Why I like Dr. Ben Goldacre

I've been trying to keep my posts to once a week on Wednesdays, but sometimes I simply just want to share something interesting. In a recent Bad Science post, Dr. Ben Goldacre discussed sampling error in relation to unemployment figures in the UK. The article itself is interesting, but I found the description of systematic sampling error especially amusing:
Firstly, you’ll be familiar with the idea that a sample can be systematically unrepresentative: if you want to know about the health of the population as a whole, but you survey people in a GP waiting room, then you’re an idiot.
