Guard against temptation: Intrapersonal team reasoning and the role of intentions in exercising willpower

Sometimes we make a decision about an action will undertake later and form intention, but our judgment of what it is best to do undergoes temporary shift when the time for comes round. What makes rational not give in temptation? Many contemporary solutions privilege diachronic rationality; some “rational non-reconsideration” (RNR) accounts once agent forms reconsider. This leads other puzzles: how can someone be motivated follow plan that contrary their current judgment? How resist if predict shift? I show these puzzles solved framework where there are multiple units agency, distinguishing between judgments timeslice those person over time, allowing “self identify”, taking as relevant unit agency doing intrapersonal team reasoning (with different causal role intentions than RNR accounts). On my account, resisting temptation compatible with synchronic rationality, so rationality aligned. However, either or succumbing instrumentally rational, depending on identified with. In order why ought temptation, need draw non-instrumental rationale. sketch possible routes this.
