Sowell bump
Of course we are all bribed in a way - do you think that I or most other people would get up early, drive an hour to work and sit in a cubicle all day if we were not getting paid - of course not.
However, Sowell's argument breaks down here and it shows that he is being intellectually dishonest to not continue his thoughts a little further - so I will.
When I get paid\bribed by my employer I have to speak the corporate line when I talk with customers. It does not matter what I think, or even in some cases what the truth is - I need to speak on behalf of my company and if the company says "x" (as long as "x" is not illegal) - then it is my job to speak to that position.
Very few people can publicaly disagree to customers with their corporate positions and continue to be paid\bribed by the company.
Henceforth, we can clearly see that these scientists would not be paid for a position paper that supported global warming - therefore they have a vested interest in producing papers that match the criteria their payer\bribers expect.
While I am not saying that every scientist who writes a paper against the theory of global warming does not believe it - however, like speaking with a company's representative - you cannot really be sure of they really believe vs. what the company line is.
Therefore, yes, we need to be very skeptical of papers written by either side when there is cash on the line to match the check writers position.
