Alternative hypothesis: these people have a better framework to discuss "ethics, reality and the nature of consciousness" than people who do humanities have.
That explains the Hawking example in this thread, too.
Proposed causal explanation from me: STEM interest and education gives you skill and tools for principled, consistent reasoning, expressing nontrivial concepts (that's what mathematics is largely about), as well as appreciation and deeper understanding for how things in our actual, physical universe work, from biology and physics to computation. Conversely, humanist base with no STEM experience collapses to rhetoric, completely detached from actual reality.
