All three versions score the same twelve axes. Longer versions add statements per axis from both directions, which matters most when two ideologies land close together on your vector. You can change version later without losing the answers you have already given.
Before you startAnswer as yourself, not as you would like to be. There is a genuine neutral option, and a skip if a statement does not apply to you.Answers you skip are not counted on that axis at all, so skipping never shifts a score.Keyboard: press 1–5 to answer, or use ← and → to move between statements.
