The IKEA Effect

Building something oneself enhances feelings of competence, leading individuals to value their creations more highly than identical pre-assembled products. This phenomenon, known as the IKEA effect, suggests that self-made items serve as badges of personal competence, signaling identity to both oneself and others. When the importance of competence is diminished, the overvaluation of self-created products decreases, reinforcing the connection between personal achievement and perceived worth.
