Let's say Bob publishes an analysis of suicide methods meant to assist those so inclined. Alice takes Bob at his authoritative word and follows his advice to the letter regarding the method he deems as the most foolproof. However, it fails to take, and Alice winds up with serious injuries and a permanent disability. She seeks to sue Bob for his dangerous (or rather, not-dangerous-enough) advice. Would she be likely to win such a lawsuit? Does the suffering of injury when you were seeking death constitute an adverse outcome, legally speaking? Say the lawsuit was to take place in the US, for concreteness.
Moreover, would it affect the lawsuit if it came to light that Bob knowingly published falsehoods and incorrect advice, as a last-ditch effort to spare the lives of would-be suicide victims like Alice? It can be assumed that Bob had sufficient exhortations to seek professional help at the start of his publication.
