What if new-born babies were given a DNA report card that predicted their intelligence, their odds of getting a PhD, their chances of becoming a chain smoker or suffering depression, a heart attack or cancer? Today, a large amount of genetic data are available, involving millions of people. This wealth of information available to researchers is allowing them to create a polygenic risk score based on the DNA test of an individual. This predicts a person's chance of getting a disease, his or her traits and behaviour. Are these predictions perfect? What if you do not want to know what could happen to you? What if these data were used or abused by others?
