I wrote a post over at Psychology Today on the psychology behind conspiracy theories about airline disasters like the disappearance of MH370, and more recently, MS804. Part of the appeal, according to a handful of recent studies, may be how conspiracy theories resonate with our brain’s intentionality bias.

When ambiguous events happen, we automatically assume that they were intended, rather than accidental. The bias is easy to spot in kids. When young children see somebody sneeze of fall over, they think that the person must have meant to sneeze or fall over. As we grow older, of course, we realize that people don’t always intend to do everything they do, and we can override our automatic judgment of intent. But the bias stays with us. One study found that having people drink a few shots of alcohol made them more likely to interpret ambiguous events as intentional—which might explain why so many fights start in bars when somebody interprets an innocent comment as an aggressive affront.
