IQ scores dropping around the world

CBS Sacramento - IQ scores have been steadily falling for the past few decades, and environmental factors are to blame, a new study says.

Norwegian researchers analyzed the IQ scores of Norwegian men born between 1962 and 1991 and found that scores increased by almost 3 percentage points each decade for those born between 1962 to 1975 — but then saw a steady decline among those born after 1975.

Similar studies in Denmark, Britain, France, the Netherlands, Finland and Estonia have demonstrated a similar downward trend in IQ scores, said Ole Rogeberg, a senior research fellow at the Ragnar Frisch Center for Economic Research in Norway and co-author of the new study.

....These environmental factors could include changes in the education system and media environment, nutrition, reading less and being online more, Rogeberg said.

is IQ a valuable metric? Better be careful with that idea. It quickly unravels the progressive tapestry into an incoherent mess. The wrong questions will pop up.

For example: Why are IQ tests taken around the ages of 11-13 used as the standard so often? They do measure IQ outside that range, but the 11-13 bell curves get shown to everyone. Why?
