Researchers studied DNA from 1 1 million people and came up with a scoring system  The system can be used to detect someone's DNA to roughly predict someone's education level  It turns out that only 10% of those with the lowest genetic scores  In contrast, those with a genetic score in the top five have a 50% chance of graduating from college  This is the largest study of human cognitive genetics in history
Based on this, some people believe that there is a great connection between human genes and academic qualifications
Among the 1.1 million people who are studied, sampling shows that less than 30% are college graduates.
