humanbehaviour.app Observed source

Editorial interest 74/100 Selection signal · not a rating of the site

A social game where players choose between paired photos and try to predict the preferences of a later audience.

Landing page captured for the 2026-09-13 issue.

Field notes

The system uses several distinct scoring layers: player prediction accuracy, account Elo, per-game Elo, and a separate ranking for the submitted photos. It describes two participation formats, including Collabs, where two people contribute one pairing. AI-generated examples are available for a preliminary comparison, while fictional starter entries are reserved for testing and do not affect real rankings, reviews, or credits.
