Jason’s post about conspiracies reminded me of several books that support Jason’s argument. 

The first book is How We Know What Isn’t so: the Fallibility of Human Reason in Everyday Life, by Thomas Gilovich (1991). Gilovich points to a number of experiments demonstrating that people strive to find order in the world where there is none.  We don’t find random distributions easy to process.  Rather, we allow our imaginations to run wild on randomness:

With hindsight it is always possible to spot the most anomalous features of the data and build a favorable statistical analysis around them.  However, if properly trained scientist (or simply a wise person) avoids doing so because he or she recognizes that constructing a statistical analysis retrospectively capitalizes too much on chance and renders the analysis meaningless. . . . unfortunately, the intuitive assessments of the average person are not bound by these constraints.

Here’s another good example of people finding order where there isn’t, on Mars.  

People are also “extraordinarily good at ad hoc explanations.” Our motives and fears ignite our imaginations:

Once a person has misidentified a random pattern as a “real” phenomenon, it will not exist as a puzzling, isolated fact about the world.  Rather, it is quickly explained and readily integrated into the person’s pre-existing theories and beliefs.  These theories, furthermore, then serve to bias the person’s evaluation of new information in such a way that the initial belief becomes solidly entrenched. . . . people cling tenaciously to their beliefs in
