I remember recently reading a study that looked at possible correlations between political beliefs and squeamishness. They asked about 20 questions in each area, and found that 3 of the political questions correlated to 8 of the squeamishness questions at the 95% significance level. Recall that 95% significance means "5% chance this correlation is a fluke". Correlating 20 questions with 20 others gives you 400 possibilities; they found 24 correlations. Given 400 trials, if there was no real correlation, they should've found about 20 flukes. Needless to say, I was overall unimpressed by their results.
