Cognitive Adaptability

The exact item set behind the neuroplasticity assessment, published for audit. Every credential issued for this test is stamped with the content hash below; verify a credential to see the stamp checked live.

Public today — may be locked up at any time. These batteries are published so anyone can inspect the exact questions behind a testmyself credential. Publication is at our discretion: the batteries are public today, and we may lock them up — make them private — at any time, without notice. Locking them up would not change any credential already issued: every credential stays pinned to the battery version and content hash recorded when it was scored.
