Hi everyone, I'm Derek and the co-founder of Boo, a relation dating app powered by psychology. I made an introductory practical guide to guessing anyone's personality type based on first impressions. This is for people who aren't that familiar with MBTI/cognitive functions theory. For those who are already familiar, I'll write an advanced guide.
I blog about psychology, personality, dating, and MBTI/cognitive functions/Big 5. Can follow me on Medium to keep posted!
