Nisbett states in his book Intelligence and How To Get it that IQ is gained by educational interventions and parenting styles; contradicting the hierarchy of IQ. He agrees that IQ tests do actually measure something worth note. However the claim is that 75 to 85% of IQ comes from heritage whereas he believes that it’s less than 50%. He performed tests on identical twins that grew up separately in adoptive families. The fall came as adoptive families are too similar in the sense that both families will cause the child to have the correct mental stimulation. This proves there is no fixed value for heritage of IQ. Even if genes plays some role in IQ, it implies nothing about differences between populations. An example would two identical maize seeds planted in different soil. One plant will grow well whereas the other will not; it all depends on the environment. The gap has been shrinking. The IQ difference between black and white boys has dropped from 15 points to 9.5. As for East Asians having a higher IQ than Americans, it was found out the tests weren’t conducted properly and when done properly the Americans tend to score slightly higher scores.
