The present paper proposes an integrative account of social forms of practical
irrationality and corresponding disruptions of individual and group-level emotion
regulation (ER). I will especially focus on disruptions in ER by means of
collaborative agential and doxastic akrasia. I begin by distinguishing mutual,
communal and collaborative forms of akrasia. Such a taxonomy seems all the more
needed as, rather surprisingly, in the face of huge philosophical interest in
analysing the possibility, structure, and mechanisms of individual
practical irrationality, with very little exception, there are no comparable accounts
of social and collaborative cases. However, I believe that, if it is true that
individual akrasia is, in the long run, harmful for those who entertain it, this is
even more so in social contexts. I will illustrate this point by drawing on various
small group settings, and explore a number of socio-psychological mechanisms
underlying collaborative irrationality, in particular groupthink. Specifically, I
suggest that in collaborative cases there is what I call a spiraling of
practical irrationality at play. I will argue that this is typically
correlated and indeed partly due to biases in individual members’ affect
control and eventually the group’s with whom the members identify.
