Key papers

Schoenmueller, V., Netzer, O., & Stahl, F. (2020). The polarity of online reviews: Prevalence, drivers and implications. Journal of Marketing Research, 57(5), 853-877. What it reports: Over 280 million reviews from 25 platforms; most platforms show high polarity, varying with how selective customers are about reviewing. Secondary data, experiments and a survey show that polarity self-selection, where customers with extreme evaluations are more likely to write, is an important driver and reduces review informativeness.

Key ideas

Polarity Self-Selection: The tendency of customers with extreme evaluations to be more likely to write a review, which makes review sets polarised.
