These ratings commonly take the form of either non-personalized, aggregate product ratings (i.e., the average rating a product received from a number of consumers such as \u201cthe average rating is 4.5\/5 based on 100 reviews\u201d), or personalized predicted preference ratings for a product (i.e., recommender-system-generated predictions for a consumer\u2019s rating of a product such as \u201cwe think you\u2019d rate this product 4.5\/5\u201d). Ratings in either format can provide decision aid to the consumer, but the two formats convey different types of product quality information and operate with different psychological mechanisms. Prior research has indicated that each recommendation type can significantly affect consumer\u2019s post-experience preference ratings, constituting a judgmental bias, but has not compared the effects of these two common product-rating formats. Using a laboratory experiment, we show that aggregate ratings and personalized recommendations create similar biases on post-experience preference ratings when shown separately. Shown together, there is no cumulative increase in the effect. Instead, personalized recommendations tend to dominate. Our findings can help retailers determine how to use these different types of product ratings to most effectively serve their customers. Additionally, these results help to educate the consumer on how product-rating displays influence their stated preferences.<\/jats:p>","DOI":"10.25300\/misq\/2022\/16301","type":"journal-article","created":{"date-parts":[[2022,5,5]],"date-time":"2022-05-05T12:49:13Z","timestamp":1651754953000},"page":"627-644","source":"Crossref","is-referenced-by-count":26,"title":["Effects of Personalized Recommendations Versus Aggregate Ratings on Post-Consumption Preference Responses"],"prefix":"10.25300","volume":"46","author":[{"given":"Gediminas","family":"Adomavicius","sequence":"first","affiliation":[{"name":"Information and Decision Sciences, Carlson School of Management, University of Minnesota, 321 19th Avenue South, Minneapolis, MN 55455 U.S.A."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jesse C.","family":"Bockstedt","sequence":"additional","affiliation":[{"name":"Information Systems and Operations Management, Goizueta Business School, Emory University, 1300 Clifton Road, Atlanta, GA 30322 U.S.A."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shawn P.","family":"Curley","sequence":"additional","affiliation":[{"name":"Information and Decision Sciences, Carlson School of Management, University of Minnesota, 321 19th Avenue South, Minneapolis, MN 55455 U.S.A."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jingjing","family":"Zhang","sequence":"additional","affiliation":[{"name":"Operations and Decision Technologies, Kelley School of Business, Indiana University, 1309 East Tenth Street, Bloomington, IN 47405 U.S.A."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"10933","published-online":{"date-parts":[[2022,3,1]]},"reference":[{"issue":"4","key":"2026021717065826500_b1-19_16301_rn_adomaviciuszhang","doi-asserted-by":"crossref","first-page":"956","DOI":"10.1287\/isre.2013.0497","article-title":"Do Recommender Systems Manipulate Consumer Preferences?
