I'm at the very beginning of Gen X, by the way. Also the very tail end of the baby boomers.
I just want to see OPs sources that show IQs are dropping.
IQ and common sense are different things.
Also, if OP is saying that people born after 1980 are getting dumber - then isn't that on Gen X, who raised them? Maybe toejamty parenting? toejamty schools, toejamty politics - all controlled by Gen X
