Research on the self-serving of food has empirically ignored the role that visual consumption norms play in determining how much food we serve on different sized dinnerware. We contend that dinnerware provides a visual anchor of an appropriate fill-level, which in turn, serves as a consumption norm (Study 1). The trouble with these dinnerware-suggested consumption norms is that they vary directly with dinnerware size-Study 2 shows Chinese buffet diners with large plates served 52% more, ate 45% more, and wasted 135% more food than those with smaller plates. Moreover, education does not appear effective in reducing such biases. Even a 60-min, interactive, multimedia warning on the dangers of using large plates had seemingly no impact on 209 health conference attendees, who subsequently served nearly twice as much food when given a large buffet plate 2 hr later (Study 3). These findings suggest that people may have a visual plate-fill level-perhaps 70% full-that they anchor on when determining the appropriate consumption norm and serving themselves. Study 4 suggests that the Delboeuf illusion offers an explanation why people do not fully adjust away from this fill-level anchor and continue to be biased across a large range of dishware sizes. These findings have surprisingly wide-ranging win-win implications for the welfare of consumers as well as for food service managers, restaurateurs, packaged goods managers, and public policy officials.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-61484","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"Dyson School of Applied Economics and Management, Cornell University.","annee":"2013","mois":"12","numero":"19:4","page":"320-32","auteurs":[{"ID":1546,"post_author":"0","post_date":"2018-12-03 16:00:23","post_date_gmt":"2018-12-03 15:00:23","post_content":"","post_title":"Brian Wansink","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"brian-wansink","to_ping":"","pinged":"","post_modified":"2018-12-03 16:00:23","post_modified_gmt":"2018-12-03 15:00:23","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/brian-wansink\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":61482,"post_author":"0","post_date":"2018-12-04 08:57:52","post_date_gmt":"2018-12-04 07:57:52","post_content":"","post_title":"Koert Van Ittersum","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"koert-van-ittersum","to_ping":"","pinged":"","post_modified":"2018-12-04 08:57:52","post_modified_gmt":"2018-12-04 07:57:52","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/koert-van-ittersum\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"}],"sources":[{"ID":61483,"post_author":"0","post_date":"2018-12-04 08:57:52","post_date_gmt":"2018-12-04 07:57:52","post_content":"","post_title":"Journal of experimental psychology.
