Ah I missed “socioeconomic” quintiles, thanks for politely clarifying. The way I see this is - intelligence is genetically determined, but success is determined by behavior, not intelligence. Intelligence just enables more adaptive behavior selection, all else being equal. Environmental factors can inject behavior patterns that override whatever analytic potential a person has. Which I think basically lines up with what you are saying.
