This is true because those with higher intelligent quotients have higher problem solving abilities that correlate to better life qualities. In an Australian study studied by Gottfredson, motor vehicle fatalities were studied, correlating intelligence quotients with motor vehicle fatalities. In the study, there was a direct correlation discovered between those with lower intelligence quotients, and higher death rates per 10,000 people. Ian Deary of the University of Edinburgh, in the United Kingdom did another study that shows how those individuals with higher intelligence quotients have higher qualities of life than those with lower intelligence quotients. For his study, he looked into the childhood intelligence quotient scores of a group of 80 year olds. In his study, he found that those who scored the highest on their childhood intelligence quotient tests were also the healthiest at age 80. These studies serve as evidence that having a higher intelligence quotient improves the quality of your life. College students who graduate with at least a Bachelor’s degree have on average higher intelligence quotients than those students who didn’t attend college, which means that those students who do graduate college with a degree will have a better quality of life than those who don’t.
