A tongue-in-cheek statistical post quantifies how the “Three-Six Rule” (6-figure income, 6 ft height, 6 in penis) filters the US male dating pool.
The piece shows how simple normal-distribution assumptions and independence can shrink a candidate set to a few percent, a caution for engineers designing matchmaking or demographic filters. It also highlights the risk of using arbitrary cut-offs and ignoring correlations, which can lead to biased or unusable results in production systems.

A 6-foot height is about the 75th percentile for US men aged 20-30 (μ = 70", σ = 3").
A 6-inch erect penis is roughly the 90th percentile (μ = 5.166", σ = 0.654").
Treating height and penis size as independent yields a combined “exclusivity” of about 2.5 % of the population.
