Oh well many said it was a stupid theory.....
here we go again
Reaction times – a reliable marker of general intelligence – have declined steadily since the Victorian era from about 183 milliseconds to 250ms in men, and from 187ms to 277ms in women.
The 1916 Heuer Mikrograph made history by being the first stopwatch capable of timing to 1/100th of a second. Previously timing was only precise to 1/5th second.
People losing their intelligence has nothing to do with evolution. It's a completely artificial man made cultural, and social disorder.
Reaction time doesn't have to have anything to do with intelligence, actually it can have an opposite effect.
Researchers have reported medium-sized correlations between reaction time and measures of intelligence: There is thus a tendency for individuals with higher IQ to be faster on reaction time tests... Several studies have reported association between simple reaction time and intelligence of around (r=−.31), with a tendency for larger associations between choice reaction time and intelligence (r=−.49)
