Our aim was to understand better how people judge the acceptability of physician-assisted suicide (PAS). We found that, for people in France of all ages and for elderly people with life-threatening illnesses, acceptability is an additive combination of the number of requests for PAS, the patient's age, the amount of physical suffering, and the degree of curability of the illness, not only when judging for hypothetical patients, but also for their spouses and for themselves. PAS can be highly acceptable to people even when the patient does not satisfy all the criteria of legislation about PAS.
