This honestly makes sense to me. Philosophy basically teaches you how to think about things really well. When talking about STEM folks, however, you're already dealing with extremely analytical people, but to them, analytical thinking is just intuitive.

Spending a bunch of time figuring out why something that seems obvious is obvious probably seems like a waste of time to a lot of people, but it can certainly help in the long run. We can't see our own blindspots, so even if something seems obvious, I think it's useful to understand it.
