Teens’ Intellects Can Gain or Lose Twenty IQ Points Over a Few Years
This is the age old question between nature versus nurture that determines intelligence.
Nature Within a range of development, you are born with the best you can do.
Nurture The activities, environment, and coaching shapes intellectual ability.
Researchers at the University College London reported in an article in the Wall Street Journal that IQ may be more malleable up and down than previously thought. According to the Scientist, experience can readily alter the brain, as neural synapses bloom in response to activity or deteriorate due to inactivity.
The study shows that challenge and favorable external factors actually improve intelligence up to 20 IQ points. It even names tutoring as a resource to improve intelligence that contributes to school performance and job prospects.
