The Three Six Rule: How Rare Is a 6-6-6 Man?
Three Six Mafia – Data about "6/6/6 dating" (2024)

A humorous data-driven analysis of the 'Three Six Rule'—the dating standard requiring men to be 6 feet tall, have a 6-inch penis, and earn a 6-figure salary. Using statistical distributions for height, penis length, and income, the author calculates that only 0.425% of men meet all three criteria. He then explores trade-offs between these attributes, showing how a larger penis can compensate for shorter height, and vice versa, with charts and formulas.
In a gaggle of 100 suitors, it's actually unlikely that a single one will meet all three criteria. Perfection.

Also of note the income data is combined household income (2 incomes for a married couple) and over the entire population (including 40+ later-career incomes).
It's likely significantly over predicting how common $100k yearly income is among the 20-35 year old "dating pool". Though probably balanced out some by being 10 year old data by now.

The information that was missing from my life:
For the Average Man, gaining an inch of height is worth losing roughly $25k in annual salary. Meanwhile, an inch of pecker is roughly offset by reducing annual salary by $128k.

This is solid reporting:
> A 6" wiener is even rarer than being 6' tall. The average erect penis length is 5.166" with a std dev of 0.654".

I really thought this post was gonna be adjacent to the hip-hop group, and I was patiently waiting to be told that Poppin one's Collar accounts for a pecker deficit.

And here I was shocked and really happy to hear about Three 6 Mafia on HN.
Fun fact: Three 6 Mafia used to be Triple 6 Mafia, they changed their name to be "radio friendly" (Three Six Mafia rolls off easier than Triple Six Mafia) after signing a record deal.

Putting on my atheist hat for a minute, I think these statistics are interesting in reminding people that there is an underlying biological and evolutionary process underlying mate selection. You’re being evaluated for biological fitness criteria.
That said, individual chemistry is highly variable so these particular criteria are just a proxy and negotiable. Don’t take stated criteria at face value. My now wife’s type was chubby 6-foot plus midwestern future lawyers. But then she met a 5-9 Bangladeshi in law school and got baby fever and that was that. My personal view of it is God has a plan for all of us, but if you’re an atheist you can see it as the chemistry of biological compatibility being highly complex and individualized.

These variables are not independent so you can't just multiply ratios to get combined ratio.
(If height were not correlated with income that would be surprising, for example.)

The three six rule is a low bar for dating: you should also have a 6 pack. If you only want three sixes, here are 666 cents I keep in my pocket!
