The researchers attempted to clarify how twin experiments are used to investigate the effect of genetics on human behaviour in this article. The question they were attempting to address was how important genes are in deciding individual psychological characteristics. They discovered that the associations for various traits were very close, indicating that genetic influences tend to account for the majority of differences across a wide range of human characteristics. However, there are some flaws in their research. According to certain reports, researchers did not report their data as fully as they should have. They also argue that the researchers did not take into account all environmental variables that were listed in other reports. The findings revealed that identical twins raised in diverse cultures grew up to be very similar adults, not just in appearance but also in psychology and personality. It also shown that, due to the superiority of genes, the environment has no impact on twins raised in the same environment. One important finding from this research is that "not only is the vocation you chose primarily dictated by your genes, but also that about 30% of the difference in your overall career satisfaction and work ethic seems to be attributed to genetic factors," according to a study from the University of Minnesota.
