This Explains So Much

My speech therapist mentioned this.  6/13/18 Science Alert:

"A defining trend in human intelligence tests that saw people steadily obtaining higher IQ scores through the 20th century has abruptly ended, a new study shows.

The Flynn effect – named after the work of Kiwi intelligence researcher James Flynn – observed rapid rises in intelligence quotient at a rate of about 3 IQ points per decade in the 20th century, but new research suggests these heady boom days are long gone."

IQs are dropping 7 points per generation both in Norway and Britain since the 1970s.

This is even happening within families so it is not the Idiocracy syndrome.
