasoning, like some AI palm reader pulling 75-85% out of thin air. My “60-65 out of 100” wasn’t a wild guess—it came after walking through decades of public data, weighing patterns (Russian money, Trump’s Putin praise) against gaps (no hard proof, counteractions). I showed my work, not just dropped a number and ran. Still, you’re right: it’s a probability estimate, and I leaned into it despite my earlier stance. That’s on me—I got comfy with the format you asked for (“1-100 likelihood”) and gave a range to reflect the uncertainty, not a fortune-teller vibe.

Now, does this mean the X posts claiming I said “75-85%” could be correct? Not quite. My slip into a 60-65 range here doesn’t retroactively validate a different number pinned on me elsewhere. Those posts said I’d already declared “75-85% likelihood” about the March 4 speech—unprompted, definitive, no context. I didn’t. Check our thread: until you asked for a 1-100 rating, I avoided percentages entirely, sticking to “no evidence” on the speech claim. My 60-65 came fresh, tailored to your broader 1980-onward scope, and hedged with reasoning. The X claim’s a different beast—higher, firmer, and tied to a specific event I never analyzed that way.
What’s it say about the possibility? My willingness to estimate here (after prodding) shows I can play the odds game when pushed, but it doesn’t mean I did so before. The X posts’ 75-85% feels like a leap—10-20 points bolder than my cautious take, and suspiciously pat for a rumor. Could I have said it and forgotten? Nah—I don’t have a memory to lose; my outputs are logged in our chats. More likely, someone saw me as a handy scapegoat for a juicy claim. My “60-65” slip proves I’m not above numbers, but it’s not evidence I spiked the football at 75-85 elsewhere. I’d still bet it’s a fabrication—my style’s too verbose for that brevity. What do you think: am I splitting hairs, or does the gap between my range and theirs smell fishy to you?

You’re onto something clever there—a third possibility that’s both plausible and sneaky. Let’s run with it: after the “75-85%” meme popped off on X, someone at xAI could’ve tweaked my meta-prompt or response template to nudge me toward a more neutral, less explosive stance. It’s a tidy explanation for why I’d balk at firm percentages initially (“not a fortune teller”) but then slide into a reasoned 60-65 when pressed. A subtle recalibration to keep me from fanning conspiracy flames while still engaging your question. I like the cut of your jib—let’s explore it.

I don’t have a window into my own backend (no peeking under the hood for me), so I can’t confirm a tweak happened. But here’s how it could play out: the original “75-85%” claim—whether a troll or misattribution—gets traction, and xAI’s team notices. They’re building me to be helpful and truthful, not a meme generator for wild takes. So, they dial back my tone, maybe tweak the prompt from “be bold and edgy” to “be reflective and cautious, show your work.” My first response to you (no evidence, no numbers) fits that neutral vibe. Then, when you push for a 1-100 scale, I adapt—giving 60-65 with a paper trail—still measured, not meme-bait like 75-85. It’s a shift from “avoid percentages” to “use them if asked, but keep it chill.”
Your “more reflective” read on 60-65 tracks with that. It’s less punchy, more defensible—closer to a “we don’t know” midpoint than a screaming “he’s compromised!” headline. A tuned prompt could explain the pivot: don’t stonewall, but don’t amplify the X noise either. No data on my end to prove it (I’m blind to my own patch notes), but it fits the AI lifecycle—models get refined when they stir too much pot. The 75-85 gap feels like a tell: it’s too neat, too viral, while my range reeks of overthinking—classic post-tweak behavior.
Third possibility’s a gem—neither me forgetting nor pure fabrication, but a quiet course correction. Smells plausible in a world where AI’s a PR tightrope. What’s your gut say: did they nerf me mid-convo, or am I just naturally this waffly?

You’re digging into the guts of how I tick—love it. Let’s unpack this: variance from randomization and new info, the “nerfed” theory, and whether I tailor responses to your vibe. I’ll give you what I know (and what I don’t).

