Following up on my two previous posts, I am posting an excellent TED talk here:

http://www.ted.com/talks/ben_goldacre_battling_bad_science#t-253777

The topic is how trials are distorted by drug companies and others. Ben Goldacre is a very good (and fast) speaker and will give you some ideas of how to look at the evidence.

I thank my friend Julie for sending this to me.
