Take the broad screen

Six short screeners, back to back, as one set of questions — about ten minutes. We don’t name what each part measures until the end, so the label of a test can’t bias how you answer. You get a single read-out: where your answers point, what each signal could also mean, and what’s worth reading more about.

Why these tests are grouped by the brain mechanism underneath rather than by diagnostic label — the guessing-machine idea, the five dials, and the look-alikes that change what actually helps. Plain language, with a couple of diagrams.

another way in

A few short, interactive walk-throughs — less a questionnaire, more a guided look at how one kind of thinking actually works, built around a quick exercise and an example of your own. About five minutes each; like everything here, nothing you enter is saved.
