I enjoyed this talk by Ben Goldacre about his work on exposing bad conduct by big pharma scientists.
I was particularly taken by his opening gambit, namely that science rejects argument from authority. Too right. However, I couldn't help but be reminded of Simon Singh's contribution to the Spectator debate, which was essentially argument from authority from beginning to end. Perhaps Dr Goldacre should give his friend Dr Singh a lesson in basic scientific philosophy.
There is also a good section on data availability, another area on which the official sceptics might like to spread their criticisms around a little bit more widely.
