Leveraging the dynamic geometric principles associated with the mathematics of quantum theory, we use the idea of probability interference to explain projection bias and its violations of the classical law of total probability and expected utility theory. In particular, Khrennikov\u2019s contextual probability model is successfully applied to the study by Read &amp; van Leeuwen on hunger and projection bias. We conclude that probability interference provides an effective, accurate and meaningful way to model projection bias, thus broadening the reach of quantum cognition in economics.<\/jats:p>\n                  <jats:p>This article is part of the theme issue \u2018Quantum theory and topology in models of decision making (Part 1)\u2019.<\/jats:p>","DOI":"10.1098\/rsta.2024.0558","type":"journal-article","created":{"date-parts":[[2025,11,27]],"date-time":"2025-11-27T08:06:23Z","timestamp":1764230783000},"update-policy":"https:\/\/doi.org\/10.1098\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Quantum cognition and projection bias"],"prefix":"10.1098","volume":"383","author":[{"ORCID":"https:\/\/orcid.org\/0009-0007-6224-4202","authenticated-orcid":true,"given":"Raymond","family":"Hawkins","sequence":"first","affiliation":[{"name":"Wyant College of Optical Sciences, University of Arizona, Tucson, AZ 85721-0094, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Evan","family":"Walsh","sequence":"additional","affiliation":[{"name":"Wyant College of Optical Sciences, University of Arizona, Tucson, AZ 85721-0094, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"175","published-online":{"date-parts":[[2025,11,27]]},"reference":[{"key":"e_1_3_8_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhealeco.2007.01.002"},{"key":"e_1_3_8_3_2","doi-asserted-by":"publisher","DOI":"10.1257\/aer.97.4.1217"},{"key":"e_1_3_8_4_2","doi-asserted-by":"publisher","DOI":"10.1162\/003355303322552784"},{"key":"e_1_3_8_5_2","volume-title":"Models of man, social and rational: mathematical essays on rational human behavior in a social setting","author":"Simon H","year":"1957","unstructured":"Simon H. 1957 Models of man, social and rational: mathematical essays on rational human behavior in a social setting.
