Asking people how they feel could render so many variances so I'd go with sure, no, and maybe. Ask someone ignorant to any teachings of physics, a high school student who finished highschool physics and an aerospace engineering student how much they know about physics... All of them could say they wish they knew more to fully understand what they wish to understand.

Kind of like that old saying, the more you learn the more you realize you don't know.

Nah, shitty questions as usual. Go around any country and all folks to explain a p value and how is derived.

Unless it's your day job that's just not information the common person retains. A cursory knowledge of what it is and how is used is all that's needed for most.

It says more than half, so it's a sure thing.
