"Science" (scientists) studies the physical realm almost exclusively, and where it does venture somewhat into the metaphysical, it brings a lot of baggage that works excellently in the physical realm, but is often detrimental in the metaphysical. Plenty of scientists, I'd bet money even most, find[1] metaphysics to be ~silly...except of course when they are whining about it (politics, economics, society, etc..."the real world").

[1] The context, or set and setting, makes a big difference in how they will behave. But the range of behavior is actually pretty simple, far simpler than much of the programming problems we breeze through on a daily basis, without even thinking twice about it. I'd say the problem isn't so much that it's hard, it's more so that it is highly counterintuitive, a lot like Einstein's relativity when first encountered (or even after understood).
