And lab mice aren’t elementary particles, even though inbreeding can make them extremely similar, DNA-wise. Even if they were, they aren’t humans, so extrapolating to them is an art in itself (physicists rarely do experiments with electrons and draw conclusions about neutrons from them)

That it is harder to draw conclusions from experiments in biology than in physics doesn’t imply biology isn’t a science. Economics adds the problem that we (rightfully) don’t want to do realistic controlled experiments (would at times be hard, too. Put a few million people in a country with a given law regime, watch for a couple of decades, draw conclusions. Repeat) but again, to me, that doesn’t imply it isn’t a science.

I think it’s more part of the humanities than a science, though.
