As for your generalized statement asking about less intelligent people having a lesser degree of self control? Maybe persons without a formal education might be disadvantaged in terms of missing out on the different ways of self manipulating and/or understanding ones own emotional state and motivations. That's not saying they're not capable of self analysis or correction but that they aren't aware of the possibilities as someone who had a chance to study sociology, psychology, structured spiritual disciplines, etc....
Has it not struck you as odd, that the argument for the boy who was emotionally adept at comprehending flow of general calm, who later.. For example goes to war or suffers some other life changing experience, might not wish to use your theories on what constitutes intelligence, in order to manipulate himself and others?.
What strikes me drastically about this world is that plain truth and no attempt to emotionally coerce people is met with negativity, you may have won between you, with your gentle lies of killing truth softly, but I assure you that does not make you smarter, or right.
They use that soldier to carve up the world into chunks, what you will ignore and spite, results in where to push the envelope of your own ignorance's, placing a box of your request around you, sure you asked for calm.. You even asked for diversity midst explanations.. But did you really ask for a blinker?.
Emotion is clearly a lockout of all else, even in it's control, across the variances of billions, intellectually.
To lockout and ignore one attitude calmly, still leaves the energy state you are in with a different view to the onus. However you might hide it.
Millions of the billions, if not billions, are ready to smite when given the 'immunity' to do so in scientific tests, in closed situations, the species is so flawed, they have proven it.
All that changes in the view upon such an aforementioned onus, is diverse tactic.
More malleable, do you mean?
Or more diverse?
Or more focused to purity in selected developed sections, less diverse than possible by letting emotion run free across the entire range of energy alterations, RE: accepting avenues of least resistance which make for complex and confusing days, if not halted in numerically lesser quantities of range in spectrum slices?
