The Robo Bias in Conversational Reviews: How the Solicitation Medium Anthropomorphism affects Product Rating Valence and Review Quality

Speaker: Irina Heimbach

Abstract: Companies are increasingly introducing “conversational reviews”—reviews solicited via chatbots—to gain user feedback. However, little is known about how chatbot-mediated solicitation influences rating valence and review quality compared to conventional online forms. Therefore, we conceptualized these review solicitation media on the continuum of anthropomorphism and investigated how various levels of anthropomorphism affect rating valence and review quality, showing that more anthropomorphic media lead to more positive and less helpful reviews. We showed that moderate levels of anthropomorphism lead to increased interaction enjoyment, while high levels increase social presence, thus inflating the rating valence and decreasing review helpfulness. Further, the effect of anthropomorphism is stronger for low-quality products and remains robust across review solicitor’s salience (sellers vs. platforms) and expressed emotionality in conversations. Our study is among the first to investigate chatbots as a new form of technology to solicit online reviews, providing insights to inform various stakeholders of the advantages, drawbacks and potential ethical concerns of anthropomorphic technology in customer feedback solicitation.
