I think IQ is overrated. Important but used as a single metric of success which I dont think is accurate. Jordan Petersen says the best predictor of success in life is 'conscientiousness' aka the ability to continually show up to something (job for eg) and keep plugging away. Not that IQ isnt important - you still need a decent IQ but its not the be all and end of of potential.

Potential is also subjective. Potential to do harm or good? I suppose that is a moral or perhaps spiritual aspect.
