&gt;  There are systematic biases in the social sciences, and there are systematic biases in physics. Read Lee Smolin&#x27;s The Trouble with Physics. As they are social systems, they will always be biased. And the most dangerous bias is the one that claims itself unbiased, fully objective.<p>I never claimed physics was bias-free. I just said that political affiliation likely imparts less bias on physics than it does on sociology. And that was just one example of a possible source of bias.
