Thanks for eloquently stating a problem I've noticed for a while. I think there's a fear of not coming off as a hard-nosed, logical thinker, so the constant need for citation is a proxy for "I believed XYZ because some authority said it was true. If I'm wrong, it's not me, it's because I was mislead."

The world is full of single data points. If you see an anecdote, see it as a data point, but more importantly, see it as a metaphor which could apply to your situation.

Sometimes I think some people wouldn't hug their kids until a study said it was ok (hrm, weren't there studies in the 50s saying you should do the opposite?). I'd like to think I'm rational, but sometimes you need to move beyond the cover-your-ass safety net of "the study says" and do what feels right. Citation? Here's a meta-study that most medical research studies are false (http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1182327/).
