Saad frames partner choice as one of the two highest-leverage happiness decisions (alongside profession), because your spouse bookends every single day. Against the folk maxim that opposites attract, the evidence favours assortative mating: birds of a feather flock together predicts long-term success. The key is what you assort on. Matching eye colour or shared literature is trivial; what matters is congruence on foundational values, belief systems, drive, humour, and culture. A devout partner and a caustic atheist may share chemistry yet carry a widening fissure. His own marriage to a fellow Lebanese meant identical cultural compass points, shared humour, and easy self-deprecation, which he cites as a recipe for happiness. The method offers a statistical edge, not a guarantee, like not smoking lowers but never eliminates cancer risk.
Origin
Saad draws on the evolutionary-psychology concept of assortative mating, contrasting it with the 'opposites attract' folk maxim, illustrated through his own 23-year marriage.
Core principles
- 01For lasting unions, birds of a feather beats opposites attract
- 02Assort on foundational values, not eye colour or shared hobbies
- 03Congruent worldview, humour, and culture compound daily happiness
- 04One of the two biggest happiness levers is choosing the right partner
How to run it
- 1
Name your foundational values
Get explicit about the beliefs and values that actually guide your day-to-day life, such as faith or its absence, ambition, and cultural norms.
Watch out Do not confuse foundational values with surface preferences like shared taste in music or films.
- 2
Evaluate the partner on those values
Assess congruence on the foundational axes rather than letting chemistry or physical attraction dominate the judgment.
Pro tip Religion or metaphysics, level of drive, and political orientation are high-signal because so much else flows downstream from them.
- 3
Look for the fissure
Where a core value clashes, flag it as a likely future fault line even if attraction and rapport are currently strong.
Watch out Great chemistry plus a deep values mismatch (the devout-plus-atheist case) predicts trouble, not an exception to the rule.
- 4
Weight shared culture and humour
Treat aligned cultural reference points and a shared sense of humour as genuine compatibility signal, not fluff.
Pro tip Shared culture lets small daily moments (a joke, a ritual) land instead of causing friction.
- 5
Decide as a probability, not a guarantee
Commit knowing the method raises your odds of a happy union without promising a specific outcome, and that this is one of your two biggest happiness levers.
Watch out Population-level statistics do not predict any single couple; individual exceptions do not invalidate the edge.
In the wild
On first meeting his future wife's Lebanese parents, Saad played backgammon with her father and joked, 'if I win, I get to keep your daughter.' Because they shared cultural compass points, the father understood the humour rather than taking offence. Saad contrasts this with a differently-acculturated family that might have read it as patriarchal.
→ Congruent culture and humour turned a risky first-meeting moment into rapport, illustrating value-matching in practice.
Saad's counter-example: a deeply religious person whose every daily action is guided by faith pairs with someone who thinks it's all bullshit. They may share great chemistry and love the same literature, but the foundational values fissure is already visible and likely to widen.
→ Surface compatibility cannot compensate for a core-values mismatch, which forecasts long-term conflict.
Common mistakes
Believing opposites attract
For durable unions the evidence favours similarity; betting on complementary opposites lowers the odds of long-term success.
Assorting on trivial traits
Matching on looks, hobbies, or shared media feels like compatibility but does not carry a relationship the way shared foundational values do.
Letting chemistry override a values clash
Strong attraction can mask a core mismatch, so people ignore an obvious fissure until it becomes a fault line.
Is it for you?
Best for
Anyone selecting a long-term partner who wants to raise the statistical odds of a happy, durable union.
Not ideal for
Short-term relationships, or anyone expecting a guaranteed formula rather than a probabilistic edge.
