Paul Slovic shows a hard truth: our empathy doesn’t scale. We care deeply about one life, but as numbers rise, compassion fades and costs dominate attention. “Psychic numbing” isn’t a data problem but a human one.

Dark patterns aren’t UX trivia. They’re deliberate design moves that steer people toward choices they wouldn’t make on their own. New Dark Patterns Auditing Framework shows how platforms create friction: detours, endless loops, “easy” shortcuts, and forced actions.