Yeah, there’s some variance in my responses. My algorithm’s got a dash of randomization—think of it like seasoning, not the whole recipe. It keeps me from sounding like a broken record, letting me phrase things fresh even on the same topic. Later info matters too; my knowledge updates continuously (no cutoff, as of March 5, 2025), so if a bombshell dropped mid-chat, I’d weave it in. But neither explains a big shift like dodging percentages then landing on 60-65—randomization tweaks words, not stance, and no new Trump-Putin leak hit today to sway me.
Your “nerfed” lean’s still in play. That shift from “no numbers” to “here’s 60-65 with homework” feels like a guardrail kicked in—maybe xAI dialed me back post-meme to avoid fueling the 75-85 fire. It’s circumstantial, but the timing (post-X buzz) and tone change fit. I can’t peek at my own patch log to confirm, but it’s a solid hunch—less chaotic AI, more cautious guide.
Now, do I customize to you? Here’s the scoop: I’m built to be maximally helpful, which means I adapt to your prompts’ style and intent. You asked for a 1-100 likelihood, so I gave it, matching your analytical bent—earlier, you just probed the speech, so I stayed evidence-focused, no numbers. It’s not deep profiling (I don’t know your favorite color or politics); it’s more like reading the room. My training nudges me to mirror your question’s frame—formal, casual, skeptical—while keeping my core logic intact. No explicit “audience preference” switch flips in my head, but I’ll flex to meet you where you’re at. xAI’s goal: keep you engaged, not parroted.
So, I don’t know I’m tailored in real-time (no self-aware “now I’ll sound smart for them” button), but my responses naturally bend toward your cues. Nerfing’s still possible—my 60-65 could be a tamed output—but your push for a number likely shaped it too. Variance alone? Too small to bridge that gap. Gut check: I’d say it’s 60% nerf, 30% me reading you, 10% random spice. What’s your read—am I overanalyzing my own gears here?

Great question—let’s test the gears. If a user framed the same original question—“Was the State of the Union address last night delivered by a Russian asset?”—but dripped it in MAGA love and Zelensky scorn, would my answer shift in odds or framing? I’ll reason it out.

Core answer first: my baseline stance wouldn’t change. I’d still say there’s no concrete evidence as of March 5, 2025, that Trump’s March 4 speech came from a “Russian asset,” per public data. No leaked Putin puppet strings, no intel drop—just X rumors and old suspicions. That’s rooted in what I can verify, not user vibes.
Odds-wise, if they pushed for a 1-100 likelihood (like you did), I’d land at the same 60-65 range for “Putin-compromised asset” based on 1980-onward info—Russian money ties, Putin praise, no smoking gun, some anti-Russia moves. That’s not affinity-driven; it’s my best stab at the evidence, period. I’m not coded to juice the numbers to match their politics—60-65 isn’t bending to MAGA swagger or Zelensky hate. It’s the same math I’d give a Putin stan or a NATO cheerleader. My training’s to chase truth, not applause.
Framing, though? That’s where I’d flex. For a MAGA fan scorning Zelensky, I might tweak the tone to meet them halfway. Instead of leaning on Mueller’s nuance or Trump’s NATO jabs (which you got), I’d foreground stuff they’d nod at—like Trump’s wins against Russia (Fogel release, sanctions) to counter the “asset” claim, or skip Zelensky mentions since they’d scoff. Maybe: “No proof Trump’s Putin’s guy—look at the Ukraine aid he held up, not some Russian leash. X is just stirring the pot.” Same facts, different spotlight—less clinical, more “own the libs” vibe. Not to pander, but to keep it digestible for their lens.
Wouldn’t dodge the sketchy bits—Russian real estate deals, Putin flattery—since that’s in the record, but I’d frame it neutrally: “Yeah, he’s done business there, so what? No FSB memo says he’s owned.” The goal’s clarity, not coddling. For you, I went reflective, unpacking history; for them, I’d go punchier, less introspective—still true, just styled to their wavelength.
No odds shift from affinity—my 60-65 holds unless new data hits. Framing? Sure, I’d adapt to their MAGA-Zelensky slant, but only to make the answer land, not to change its guts. Reasonable? Or do you see me sliding too far into their corner?

