بررسی های آنلاین: تاثیر جهان بینی، تشابه اتفاقی و پراکندگی بر نگرش مصرف کنندگان به رستوران های قومی

The current study examines the joint effect of incidental similarity, dispersion, and individuals' cosmopolitanism on customers' attitude and purchase intention in the context of online reviews. A 2 × 2 × 2 experimental design is conducted with incidental similarity and dispersion being manipulated and cosmopolitanism being measured. The results indicate that customers high in cosmopolitanism tend to have a more positive attitude towards a restaurant after reading a set of positive reviews written by reviewers with different ethnic backgrounds (i.e., low similarity condition) compared to the reviews written by people with similar ethnic backgrounds. Customers low in cosmopolitanism show a similar attitude and purchase intention across conditions. Further, this pattern is only significant when dispersion is high (vs. low). The theoretical and managerial implications are discussed.
