Instincts to punish people are how actual humans precommit.
i think you could equally frame this as “people precommit due to an expectation of reciprocity”. like, i don’t generally follow through on my commitments to plans with friends because i fear punishment for breaking them. it’s more that i expect whatever amount i invest into the friendship will be reciprocated (approximately).
you could frame the fallout of a commitment failure as “punishment”, but if the risk of punishment exceeded the benefit of cooperation that would discourage me from pre-committing; from interacting with the thing at all. if i thought my crush would beat me should i break things off with him, then i’d simply never ask him out to begin with and we’d probably both be worse off for that.
