I think social dynamics are real and must be answered for but I don't think any self-correction or lacktherof has anything to do with subject matter which can be understood independently.

I will never take a proponent of The Bell Curve seriously who tries to say they're "just following the data", because I do hold them and the book responsible for their social and cultural entanglements and they would have to be blind to ignore it. But the book is wrong for reasons intrinsic to its analysis and it would be catastrophic to treat that point as moot.

I am saying that those who actually believe something won't stick around and associate themselves with the original movement if that movement has taken on traits that they don't agree with.
