How Movie Maniacs Differ from Real Ones

The difference comes from the demands of the genre. A story needs a worthy opponent, or there will be no tension. Real cases work differently: there is no grand design, only repeated behavior, and solving the case means months of monotonous paperwork.

This creates a distortion in the other direction, too. Movies make it seem as if such crimes are common and hidden geniuses are walking among us. Their share of overall crime is tiny, yet culture gives them a disproportionate amount of attention.

This does not mean psychological analysis is completely useless. It helps narrow the field and set priorities, especially when there are many cases. But it does not point to a specific person, while movies make it do exactly that, often by the final episode.

A genius villain explains something frightening in a comforting way: if the criminal is exceptional, ordinary people must be incapable of such acts. It is much more unsettling to admit that the person behind them is usually unremarkable, with an ordinary background.

This image also causes practical harm. As long as you picture an exceptional person, an ordinary suspect does not fit the image, which gets in the way of both investigators and witnesses. People fail to report a strange neighbor for years precisely because he looks ordinary.
