Nonetheless, quantitative evidence about how people mentally represent and perceive strangers online is still missing. Given the dynamic development of web technologies, quantifying how much strangers can be considered suitable for pro-social acts such as self-disclosure appears fundamental for a whole series of phenomena ranging from privacy protection to fake news spreading. Using a modified and online version of the Ultimatum Game (UG), we quantified the mental representation of the stranger on the Internet effect and tested if people modify their behaviors according to the interactors\u2019 identifiability (i.e., reputation). A total of 444 adolescents took part in a 2 \u00d7 2 design experiment where reputation was set active or not for the two traditional UG tasks. We discovered that, when matched with strangers, people donate the same amount of money as if the other has a good reputation. Moreover, reputation significantly affected the donation size, the acceptance rate and the feedback decision making as well.<\/jats:p>","DOI":"10.3390\/fi13050110","type":"journal-article","created":{"date-parts":[[2021,4,27]],"date-time":"2021-04-27T21:18:20Z","timestamp":1619558300000},"page":"110","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["Reviewing Stranger on the Internet: The Role of Identifiability through \u201cReputation\u201d in Online Decision Making"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8272-9484","authenticated-orcid":false,"given":"Mirko","family":"Duradoni","sequence":"first","affiliation":[{"name":"Department of Education, Languages, Intercultures, Literatures and Psychology, University of Florence, 50135 Firenze, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stefania","family":"Collodi","sequence":"additional","affiliation":[{"name":"Department of Education, Languages, Intercultures, Literatures and Psychology, University of Florence, 50135 Firenze, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Serena Coppolino","family":"Perfumi","sequence":"additional","affiliation":[{"name":"Department of Sociology, Stockholm University, S-106 91 Stockholm, Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0203-4461","authenticated-orcid":false,"given":"Andrea","family":"Guazzini","sequence":"additional","affiliation":[{"name":"Department of Education, Languages, Intercultures, Literatures and Psychology, University of Florence, 50135 Firenze, Italy"},{"name":"Center for the Study of Complex Dynamics (CSDC), University of Florence, 50121 Firenze, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,4,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"535","DOI":"10.1016\/j.chb.2015.02.027","article-title":"Stranger on the internet: Online self-disclosure and the role of visual anonymity","volume":"48","author":"Misoch","year":"2015","journal-title":"Comput.
