15 hard questions. No tricks, no traps, no look-alike answers — the difficulty is in the thinking. An IQ-style estimate, not a clinical score.
One plain note before you start: when you finish, one anonymous result is sent to the house's own stats counter — your score, and which of the 15 questions you got right or wrong. No name, no account, no identifier of any kind. It's how this test gets measured — and, in time, normed against real takers instead of assumptions.
This is an estimate from 15 hard questions; a clinical IQ only comes from a full professional test. Treat the number as a rough reading of how this set went — not a clinical score.
What you picked, what was right, and the thinking that gets there.
