Although it mentions the global warming debate, it’s really more about being skeptical in general:
A number of political commenters have compared the current Republican contestants unfavorably with Barry Goldwater. The current crop, we are told, are religious nutcases, or possibly pretending to be. Goldwater, on the other hand, was an intelligent and reasonable man, even if not on the right side of every issue.
I have been reading my parents’ autobiography, and recently got to the Goldwater campaign. Their description fits my memory. What we were being told then — by people almost none of whom could have done a competent job of explaining Goldwater’s positions or the arguments for them — was that he was a dangerous madman. There was even a piece by some large number of psychiatrists, none of whom had ever examined the candidate, explaining how crazy he was. And the TV ad with the little girl, the countdown, and the mushroom cloud.

I am not competent to judge the climate science behind global warming, but I am suspicious of orthodoxies pushed relentlessly in the popular media, orthodoxies that claim that everyone competent agrees on an urgent problem which requires drastic action immediately if not sooner. I remember when we were being assured that it was simply a scientific fact that overpopulation was the cause of poverty and a near term threat to our own well being, if not survival. Also when we were assured that the only way to get the poor countries of the world up to our level was central planning, if possible supported by generous foreign aid.
When I see news headlines about global warming having shrunk horses to the size of cats, along with a picture comparing a cat sized dog to a modern Morgan — you have to read down a bit to discover that the ancestral horses shrank to the size of cats from the size of dogs, from 12 pounds to 8 1/2 pounds, and spent tens of thousands of years doing it — I suspect that what I am seeing is driven at least as much by what people want other people to believe as by the evidence for believing it.
