On the malleability of confidence in preferences

People acquire preferences for products such as candy or apples through experiences. When these experiences are more similar (candy is almost always tasty) we gain more confidence in our preferences than when the experiences are more dissimilar (apples can be tasty or bland). Confidence in preferences is useful as it summarizes previous experiences, but it may cause difficulties with resisting temptations. This project examines the changeability and malleability of confidence in preferences, and how this confidence can hamper and stimulate resisting temptations.
