The Times report, based on research, that the younger generations are getting dumber in terms of IQ.
They report that the turning point (somewhere around those born in 1975) marks the end of a well-known but poorly understood trend known as the Flynn effect, in which average IQs have risen by about three points a decade for the past 60 or 70 years.
At the same time, a meta-analysis of 42 datasets from quasi-experimental studies (those using instrumental variables, regression-discontinuity designs, and those controlling for earlier intelligence) involving over 600,000 participants found consistent evidence for beneficial effects of education on cognitive abilities of approximately 1 to 5 IQ points for an additional year of education.
So the current generation seems to have lower IQ regardless of receiving higher education, which has been shown to improve cognitive development. Are there something negatively affecting cognitive development so much as to cancel out the effect of education? or is IQ just not working as a measure of cognitive development??
