Press · Science · Story

A founder the press already knows.

Jorge Cruise is a 13× New York Times bestselling author who came out publicly in 2010, founded Project 1973, and has spent the last decade reading the peer-reviewed 2D:4D digit-ratio literature — from Manning 1998 to the 2025 meta-analysis of 227,648 participants. The Ratio Tribe is the result.
