Contrary to the common belief that divorce rates are at an all-time high, they actually peaked around 1980 when roughly half of all marriages ended in divorce. Since that peak, the rate has been on a steady, multi-decade decline and is now considerably lower.

Stable marriage is increasingly correlated with high income. While 75% of men in the top income quintile marry, only 25% in the bottom quintile do. This reframes the decline of marriage not as a cultural choice, but as a clear marker of economic class division.

Contrary to the narrative that rising singlehood is purely a choice of freedom, surveys show that 60% to 70% of single people would rather be in a relationship. This indicates that for many, being single is an undesirable outcome of current social and dating market dynamics, not a celebration of independence.

Contrary to common advice, high expectations aren't inherently bad for marriage. They create a bifurcation: couples who invest enough to meet these expectations achieve unprecedented levels of fulfillment, while those who can't are often unhappier than couples from past eras with lower expectations.

The decline in the US marriage rate is driven more by age at first marriage than by a rejection of the institution. While the percentage of people who will ever marry has only slightly decreased, the average time a person spends married in their lifetime is much lower because they are marrying later than ever before.

Because women traditionally 'mate up' socioeconomically, the falling economic and educational status of men has shrunk the pool of 'eligible' partners.

Contrary to the "get it out of your system" theory, a higher number of past sexual partners is a strong predictor of future relationship instability. For both men and women, it correlates with higher rates of divorce, cheating, and lower satisfaction in long-term relationships.

Marriage is no longer a universal institution but a strong indicator of economic status. Three-quarters of men in the top income quintile will marry, compared to only one-quarter in the lowest quintile, making stable partnership a modern Veblen good.

The introduction of no-fault divorce laws was a legislative response to already-spiking divorce rates that were overwhelming the court system, rather than the cause of the increase. Data from states like California shows divorce rates were already rising before the law was changed and simply continued on the same trajectory afterward.

The success of a long-term relationship is better predicted by how partners handle conflict and disagreement than by how much they enjoy good times together. People are more likely to break up due to poor conflict resolution than a lack of peak experiences.

Despite social progress, a man's identity remains deeply tied to his economic status. When a woman in a relationship earns more than her male partner, the likelihood of divorce doubles, and his use of erectile dysfunction medication triples. This reveals a persistent and powerful link between masculinity, money, and relationship stability.
