I have determined a new Reinin Dichotomy through my own empirical observations and research. I personally tested over 500 friends in Socionics, MBTI, Enneagram, and supplemented in VI to verify my hypothesis, which can now safely be considered the Truth.
Tea: Alpha and Delta Quadra
Coffee: Beta and Gamma Quadra
Any and all who insist that I am in error, clearly knows nothing of Socionics or is an idiot from a -quadra (often they are the same thing).
