How to get the most from it

Moral Machine sits in Personality Tests under Play, filed as coffee break.

  • Set aside five to fifteen minutes and give it your proper attention.
  • It works on a phone or a desktop, so open it on whatever is nearest.
  • It works with the sound off, so it is fine on a train or in a quiet office.
  • No account needed — you can start without signing up.
  • Go in expecting something unsettling and brainy.

About this category: Typologies, moral dilemmas, purity scores and which-character quizzes. Somewhere between genuine psychometrics and a magazine back page, and both ends are entertaining.
