Up ’til now, I’ve more or less considered being methodical and being logical as being pretty much the same kind of thing. However, there seems some relevant distinction:
Logical: an ability of mind to understand coherent structure
Methodical: a pratical ability to apply a structure consistently
I remember at uni it often used to frustrate me that amazingly logically intelligent people could be so haphazard in their approach to work. (I suppose when I was feeling harsh, I’d blame them for laziness, as I couldn’t rationalise how it could be a lack of ability.)
Yet, it seems this distinction is at the heart of it – perhaps they were logical, but not methodical. So although they could understand and agree with a coherent structure of work (i.e. the plan) they didn’t have the relevant skills to actively carry out that structure.
