title: The moderating role of need for cognition on excessive searching bias: a case of finding romantic partners online.
abstract: Using online-dating websites to expand social networks and form close relationships is popular for people in information technology era. Wu and Chiou (2009) demonstrated that more options triggered excessive searching, leading to poorer decision-making and reduced selectivity. They proposed that the more-means-worse effect refers to more searching leads to worse choices by reducing users' cognitive resources, distracting them with irrelevant information and reducing their ability to screen out inferior options. A 2 by 2 experimental study was conducted to investigate the moderating effect of individual differences in need for cognition (NFC) and number of available options on excessive searching and decision quality. A total of 120 undergraduates with experiences of online romantic relationships participated in the experiment. After participants were administrated their need for cognition, they were assigned to review either a small or a large number of options to search for their most desirable romantic partners via a popular online-dating website in Taiwan. Results indicated that high-NFC participants showed more excessive searching than did low-NFC participants. Moreover, the more-means-worse effect was more salient for high-NFC participants than high-NFC participants. The findings suggest that users with high NFC may be more vulnerable to the negative effect of excessive searching.
