I’ve said it before but it is worth repeating: Science and job don’t mix very well. Career demands can make it hard to tell the truth as you see it. A scientist named Norman Rogers put it like this in relation to global warming:
Mainstream climate scientists are asking for trouble if they become skeptics [about man-made global warming]. They may lose their jobs, their papers may not be published and they may lose their grants. ThatÊ¼s why most skeptics are older or retired or from outside of the mainstream – they are less vulnerable to retaliation.
He could have added that global-warming skeptics will have difficulty recruiting others, such as graduate students, to work with them and will face disdain from their colleagues.
I saw this in relation to the work of Ranjit Chandra. At Berkeley, when I told other professors about my doubts, one of them replied: Talk to X. He’s had doubts about Chandra for 30 years. I spoke to X. This was correct. I didn’t ask X why he’d never said anything publicly about it because the reason was obvious: He feared retaliation.
