Scientists constantly circle each other like sharks, waiting for a sign of weakness. A piece of bad logic would bring them all in for the kill. A piece of bad math would bring in mathematicians as well, and they are even more predatory. They are not working together even if they appear to be working in the same direction.
Your post would make sense if an earnest devotion to truth and honesty were the only thing that drives scientists. It's not.
There's also something called "funding," which Must Be Assured Above All Else. To go for the kill on, say, Global Warming, would risk the funding of everybody else. Best to be quiet, when one's own livelihood is at stake.
There's also that other little item, called "politics," which we saw most clearly during the "Star Wars can't possibly work, and it will cost trillions" festival of the mid-80s.
We cannot pretend that scientists are not also driven by those sorts of things.
You're ignoring that sociologists, anthropologists, and psychologists call themselves scientists.
That's too bad because while I have problems with evolution per se...I am not generally anti-science. The scientific method when applied to the personal self can be breath taking efficient in helping one cut thru ones own personal garbage...though I think of the scientific method applied in this regard as more like the socratic method of self inquiry. Logic and experience made lead one to a climactic personal decision...but they still only go so far...a mature personal morality is one that finds its clarity in the truth and its humility in the wisdom of finally understanding that one knows that one knows nothing of what he really ought! There is still that leap to be made!
You follow the caterpillar and you always come to the crysalis!
