I strongly agree with your high regard for Physics and for the ethics that dominates the work of physicists and mathematicians.
And I do see an "end justifies the means" tenet among all the historical sciences - obviously evolution, but also archeology, anthropology, Egyptology, etc. The absence of evidence in the historical record leads to speculation, "just so" stories to fill the gaps. This would not be so troubling were it not for the peer review process and the politics of the academia.
In the end, the layperson such as I am, must remember that all of these theories emanating from the historical sciences may be the result of a committee, a group-think.
And of course, any democracy of this sort would be influenced by the very things Popper mentioned in his essay excerpted at post 47.
Well said, A-G.
Obviously, you've never been to a scientific conference. It's no different in the "historical" sciences than in any other field. There are always plenty of colleagues ready and eager to ripe your theory to shreds.
