Well, they will or they will die trying.
All babies will turn into all 22 year olds. Only some babies will turn into college graduates.
Therefore some of a population, if selected artificially (i.e. college graduates) will always be better than the whole population (i.e. all babies.)
I completely disagree and as a college graduate I would never say something like that.
A test statement may be: A certain population is at the top of the IQ bell curve therefore they are smarter.
The IQ bell curve being the context.
Most fresh graduates also become retired seniors. All retired seniors eventually become corpses. Can you maybe see potential declining over time now?
A baby could become anyone.
FCG: fresh college grads (natch) LDE: lame-duck elderlies BMPP: babies; max-potential persons
