First off, welcome to Less Wrong! Check out the welcome thread if you haven't already.

You have a good writing style, but I hope you'll pardon me if I make a few suggestions based on the usual audience for Less Wrong posts:

Typically, a post of this length should be broken up into a sequence; you run the risk of "too long; didn't read" reactions after 1000 words, let alone 3000, and the conversation in the comments is usually sharper if the post has a single narrow focus. Usually, the analysis of a situation and the recommendations become separate posts if both are substantial.

Secondly, with the notable exception (sometimes) of P.J. Eby, we're often mistrustful of theories borne of introspection and anecdotes, and especially of recommendations based on such theories. There's therefore a norm of looking for and linking to experimental confirmation where it exists, and being doubly cautious if it doesn't. In this case, for instance, you could find some experimental evidence on choking that supports your thesis. This also forces you to think carefully about what sort of things your model predicts and doesn't predict, since at first glance it seems vague to the point of danger. The more specific you can get about these phenomena, the more useful your post will be.
