not everyone is aware of the "methodology", they just think it through, some however have an executive layer to cognition vs reflex.
imnot sure enough to form an opinion quite yet but thinking about thinking, modifying the methods of cognition, may be a learned skill, perhaps with a developmental window.
a comparison between extroverts and introverts [1] for perceived modality of cognition might be interesting.
it may very well be that a difference in neural development is the cause of this disparity.
1] this is about focus on internal conceptualization vs external perceptualization.
myself, i think in terms of a mono/dialogue if i am preparing to disseminate.
if i am thinking for my own benefit i percieve it as idetic imagery and run thought experiments to qualify for IRL candidacy.
