Absolutely. Different studies have found somewhat different lists of top LSAT scores by major, but Philosophy and Math are pretty much always among the top group. Physics (obviously close to math), and Religion and Classics (close to Philosophy) also tend to do well.
As usual, though, there is a bit of a chicken and egg problem here because people who are already better with that sort of reasoning may be more likely to be drawn to such majors. But it likely isn’t bad to reinforce it anyway.
