Using a pilot experiment, two between-subjects experiments, and a survey, this paper investigates how individuals evaluate products differently depending on the scale used, how they categorize ratings on a 5-point scale into binary bins, and how they estimate 5-point distributions from binary scales. Individuals perceive products as higher in quality when ratings are presented on a binary scale if reviews have been assigned to positive or negative categories based on whether they are above or below the midpoint of a 5-point scale. Individuals perceive products as being of equivalent quality across scales only when ratings of four and five are taken as positive, and the remainder as negative. However, when individuals are asked to generate a 5-point distribution from binary ratings, they do not account for this skew <i>unless</i> the 5-point scale is explicitly labeled so that the “neutral” point of the scale is defined as four rather than three. These findings extend the literature that aims to understand how people evaluate products given different forms of ratings information.</p>","PeriodicalId":48112,"journal":{"name":"Journal of Behavioral Decision Making","volume":"39 2","pages":""},"PeriodicalIF":1.4,"publicationDate":"2026-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/bdm.70080","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147668271","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such help conforms with prevalent social norms and can increase collective welfare. We study how the surplus created through such help is shared by the benefactor and the beneficiary. We hypothesized that aspects of the situation, such as relative wealth, social distance, whether the help increased gains or prevented losses, and perspective may result in variations in this division. In two experiments, we compare participants' judgments (<i>N</i> = 695) and participants' bargaining choices (<i>N</i> = 617 dyads). In both tasks, the proposed compensation for the cost incurred, while the benefits of helping exceeded the cost and was affected similarly by the manipulated factors. We observed pro-social equalizing of outcomes, less indebtedness to family benefactors than to commercial ones, and sensitivity to the fact that help-seeker was suffering a loss. However, whereas the judgments allocated to the beneficiary about 80% of the surplus generated, in (consequential) minimal bargaining, the surplus was split more equally, as expected by economic theory. This gap raises doubts about the validity of using nonconsequential measures.</p>\u0000 </div>","PeriodicalId":48112,"journal":{"name":"Journal of Behavioral Decision Making","volume":"39 2","pages":""},"PeriodicalIF":1.4,"publicationDate":"2026-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147668067","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
