Since a partner of a social interaction often changes, an individual should assess his partner by using social information such as reputation and make decisions whether to help him or not. To those who have `good\u0027 social reputation does a player give aid as reciprocation, whereas he has to refuse to help those who have `bad\u0027 reputation. Otherwise benefits of altruism is easily exploited by them. Little has been known, however, about the definition of `goodness\u0027 in reputation. What kind of actions are and should be regarded as good and what kind of actions bad? And what sort of goodness enables sustaining exchange of altruism? We herein challenge this question with an evolutionary perspective. We generalize social reputation as `Honor-score\u0027 (H-score) and examine the conditions under which individuals in a group stably maintain cooperative relationships based on indirect reciprocity. We examine the condition for evolutionarily stable strategies (ESSs) over 4096 possible cases exhaustively. Mathematical analysis reveals that only eight cases called `leading eight\u0027 are crucial to the evolution of indirect reciprocity. Each in the leading eight shares two common characteristics: (i) cooperation with good persons is regarded as good while defection against them is regarded as bad, and (ii) defection against bad persons should be regarded as a good behavior because it works as sanction. Our results give one solution to the definition of goodness from an evolutionary viewpoint. In addition, we believe that the formalism of reputation dynamics gives general insights into the way social information is generated, handled, and transmitted in animal societies.", "subitem_description_type": "Abstract"}]}, "item_10001_publisher_8": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "Elsevier "}]}, "item_10001_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_name": [{"subitem_relation_name_text": "10.1016/j.jtbi.2004.06.005"}], "subitem_relation_type_id": {"subitem_relation_type_id_text": "http://doi.org/10.1016/j.jtbi.2004.06.005", "subitem_relation_type_select": "DOI"}}]}, "item_10001_rights_15": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "© 2004 Elsevier Ltd."}]}, "item_10001_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "00225193", "subitem_source_identifier_type": "ISSN"}]}, "item_access_right": {"attribute_name": "アクセス権", "attribute_value_mlt": [{"subitem_access_right": "metadata only access", "subitem_access_right_uri": "http://purl.org/coar/access_right/c_14cb"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "OHTSUKI, Hisashi"}], "nameIdentifiers": [{"nameIdentifier": "770", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "IWASA, Yoh "}], "nameIdentifiers": [{"nameIdentifier": "1547", "nameIdentifierScheme": "WEKO"}]}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "資源タイプ", "attribute_value_mlt": [{"resourcetype": "journal article", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "How should we define goodness? - reputation dynamics in indirect reciprocity", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "How should we define goodness? - reputation dynamics in indirect reciprocity"}, {"subitem_title": "How should we define goodness? - reputation dynamics in indirect reciprocity", "subitem_title_language": "en"}]}, "item_type_id": "10001", "owner": "21", "path": ["279"], "permalink_uri": "https://ir.soken.ac.jp/records/3665", "pubdate": {"attribute_name": "公開日", "attribute_value": "2013-06-27"}, "publish_date": "2013-06-27", "publish_status": "0", "recid": "3665", "relation": {}, "relation_version_is_last": true, "title": ["How should we define goodness? - reputation dynamics in indirect reciprocity"], "weko_shared_id": 21}
