Wow, thanks for the high praise Derb. Another point on conservative science from Nisbet. He argues that for all of the ethics and rules of the scientific establishment, the most effective insurance against group-think is competition between scientists and scientific institutions. Arranging self-interest against self-interest is the most sure-fired way to keep scientists motivated to debunk the work of other scientists. I think this highlights what is so dangerous about the current global warming debate; the “mainstream” scientific community is so overwhelmingly encouraged to compete only in one direction. Scientists who question the assumptions of the whole endeavor are locked out of the process, ridiculed or censored through impoverishment.
