Biographical information is not expected to predict all future behaviours but it is useful in personal selection in that it can give an indication of probable future behaviours based on an individual's prior learning history. Biodata instruments (also called Biographical Information Blanks) have an advantage over personality and interest inventories in that they can capture directly the past behaviour of a person, probably the best predictor of his or her future actions.
While biographical information is not a perfect predictor of future behavior, it can provide valuable insights into potential future actions based on an individual's past experiences and learning history. Biodata instruments (also known as Biographical Information Blanks) are more effective than personality or interest inventories in capturing the past behaviors of individuals, which may be the most accurate predictor of their future actions.
