Endowment Effect
People assign higher value to items they own compared to identical items they do not own.
Why it works
Based on Thaler's research (1980), ownership creates psychological attachment that increases perceived value beyond objective worth. Loss aversion combines with ownership to make owned items feel more valuable than identical unowned items. This endowment bias affects willingness to trade and resistance to giving up possessions (Kahneman et al., 1990).
