Not directly on topic, but too good to pass up.

Several years ago, the American Journal of Political Science published what became an oft-cited study showing a correlation between conservative political ideology and authoritarian/psychotic tendencies.  It now turns out that the authors had their codings for liberals and conservatives "exactly reversed," to quote their language.  In other words, it's the liberals who are (per the study) more likely to be authoritarian nuts.

For those of us accused of being conservative, authoritarian headcases, this was the laugh of the day.
