Taking quotes out of context is bogus, lol.
Right, so I do believe that it's impossible to be entirely unbiased. Good scientists know this and try to control for it as best they can. Less good scientists perhaps think that they aren't affected by bias, or can avoid it, or aren't completely aware of the problems it can cause. Dishonest scientists don't really care. In much research, this isn't a huge problem. The research I did was not the least bit political. It was pure basic research, and any eventual profits from it are so far down the line that it wasn't much affected by any political or financial motives (bias is still an issue of course, just not as high stakes). Once politics and money enter, it's a whole different game.
As Kristen said, you just aren't going to get some disinterested party to front the money for a study on a controversial issue. It's not going to happen. It wouldn't make any sense. If a party/organization/funding entity doesn't care about the results, they are not going to pay for the study. That's just common sense. This is how the world works.
I believe that CASAA did everything possible to reduce bias in the study they commissioned. They chose a researcher with nothing to gain from pushing the results in one way versus another. They did not dictate the results. Of course, people are going to use the fact that it was CASAA who funded the study against it, but the alternative is to continue to sit back and just try to defend against the unabashedly biased studies being cranked out by people who truly do have high stakes interests. That, IMO, would be a bad decision.
