>>12329855I'd say what separates smart and dumb boils down to how well a person can abstract out information around them, notice patterns, and successfully execute on plans to achieve goals they set.
Traditionally, this is gauged against logical problems, so some math autist might be described as highly intelligent but socially awkward. For people who can achieve social goals, if you apply this vague definition that, I would describe that 'social intelligence' as charisma, to differentiate the two.
