Depends on how the group is defined. I've found myself in the group of people defined as "with IQ score below 140" and you can say, with high degree of certainty, that I'm less intelligent than group of people "with IQ score at or above 140", but I don't lose much sleep about it. Also, what exactly "intrinsically less intelligent" means? For example, I'm statistically more likely to be less intelligent than people of some ethnic background, but this effect is slight enough so that every time I'm compared to a person from this group (and he has to be randomly chosen, and I have to have no other information about him/her other than his ethnicity for this whole premise to work, btw), it's like 55%/45% in his favour, not 100%/0% - not a reason to drop out either.
