Hi Tim,

I feel that there are some really powerful messages in your post and the research cited. I am still grappling with it, but one comment for now – you say the “fine grained specificity of exercise may miss the mark” which I read as a roll around on the floor playing a game could be better in some situations than a specific muscle exercise.

Along the same lines and you allude to it in your post – it make me realise that the “fine grained specificity” of education can also miss the mark and that we should be considering the category of misconceptions ( flawed mental models rather than specific misconceptions) and also categories of need (when and how do I get on with life rather than the fine descriptions of a technique that a health professional may have performed).

I would love some more thoughts on this topic

David
