№ 03 Original research
We don't just cite the data. We collect it.
Every quarter we survey a representative panel of U.S. adults about mental health, sleep, and stress — then publish the full dataset for anyone to use. Journalists, researchers, and the curious: it's yours.

№ 04 Medical review
Built on validated instruments, reviewed by clinicians
Every screening here reproduces a published, validated clinical instrument — the PHQ-9, GAD-7, ASRS, AQ-10, OCI-R — with its scoring intact. We are assembling an independent medical review board to sign off on every tool; until each is reviewed, we say so plainly on the page rather than imply an endorsement that isn't there yet.
