Neuroscientist and professor emeritus at the University of California, Irvine,
Robert Haier, stated that for the first time in human history the concept that
intelligence can be increased is reasonable. If the brain mechanisms
that determine intelligence are understood, then the possibilty that those
mechanisms can be improved or tweaked exists. Haier found brains with higher
intelligence are highly integrated with neural paths connecting distant
brain regions. Less intelligent brains were found to have shorter, simpler
neural paths. People would be able to learn faster and remember more
if scientists can develop a way to improve those long range connections.
Average IQ is a score of 100 and the test doesn't really measure up to
200, but the author proposed what would the world be like if the average
score was 200. It is believed Isaac Newton would have had a score of 200
if he took the IQ test. Earl Hunt, professor emeritus of psychology at The
University of Washington and president of the International Society for
Intelligence Research stated approximately one person in 10 billion would
have a score of 200 and no one is on record with that high of a score at
this time. If we were smarter, we would be healthier and live longer and
have careers that were interesting. We would be able to solve difficult things
like learn a new language in weeks, invent better technology, and would less
likely believe in God. Smarter people are rated as better looking according
to a Harvard University study so the population would be considered better
than average looking. Having a smarter and more attractive population,
however, does not mean we would have a better society because people
would still have the same personalities and emotional responses.