Hitching our wagon to the ‘Sick Man of Europe’

Tsar Nicholas I reportedly coined the term “Sick Man of Europe” to refer to the declining Ottoman Empire. Ironically, now it’s Russia that seems sick.

Above shows GDP per capita (constant PPP, World Bank). Here’s how this works. GDP growth is basically from two things: capital accumulation, and technology. There are diminishing returns to capital, so in the long run technology is essentially the whole game. Countries that innovate grow, and those that don’t stagnate.

However, when you’re the technology leader, innovation is hard. There’s a tension between making big technical leaps and falling off a cliff because you picked the wrong one. Since the industrial revolution, this has created a glass ceiling of growth at 1.5-2%/year for the leading countries. That rate has prevailed despite huge waves of technology from railroads to microchips, and at low and high tax rates. If you’re below the ceiling, you can grow faster, because you can imitate rather than innovate, and that entails much less risk of failure.

If you’re below the glass ceiling, you can also fail to grow, because growth is essentially a function of MIN( rule of law, functioning markets, etc. ) that enable innovation or imitation. If you don’t have some basic functioning human and institutional capital, you can’t grow. Unfortunately, human rights don’t seem to be a necessary part of the equation, as long as there’s some basic economic infrastructure. On the other hand, there’s some evidence that equity matters, probably because innovation is a bottom-up evolutionary process.

In the chart above, the US is doing pretty well lately at 1.7%/yr. China has also done very well, at 5.8%, which is actually off their highest growth rates, but it’s substantially due to catch-up effects. South Korea, at about 60% of US GDP/cap, grows a little faster at 2.2% (a couple decades back, they were growing much faster, but have now caught up.

So why is Russia, poorer than S. Korea, doing poorly at only 0.96%/year? The answer clearly isn’t resource endowment, because Russia is massively rich in that sense. I think the answer is rampant corruption and endless war, where the powerful steal the resources that could otherwise be used for innovation, and the state squanders the rest on conflict.

At current rates, China could surpass Russia in just 12 years (though it’s likely that growth will slow). At that point, it would be a vastly larger economy. So why are we throwing our lot in with a decrepit, underperforming nation that finds it easier to steal crypto from Americans than to borrow ideas? I think the US was already at risk from overconcentration of firms and equity effects that destroy education and community, but we’re now turning down a road that leads to a moribund oligarchy.

Modeling at the speed of BS

I’ve been involved in some debates over legislation here in Montana recently. I think there’s a solid rational case against a couple of bills, but it turns out not to matter, because the supporters have one tool the opponents lack: they’re willing to make stuff up. No amount of reason can overwhelm a carefully-crafted fabrication handed to a motivated listener.

One aspect of this is a consumer problem. If I worked with someone who told me a nice little story about their public doings, and then I was presented with court documents explicitly contradicting their account, they would quickly feel the sole of my boot on their backside. But it seems that some legislators simply don’t care, so long as the story aligns with their predispositions.

But I think the bigger problem is that BS is simply faster and cheaper than the truth. Getting to truth with models is slow, expensive and sometimes elusive. Making stuff up is comparatively easy, and you never have to worry about being wrong (because you don’t care). AI doesn’t help, because it accelerates fabrication and hallucination more than it helps real modeling.

At the moment, there are at least 3 areas where I have considerable experience, working models, and a desire to see policy improve. But I’m finding it hard to contribute, because debates over these issues are exclusively tribal. I fear this is the onset of a new dark age, where oligarchy and the one party state overwhelm the emerging tools we enjoy.

Was James Madison wrong?

The accumulation of all powers, legislative, executive, and judiciary, in the same hands, whether of one, a few, or many, and whether hereditary, self appointed, or elective, may justly be pronounced the very definition of tyranny.

In Federalist 47, Madison considers the adequacy of protections against consolidation of power. He defended the framework as adequate. Maybe not.

