There's tons science courses, maths courses and stats courses on the internet where you learn these things in depth. Most documentaries are often 'pop' takes at things.
I think the BBC are actually really great at avoiding the pop trap. They either do it very well or they just don't do it. I'd point to a lot of popular podcasts as "pop" rip offs of BBC pieces.
"Stuff you should know" is really just "In Our Time" with easier topics and no experts for instance. Plus no 500 episode backlog over several decades.
