Our findings may have important implications for other behavioral researchers by providing a new perspective on the online user voting behavior. In addition to confirm the widely known “negative bias” effect [24], our results show that the reviews with the most extreme opinions have a higher probability of getting more votes, suggesting that people tend to pay more attention to those extreme opinions. The effect of “extreme opinions” on other's attention has not been much discussed in previous information systems research and might be an interesting area for future research.
