| Reliability | α ≈ .81 for the 16-item Sample Test |
| Link to IQ | total score correlates r ≈ .81 with WAIS-IV Full-Scale IQ (Young & Keith, 2020) |
| Original sample | average ≈ 8 / 16 in the large online study |
Why only part of it — and where the rest is
The authors of the ICAR deliberately released this 16-item Sample Test to the public, while keeping their larger item bank private to protect the test’s validity. So this isn’t a leak or a shortcut: it’s exactly the slice they chose to share. It lives here so that anyone curious — including people who can’t afford a private assessment or reach a university library — gets an honest taste and the facts they need, without a paywall. The wider project, and the figural items’ background, are at icar-project.org.
