I thought quite a bit before putting this up. While I support Simon Singh, I have doubts about Sense About Science. Sense About Science is loosely connected with Spiked Online through Living Marxism, which seems to think Christopher Monckton is a credible speaker on climate change. The climate change debate is one of the major sources of pseudoscientific nonsense on the web, so it’s disappointing that Sense About Science has so little on the topic. In the end I signed because Jack of Kent is asking for signatures. It was a big help that George Monbiot and Nick Cohen, who are aware of the history of the group, signed. Even now I’m not comfortable with the title of the letter, which implies scientists might somehow be exempt from laws that apply to everyone else.
This is another reason why I’m wary of signing anything that gets passed along by a group. If you want to sign with honesty you need to look into exactly what you’re signing. Often there simply isn’t time to do that.
