On Feb 14, 2024, the discussion in the Three Six Mafia chat turned to the Three Six Rule, the idea that a date‑able guy must score a 6 in income, height and penis length. The author, married, wonders if a partner can compensate for a shortfall in one area by excelling in another, and whether the rule truly filters the dating pool.

In the U.S., men 20‑30 average 70" with σ = 3, placing a 6' (72") at the 75th percentile—75% of men are shorter. Penis length averages 5.166" (σ = 0.654), so a 6" reaches the 90th percentile, leaving only 10% above that mark. Treating height and length as independent, the joint exclusivity for both is about 2.5%.

A 6‑figure salary, based on 2014 log‑normal data (μ = 10.8, σ = 0.758), gives an exclusivity of about 17% for $100 k. Multiplying height, length and salary exclusivities yields an overall Blended Exclusivity Score of 0.425%—less than 1 in 200 men meet all three criteria. The author then muses whether a higher income could offset a shorter stature or smaller penis, and how the rule might be adapted.
