According to an article I found on BBC.com, it looks like our IQs are starting to recede, or at least not continue upwards as they have been doing.
Intelligence tests (IQ tests) were invented a little more than a century ago and since that time, our scores have been increasing at a steady rate. According to studies “even the average person today would have been considered a genius compared to someone born in 1919”. (Unless you’re comparing yourself to Albert Einstein (born 1879), then all bets are off.) This steady increase in IQ is known as the Flynn Effect.
But now scientists have uncovered evidence that this trend may be slowing down and perhaps even reversing. Does this mean we’ve peaked as a species?
Of course the cause of the Flynn Effect has never been agreed upon by the scientific community; most seem to think that multiple environmental factors are involved (increased health, increased food availability, increased access to education, removing lead from gasoline), but nobody really knows for sure. It’s my guess that if there is a decline of our collective IQ on the horizon, no one will understand that either.
Who is the smartest person you know? Or what smart person would you LIKE to know?
