Aeon: Bad thinkers

You realise, of course, that Oliver’s theory about 9/11 has little going for it, and this might make you wonder why he believes it. The question ‘Why does Oliver believe that 9/11 was an inside job?’ is just a version of a more general question posed by the US skeptic Michael Shermer: why do people believe weird things? The weirder the belief, the stranger it seems that someone can have it. Asking why people believe weird things isn’t like asking why they believe it’s raining as they look out of the window and see the rain pouring down. It’s obvious why people believe it’s raining when they have compelling evidence, but it’s far from obvious why Oliver believes that 9/11 was an inside job when he has access to compelling evidence that it wasn’t an inside job. [...]

Now let’s flesh out Oliver’s story a little: suppose it turns out that he believes lots of other conspiracy theories apart from the one about 9/11. He believes the Moon landings were faked, that Diana, Princess of Wales, was murdered by MI6, and that the Ebola virus is an escaped bioweapon. Those who know him well say that he is easily duped, and you have independent evidence that he is careless in his thinking, with little understanding of the difference between genuine evidence and unsubstantiated speculation. Suddenly it all begins to make sense, but only because the focus has shifted from Oliver’s reasons to his character. You can now see his views about 9/11 in the context of his intellectual conduct generally, and this opens up the possibility of a different and deeper explanation of his belief than the one he gives: he thinks that 9/11 was an inside job because he is gullible in a certain way. He has what social psychologists call a ‘conspiracy mentality’.

Notice that the proposed character explanation isn’t a rationalising explanation. After all, being gullible isn’t a reason for believing anything, though it might still be why Oliver believes 9/11 was an inside job. And while Oliver might be expected to know his reasons for believing that 9/11 was an inside job, he is the last person to recognise that he believes what he believes about 9/11 because he is gullible. It is in the nature of many intellectual character traits that you don’t realise you have them, and so aren’t aware of the true extent to which your thinking is influenced by them. The gullible rarely believe they are gullible and the closed-minded don’t believe they are closed-minded. The only hope of overcoming self-ignorance in such cases is to accept that other people – your co-workers, your spouse, your friends – probably know your intellectual character better than you do. But even that won’t necessarily help. After all, it might be that refusing to listen to what other people say about you is one of your intellectual character traits. Some defects are incurable.[...]

Could we explain the dismissiveness of the coach without referring to his personality in general? ‘Situationists’, as they are called, argue that our behaviour is generally better explained by situational factors than by our supposed character traits. Some see this as a good reason to be skeptical about the existence of character. In one experiment, students at a theological seminary were asked to give a talk elsewhere on campus. One group was asked to talk about the parable of the Good Samaritan, while the rest were assigned a different topic. Some were told they had plenty to time to reach the venue for the lecture, while others were told to hurry. On their way to the venue, all the students came across a person (an actor) apparently in need of help. In the event, the only variable that made a difference to whether they stopped to help was how much of a hurry they were in; students who thought they were running late were much less likely to stop and help than those who thought they had time. According to the Princeton philosopher Gilbert Harman, the lesson of such experiments is that ‘we need to convince people to look at situational factors and to stop trying to explain things in terms of character traits’.
