Brian Keating describes an explicit personal algorithm he used to decide when to stop dating and commit. Instead of using wealth, status, looks, or fame as criteria, he tracked his dating history like data and applied a single test to each serious candidate: if he had a daughter with this person, would he be glad if his daughter turned out just like them? He deliberately dated a wide range of people over years, ruled out obviously wrong reasons for staying with someone (attraction alone, excitement, status), and kept going until someone passed that specific character test. The mechanism forces the decision away from in-the-moment feelings and status-signaling toward a values-based, future-oriented standard, and it gives the search a defined stopping point instead of endless comparison-shopping.
Origin
Keating, a self-described nerd and physicist, says he treated dating like data collection ('what you measure, you manage') after years of dating widely and not finding lasting fit until his mid-to-late 30s.
Core principles
- 01Track real data across your dating history instead of relying purely on in-the-moment attraction
- 02Discount status variables (wealth, looks, fame, social proof) as decision criteria
- 03Judge character by whether you'd want it replicated in your own child, not by how the relationship feels right now
- 04Set a hard stop condition in advance so the search has a defined end state
- 05Nobody ever feels fully 'ready' for commitment, so readiness can't be the trigger
How to run it
- 1
Date broadly and track the data
Go through a real dating history across different types of people and personalities rather than committing early on instinct alone.
Pro tip Treat it like an informal experiment: what you measure, you manage.
Watch out This isn't a spreadsheet exercise — the relationships still have to be real.
- 2
Strip out status variables
Deliberately discount wealth, fame, looks, and social proof as decision criteria, since these are the variables people over-weight and they don't predict long-term fit.
Watch out If your list of 'must-haves' reads like a resume, you're optimizing for the wrong outcome.

Apply the daughter test
For each serious candidate, ask: if I had a child with this person, would I be happy for my child to grow up to become them?
Pro tip Make it concrete — picture your actual future child mirroring this person's specific habits and character, not a vague ideal.
- 4
Set a hard stop condition
Decide in advance that you will stop searching only when someone passes the test, not when you feel generically 'ready.'
Watch out Waiting for total certainty is a trap — no one ever feels fully ready for marriage or kids.
- 5
Commit and re-verify over time
Once you commit, keep testing the decision against lived experience rather than re-litigating other options you passed on.
In the wild
Keating dated widely, including people chosen for shallow reasons by his own admission, before applying his daughter test consistently. He didn't marry until his mid-to-late 30s, once he met someone who clearly passed the standard.
→ Married 18+ years at the time of the interview, with children, describing the decision as the best one he ever made.
Common mistakes
Optimizing for the wrong variable
Choosing partners for wealth, status, or attraction alone rather than for character you'd want replicated in your own child leads to relationships that look good but don't hold up long-term.
Waiting to feel ready
Treating 'readiness' as a precondition for commitment stalls the decision indefinitely, since no one is ever fully ready for marriage or parenthood.
Is it for you?
Best for
People who keep dating without a clear standard for when to commit to a long-term partner.
Not ideal for
People not seeking a long-term, family-oriented relationship, since the test is built around parenthood as the reference point.
From the transcript
“Stop dating when you meet the girl whose daughter you would want to be your daughter. Not this not the super rich... not the super…”
“It means you take metrics, you know, what you manage you measure, what you measure you manage, right?”
“If I had a daughter with this woman, would I be okay if my daughter turned out to be like this woman?”
