It's definitely a good idea to be skeptical. There is definitely some badly-designed research out there, and some that shows less than it claims to. The best way to deal with that is to read the original papers and make sure the studies were adequately performed, although this doesn't entirely solve the issue (see: publication bias).
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.
