Many people think of IQ as a genetic trait like eye color, something you’re born with and stuck with for life…..? But mounting evidence is shedding a different light.
A growing body of research is showing that a person’s IQ can rise—and even fall—over the years and through an individual’s lifetime.
– Alfred Binet, inventor of the original IQ test, 1909
One study shows changes in IQ after just a few weeks of effort. 33 British students were given IQ tests and brain scans at ages 12 – 16 and again about 4 years later, 9% of the students showed a significant change of 15 points or more in IQ scores. These changes were not due to measuring errors because the MRI’s showed changes in gray matter which is linked to IQ. Am I surprised? No! We, the teachers see improvements daily especially when extra efforts are put in.
- measure developed skills, not native intelligence.
- can change dramatically.
- say nothing about a person’s intellectual limits.
