I agree that that sentence could give that impression but I think it's a little out of context. If you read Simon Singh's stuff (particularly Trick or Treatment, the book which lead to the article which lead to the libel case) it's really not what he advocates - he advocates having a robust evidence base for what you're saying. I think what he was trying to say in the sentence you quote is "I believe the overwhelming majority of the people who have looked at this subject, have a history of backing up their claims with robust, tested, reviewed evidence and are doing so in this instance".
