A novel look into ownership phenomena. People’s tendency to overvalue owned objects has been often explained through self-enhancement – viewing owned things in a more positive light. However, recent research by Yunhui Huang (Nanjing University, China) and Yin Wu (Shenzhen University and Peking University, China) proposes other-derogation as another potential explanation. According to this research, the higher value people place on self-possessions can also be explained by their tendency to view other-possessions less favorably. Other-derogation can be another underlying mechanism that explains the ownership effect besides self-enhancement.
