Choking, perhaps.
Looking at the snippets of Lynds's writing in this article, and the anecdote of his "hurry up and get it" interaction with Grigson, I'd guess one problem he's going to have is a tendency to not explain himself very well.
I think there's always been a camp that believes we think in verbal constructs and if it can't be clearly stated, it isn't cleary thought, and a camp that believes we think in imagery and if the imagery is complex it is difficult to translate into verbal constructs. I suspect the math is be more explanatory.
