The Economist recently had an article about how sitting in wobbly furniture makes people crave "emotional stability." They also mention a study finding that people sitting in chairs that lean to the left reported more liberal opinions.

The difference is not huge, but it is statistically significant. Even a small amount of environmental wobbliness seems to promote a desire for an emotional rock to cling to.
As far as I can tell they are completely serious.
