Quite naturally I thought higher IQ scores would favor the young whose mind is more fertile and operating less encumbered by ingrained thought processing patterns.
I think the dip in my estimation is perhaps due to many youths experience with growing technology and lazy brain patterns that develop from technology doing a task that used to require a lot thinking.
Interesting to see what finally develops in this evolutionary cross roads of sorts. Also I think it is a challenge to make a good IQ test that keeps up with the momentous times of change we are living in.
