Hoo boy, it’s a trap. That’s the thing about heretical ideas, I can get downvoted and possibly banned from the site from even gesturing in their general direction.

But okay, here goes. Here are some areas where there’s a very large “dead zone” of ideas which surrounds some bad ideas but which may also encompass some good ones too:

1. Intrinsic statistical racial differences or other ideas labelled as racist

2. Intrinsic statistical sexual differences or other ideas labelled as sexist

3. Maybe some aspects of the Holocaust have been exaggerated?

4. (Increasingly) Climate change skepticism

I wish to stress, once again, that all of these heretical regions certainly contain a bunch of bad ideas at their core; but the size of the fenced-off region in each case is so large that it makes you wonder whether some good ideas have been fenced off too.
