Web of Belief vs. “What religion / philosophy are you?” quizzes
them — Quizzes like Belief-O-Matic or political-compass-style tests sort you into a labelled bucket — a religion, an -ism, a quadrant — by scoring your answers against a key.
web of belief — Web of Belief never labels you. It doesn't place you on a spectrum or tell you what you “are.” It only reports relationships between specific statements you affirmed, and leaves the conclusions to you.
If you want a quick, fun identity label, those quizzes are the better choice. If you want to examine whether your stated beliefs hold together, that's this.
