It may be that certain theorems, if they prove true, are intuitively delayed
Progress in specific areas. Lloyd Trefethen provides two examples:
- Faber's theorem on polynomial interpolation
- Squire's theorem on hydrodynamic instability

In my own experience, I have seen the various negative results sets

hamper progress in neural network research for more than a decade.1
Q, What are other examples of theorems, their (correct) evidence (possibly temporary)
Suppression of research in mathematical subfields?

Abstract: "[…]I particularly focus on the evidence and arguments of Minsky and Papert, interpreted as meaning that further advances in neural networks are not possible and that this approach to AI has had to be abandoned.[…]"
