Why this exists
Most online personality tests are either thinly-disguised knock-offs of NEO-FFI / MBTI / 16PF, or BuzzFeed-grade quizzes with no scientific basis. This lab is neither. Every instrument used here is public domain or Creative Commons, with the original citation, license, and source URL on every page.
Mani is a senior product leader and 2X founder pursuing an MA in Psychology at IGNOU. The lab is part of his work applying behavioral psychology to product design and team building.
