On 30 July, Lara Buchak delivered the annual Jack Smart Lecture, “Taking Risks for Others”, to a large audience. Choosing for others is simple when outcomes are certain: we need only know what is best for them. However, under risk, the choice also depends on attitudes towards risk, which may vary rationally. Ordinary judgment recommends risk-averse choices when another person’s attitude is unknown, but this principle requires justification. It also raises a puzzle: why is imposing a risk without consent impermissible, while denying someone a chance of benefit may be permissible? Lara argued ingeniously that connecting other-directed choice to interpersonal distribution explains both the principle and this asymmetry, and that the two areas of ethics provide mutual support. The lecture was lucid, engaging, and thought-provoking, and prompted a lively and wide-ranging discussion.
