Adventures in selection bias
I always love a naughty research study, and this one sounded like fun: Spanking 'brings couples together'...
Researchers at Northern Illinois University measured stress hormone levels in couples engaging in S&M activities, and found evidence that these activities, while causing some anxiety at first (which, I suppose is the point, right?) ultimately left the couples feeling closer.
And what was their research sample? People attending an S&M party.
Yes. Really.
So... S&M brings couples who are into S&M closer? You don't say!
