The conventional explanation is that suicide is motivated as an escape from unresolvable psychological pain. However, despite suicide's high availability, its rates are very low (about 0.014% in the US). This speaks to high ambivalence as an essential feature of the suicidal mind.<b>Method:</b> To explicate the ambivalence of the suicidal mind, suicide has recently been framed within the active inference framework (AIF). AIF appears to be appropriate for conceptualising suicide because it is a theory of choice behaviour under uncertainty that, in suicide, cannot be resolved or, validated by experience. Moreover, AIF is based on the free-energy principle, which is proposed as a principle underwriting the very existence of sentient systems.<b>Results:</b> In this paper, we frame suicidal decision-making as the balance between the expected free energy of survival vs. suicide action policies. Based on this frame, we develop intuitions about the dynamics of suicidal decision-making. These intuitions are then proposed as guides for future research into suicidal decisions as well as suicide prevention.</p>","PeriodicalId":51277,"journal":{"name":"Cognitive Neuropsychiatry","volume":" ","pages":"1-22"},"PeriodicalIF":1.5,"publicationDate":"2025-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144081846","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
