The effect of social crowding on individual preference for self-improvement products

Perceived social equity was measured by answering “To what extent do you think society is fair?” We then calculated provincial population density and employment rate. Experiment 1 documented the effect of social crowding on self-improvement products in a laboratory setting. We found that social crowding strengthened participants’ preference for self-improvement products, but it did not significantly change their liking toward general products. The results of Experiment 2 replicated the effect, that is, participants mainly preferred self-improvement products when feeling crowded ( M crowded = 3.77, SD = 1.65 vs. M uncrowded = 5.07, SD = 1.48), F (1, 58) = 10.27, p = 0.002, Cohen’s d = –4.53. This effect was mediated by the need for self-improvement (95% CI = 0.0108 to 0.6388). Experiment 3 ruled out the mediating role of perceived busyness (95% CI = –1.2613 to 0.4922). In Study 4, linear least squares (OLS) confirmed the effect of population density on the frequency of residents’ learning to improve themselves. We further examined the moderating role of perceived social equity and employment rate. Perceived social equity moderated this effect, that is, when people perceived social equity as high, the influence of crowdedness on self-improvement behavior was intensified. However, this effect was attenuated when social equity was deemed low. In addition, high density strengthened the self-improvement behavior of participants from regions with low employment rates. However, this effect was attenuated for those from regions with high employment rates. In summary, this research provides an initial investigation into the influence of social crowding on the preference for self-improvement products and its underlying process. This research contributes to the existing literature by identifying the positive behavioral consequence of social crowding.
