This whole conversation sounds to me like people arguing whether width or height is a more important factor to the area of a rectangle. Or perhaps what percentage of the total each is responsible for.

It seems we humans are desperate to associate everything with a single cause, or if it has multiple causes, allocate causality to x% of multiple factors. However, success quite often has multiple contributing factors and exhibits "the chain is as strong as its weakest link" type behaviour. When phrased in terms of the contribution width and height make to the area of a rectangle, a lot of the conversation sounds like a category error. A lot of the metaphors we try and apply quite simply do not make sense.