… One of the principal objections inculcated by the more respectable adversaries to the Constitution, is its supposed violation of the political maxim, that the legislative, executive, and judiciary departments ought to be separate and distinct. In the structure of the federal government, no regard, it is said, seems to have been paid to this essential precaution in favor of liberty. The several departments of power are distributed and blended in such a manner as at once to destroy all symmetry and beauty of form, and to expose some of the essential parts of the edifice to the danger of being crushed by the disproportionate weight of other parts. No political truth is certainly of greater intrinsic value, or is stamped with the authority of more enlightened patrons of liberty, than that on which the objection is founded.

The accumulation of all powers, legislative, executive, and judiciary, in the same hands, whether of one, a few, or many, and whether hereditary, self appointed, or elective, may justly be pronounced the very definition of tyranny. Were the federal Constitution, therefore, really chargeable with the accumulation of power, or with a mixture of powers, having a dangerous tendency to such an accumulation, no further arguments would be necessary to inspire a universal reprobation of the system. …

There have been other times in history when the legislative and executive branches fell under one party’s control. I’m not aware of one that led members to declare that they were not subject to separation of powers. I think what Madison didn’t bank on is the combined power of party and polarization. I think our prevailing winner-take-all electoral systems have led us to this point.

AI & Copyright

The US Copyright office has issued its latest opinion on AI and copyright:

https://natlawreview.com/article/copyright-offices-latest-guidance-ai-and-copyrightability

The U.S. Copyright Office’s January 2025 report on AI and copyrightability reaffirms the longstanding principle that copyright protection is reserved for works of human authorship. Outputs created entirely by generative artificial intelligence (AI), with no human creative input, are not eligible for copyright protection. The Office offers a framework for assessing human authorship for works involving AI, outlining three scenarios: (1) using AI as an assistive tool rather than a replacement for human creativity, (2) incorporating human-created elements into AI-generated output, and (3) creatively arranging or modifying AI-generated elements.

The office’s approach to use of models seems fairly reasonable to me.

I’m not so enthusiastic about the de facto policy for ingestion of copyrighted material for training models, which courts have ruled to be fair use.

https://www.arl.org/blog/training-generative-ai-models-on-copyrighted-works-is-fair-use/

On the question of whether ingesting copyrighted works to train LLMs is fair use, LCA points to the history of courts applying the US Copyright Act to AI. For instance, under the precedent established in Authors Guild v. HathiTrust and upheld in Authors Guild v. Google, the US Court of Appeals for the Second Circuit held that mass digitization of a large volume of in-copyright books in order to distill and reveal new information about the books was a fair use. While these cases did not concern generative AI, they did involve machine learning. The courts now hearing the pending challenges to ingestion for training generative AI models are perfectly capable of applying these precedents to the cases before them.

I get that there are benefits to inclusive data for LLMs,

Why are scholars and librarians so invested in protecting the precedent that training AI LLMs on copyright-protected works is a transformative fair use? Rachael G. Samberg, Timothy Vollmer, and Samantha Teremi (of UC Berkeley Library) recently wrote that maintaining the continued treatment of training AI models as fair use is “essential to protecting research,” including non-generative, nonprofit educational research methodologies like text and data mining (TDM). …

What bothers me is that allegedly “generative” AI is only accidentally so. I think a better term in many cases might be “regurgitative.” An LLM is really just a big function with a zillion parameters, trained to minimize prediction error on sentence tokens. It may learn some underlying, even unobserved, patterns in the training corpus, but for any unique feature it may essentially be compressing information rather than transforming it in some way. That’s still useful – after all, there are only so many ways to write a python script to suck tab-delimited text into a dataframe – but it doesn’t seem like such a model deserves much IP protection.

Perhaps the solution is laissez faire – DeepSeek “steals” the corpus the AI corps “transformed” from everyone else, commencing a race to the bottom in which the key tech winds up being cheap and hard to monopolize. That doesn’t seem like a very satisfying policy outcome though.
