According to Starch Research Professor of Psychology, Jerome Kagan, shyness has been found to be an inherited biological trait that can be detected in infants as early as four months. There are a number of factors that can help individuals overcome their shyness, so it isn’t necessarily a life sentence. Kagan’s research found that only 25% of children that exhibited extreme shyness as children will be extremely inhibited as adults. This should be good news for the shy introverts that believe they always will be.
