Agreed.

Everything in a model is a correlation of behavior with context and context with behavior.

"Mind set" is a factor across the continuum of scales.

Are we solving a math problem or deciding on entertainment? We become entirely "different brains" in those different contexts, as we configure our behavior and reasoning patterns accordingly.

The study is still interesting. The representation, clustering, and bifurcations of roles may simply be one end of a continuum, but they are still meaningful things to specifically investigate.
