"...Dr Nijenhuis studied the results of 14 intelligence studies conducted between 1884 and 2004 to come to his conclusion. Each study measured peoples’ reaction times – how long they took to press a button after being prompted. It is claimed that reaction time mirrors mental processing speed – so it reflects intelligence. They found that visual reaction times averaged 194 milliseconds in the late 19th Century, but in 2004, they had increased to 275 milliseconds. This would suggest that people have become less intelligent, they said."
That's purely metabolic.
