The claim
Batson’s empathy–altruism hypothesis: feeling empathic concern for a person in need evokes a motive whose ultimate goal is that person’s welfare, not one’s own. Against Cialdini et al. (LIT-1728), Batson et al. (LIT-1700) report that the empathy–helping link holds with perceived self–other merging controlled. If so, the owner’s thesis (CLAIM-491) fails for at least some helping: there is no extended self for the motive to serve.
What it does not say
- Not that most helping is altruistic. One altruistic motive is enough to defeat a universal thesis.
- Not that the 1997 exchange is settled. Cialdini et al. measured oneness differently. Which measure captures the self’s extent is the crux that QUESTION-300 asks about.
Note of 2026-10-29: the SEP’s report
Doris, Stich, Walmsley and Schulz (NOTE-1274) report that Batson et al. found methodological problems in Cialdini et al. and, in “a pair of experiments” that avoided them, found empathy’s role in helping “clearly evident”. They give no numbers, and the paper is still unread; the summary above now leaves the count to the SEP. They argue that none of the four merging measures in the exchange (IOS, “we”, perceived similarity, a trait-rating difference) tests for perceived numerical identity. On their view only that would make helping egoistic, so neither side measured what egoism needs. The owner’s thesis claims less than identity, an extended self-identification, so the argument leaves it open. It does put the thesis to saying why such a self counts as the agent’s own.
Note of 2026-10-30: what holds it back
Its evidence, Batson et al. 1997 (LIT-1700), is Unavailable and known only from the SEP’s report (NOTE-1274), which gives no numbers. The paper it answers, Cialdini et al. (LIT-1728), is now read (NOTE-1444) and cuts against it: with oneness controlled, empathic concern predicted no willingness to help in any of twelve relationship conditions, near strangers included. That weighs against the objection without defeating it, because the helping was imagined and the reply criticised that paradigm. What would settle it is a read result, the reply or a later study, in which empathic concern predicts real helping with oneness measured as Cialdini et al. measured it.
