The assertion is not grounded in reality at all. It’s a common myth among people who live in a STEM echo chamber. Personally, I don’t know why people who haven’t even done more than a cursory overview of philosophy feel entitled to make meta philosophical claims. My only explanation is that it’s a way to defend a dogma of naive scientism. Why? I don’t know, probably the same reasons why people cling onto religion.
I brought up Tyson because I watched a video recently where this guy argues that this whole perspective is an especially American phenomenon: https://www.youtube.com/watch?v=aD0S1rH8AiE
I'm sympathetic to this even if this lethargic attitude goes back to the religious period as you say. We can at least find the roots of it in the Enlightenment with Newton's "hypotheses non fingo".
