Personal Identity, Self Connectedness, and Time-Biases

Empirical evidence suggests that one explanation for a certain sort of time-bias—near-bias—is diminution in self-connectedness between current person-stages and temporally farther future stages. In this paper we extend this research in two directions. First, we explore the association between self-connectedness towards past person-stages and retrospective near-bias, with the aim of determining whether we can explain retrospective near-bias in terms of diminished feelings of connectedness between current person-stages and temporally farther past stages. Second, we explore the association between future-bias and asymmetries in self-connectedness with future stages as compared with equidistant past stages. If current stages feel more connected to future stages than equidistant past ones, then this asymmetry could explain our bias towards future over past person-stages. We aim to determine whether this is so, in part as a way to try and better understand the mechanisms that underlie time-biases, but also in order to better evaluate the normative status of these preferences. That is because on many views, the strength of certain inter-stage connections grounds there being an egoistic concern relation obtaining between stages, whose strength, in turn, determines whether that stage has prudential reason to have (or not) time-biased preferences. Since self-connectedness may be evidence of, or partly constitutive of, such inter-stage connections, it may be that if asymmetries in, or diminution of, self-connectedness, explains time-biased preferences, it also normatively licenses those preferences.
