See Rational ignorance.

Thinking about this comment reminds me of an important point.

I do have a smartphone in my pocket and I can look up that information in seconds, quicker than I can type this post.

I don't recall exactly when I shifted that belief, but I think it was before I had a smartphone, which means that looking it up would probably take at least minutes, instead of seconds, which may be coloring me thinking now 'I should have just looked up some facts.'

Regardless of the status of beliefs about facts about the U.S. death penalty in particular, I agree there exist certain facts that are worth seconds looking into, that aren't worth minutes looking into (or any other appropriate combination of time increments)

Thanks for bringing this to my attention.
