From an evolutionary perspective, altruistic behaviour is still a bit of mystery to psychologists, especially when it comes with a hefty cost to the self and is aimed at complete strangers.
One explanation is that altruism is driven by empathy – experiencing other people’s distress the same way as, or similar to, how we experience our own.
However, others have criticized this account – most notably psychologist Paul Bloom, author of Against Empathy: The Case for Rational Compassion.
Their reasons are many, but among them is the fact that our empathy tends to be greatest for people who are most similar to us, which would argue against empathy driving the kind of altruism that involves the giver making personal sacrifices for strangers.
Hindering research into this topic is the challenge of measuring empathy objectively and devising a reliable laboratory measure of altruism (including one that overcomes most volunteers’ natural inclination to want to present themselves as morally good).
