When brilliance in one area doesn't translate to another.

This happens in lots of different fields. I feel like people need to start developing pseudonyms when they achieve success, so that they still get feedback. Either that, or they have to carefully cultivate a group of no people to hang around and tell them which ideas are stupid.

Radical in their area of expertise. If you have spend decades building certain mental models and then theoretical models that most likely work well(as you were rewarded for them) you are likely get stuck in following those.

Does not mean you have well working models outside these. Or that those same models will work well in entirely distinct contexes.
