Gurwinder explains why people well above average intelligence are actually more likely to adopt irrational ideas:
What causes delusion?
The prevailing view is that people adopt false beliefs because they’re too stupid or ignorant to grasp the truth. This may be true in some cases, but just as often the opposite is true: many delusions prey not on dim minds but on bright ones. And this has serious implications for education, society, and you personally.
In 2013 the Yale law professor Dan Kahan conducted experiments testing the effect of intelligence on ideological bias. In one study he scored people on intelligence using the “cognitive reflection test”, a task to measure a person’s reasoning ability. He found that liberals and conservatives scored roughly equally on average, but the highest scoring individuals in both groups were the most likely to display political bias when assessing the truth of various political statements.
In a further study (replicated here), Kahan and a team of researchers found that test subjects who scored highest in numeracy were better able to objectively evaluate statistical data when told it related to a skin rash treatment, but when the same data was presented as data regarding a polarizing subject — gun control — those who scored highest on numeracy actually exhibited the greatest bias.

Since we’re a social species, it is intelligent for us to convince ourselves of irrational beliefs if holding those beliefs increases our status and well-being. Dan Kahan calls this behavior “identity-protective cognition” (IPC).
By engaging in IPC, people bind their intelligence to the service of evolutionary impulses, leveraging their logic and learning not to correct delusions but to justify them. Or as the novelist Saul Bellow put it, “a great deal of intelligence can be invested in ignorance when the need for illusion is deep”.
What this means is that, while unintelligent people are more easily misled by other people, intelligent people are more easily misled by themselves. They’re better at convincing themselves of things they want to believe rather than things that are actually true. This is why intelligent people tend to have stronger ideological biases; being better at reasoning makes them better at rationalizing.
This tendency is troublesome in individuals, but in groups it can prove disastrous, affecting the very structure and trajectory of society.
For centuries, elite academic institutions like Oxford and Harvard have been training their students to win arguments but not to discern truth, and in so doing, they’ve created a class of people highly skilled at motivated reasoning. The master-debaters that emerge from these institutions go on to become tomorrow’s elites — politicians, entertainers, and intellectuals.
Master-debaters are naturally drawn to areas where arguing well is more important than being correct — law, politics, media, and academia — and in these industries of pure theory, secluded from the real world, they use their powerful rhetorical skills to convince each other of FIBs. During their master-debatery circlejerks, the most fashionable delusions gradually spread from individuals to departments to institutions to societies.
Some of these FIBs can now be found everywhere. A particularly prominent example is wokeism, a popularized academic worldview that combines elements of conspiracy theory and moral panic. Wokeism seeks to portray racism, sexism, and transphobia as endemic to Western society, and to scapegoat these forms of discrimination on white people generally and straight white men specifically, who are believed to be secretly trying to enforce such bigotries to maintain their place at the top of a social hierarchy.
