Three Six Mafia – Data about "6/6/6 dating" (2024)

📝 Discussion Summary (Click to expand)

Three dominant themes

Theme Summary Representative quote
1. The “6‑6‑6” rule – height, penis size & earnings Many participants reference the click‑bait claim that a man needs to be 6 ft tall, have a 6‑inch penis and earn $6 k/month to be “dateable.” The discussion treats it as a shorthand for how society quantifies male desirability in terms of money, stature and size. “For the Average Man, gaining an inch of height is worth losing roughly $25k in annual salary.” — 0-_-0
2. Evolutionary / biological rationale for height preference Several commenters argue that taller stature is subconsciously linked to perceived dominance, protection and “evolved intuition.” This explains why height repeatedly surfaces as a mate‑selection cue across cultures. “The answer is ‘evolved intuition’, like it or not.” — hackyhacky
3. Skepticism of the underlying data & methodology A recurring critique is that the statistics are dubious—opt‑in, outdated, or conflating household vs. individual income—so any derived ratios should be taken with a grain of salt. “All such data is a little dubious, as it's pretty much always opt‑in, and there’d always be a question of whether you have a fair sample.” — rsynnott
