How can I tell whether an expert is feeding me his best attempt at truth optimization vs feeding me BS (in the David Pinsof evolutionary psychology sense)?
The simplest way is to stop listening to what the expert says he is doing and instead look at what incentives he is under and what constraints he accepts.
Pinsof’s basic point is that most public speech is alliance management, not truth optimization. So the question becomes whether the speaker is constrained by reality or by coalition loyalty.
A few signals help.
Look at skin in the game.
If someone’s claims can be falsified by events that affect their reputation or livelihood, they are more likely to be trying to track reality. Traders, intelligence analysts, gamblers, and engineers tend to have stronger truth incentives because mistakes cost them.
If someone operates in an environment where errors carry no penalty, the BS risk rises. Think tank fellows, pundits, journalists, and academics can often make confident predictions with no consequences if they are wrong.
Look at willingness to make risky predictions.
Truth optimizers eventually stick their neck out. They make specific claims about what will happen or what mechanisms are operating.
BS artists prefer safe ambiguity. They talk in abstractions and caveats. They avoid statements that could later be clearly judged wrong.
Look at whether they update.
Someone trying to track truth will occasionally say something like: I thought X but the evidence now points to Y.
Someone doing alliance signaling almost never updates publicly. If the coalition view changes they quietly shift language without acknowledging the earlier position.
Look at how they treat opposing evidence.
Truth-seeking analysts engage with inconvenient facts. They try to explain them even when it weakens their case.
BS usually involves ignoring disconfirming information or reframing it as irrelevant.
Look at who praises them.
If praise comes mainly from a single ideological or institutional tribe, that is often a sign the person is serving that tribe’s narrative.
People who are genuinely tracking reality often irritate their own side because reality does not always cooperate with group loyalty.
Look at the level of mechanism.
Truth-oriented explanations focus on mechanisms. Incentives, resources, constraints, tradeoffs.
BS explanations focus on narratives. Intentions, virtue, villainy, moral drama.
Mechanisms are testable. Narratives are flexible.
Look at rhetorical tone.
Heavy moral language often signals coalition signaling. Words like responsible, reckless, historic, dangerous, offensive, brave.
Truth optimization tends to sound more boring. It talks about probabilities, constraints, and tradeoffs rather than moral judgment.
Look at whether they talk about fuel.
Events that actually change the world require fuel. Power, money, manpower, institutions, geography.
Experts who focus on speeches, norms, and intentions without discussing the underlying fuel are often doing narrative management rather than analysis.
Finally, watch what they avoid.
Sometimes the clearest sign of BS is silence about the obvious. If a speaker carefully avoids mentioning the incentive structure that explains the situation, it usually means acknowledging it would threaten their coalition.
A rough rule helps.
Truth optimization tries to explain how the world works even when the explanation is uncomfortable.
BS tries to produce statements that keep allies happy and reputations intact.
In the framework of David Pinsof, an expert is usually a status-seeking primate. The distinction between truth optimization and bullshit does not rely on whether the expert lies, but on whether they care about the truth at all. A bullshitter says whatever achieves a social goal, such as enhancing prestige or signaling loyalty to a tribe. Truth optimization might occur by accident, but it is rarely the primary objective.
To distinguish between the two, you look for the presence of social signaling. If an expert uses vague or deep-sounding language that lacks clear, falsifiable claims, they might be bullshitting. This “vague bullshit” allows them to appear profound while avoiding the risk of being wrong. You should check if their claims are designed to “dunk on” rivals or flatter a specific audience. When an expert identifies an outgroup as “inferior” or “biased” while exempting their own circle from those same human flaws, they are likely signaling status rather than seeking truth.
Another sign is the “pseudo-argument.” These are arguments that sound logical but are actually glib rationalizations for an underlying social preference. If the expert becomes defensive or shifts the goalposts when challenged, they might be protecting their status rather than refining their understanding. Truth optimizers tend to be more attentive to incentives and their own spectacular mind-reading powers that might bias their views.
Finally, consider the incentives. Pinsof argues that humans have a powerful motive to signal because they are judged by hyper-judgy peers. If the expert’s conclusion perfectly aligns with what their peers want to hear, the logic of status signaling is likely at play. An expert who is actually optimizing for truth might occasionally say something that loses them status or makes them look “cringe” to their own group.
