Well, per LSLGuy’s recent post, more data is probably helpful.
“Amato and Previti (2003) found that when divorced individuals were asked open-endedly to provide their reasons for divorce, the most cited reasons were infidelity (21.6%), incompatibility (19.2%), and drinking or drug use (10.6%). A statewide survey in Oklahoma found that the most commonly checked reasons for divorce from a list of choices were lack of commitment (85%), too much conflict or arguing (61%), and/or infidelity or extramarital affairs (58%; C. A. Johnson et al., 2001)”
(Reasons for Divorce and Recollections of Premarital Intervention: Implications for Improving Relationship Education - PMC)
So the top reasons seem to be:
- Lack of commitment
- Infidelity
- Too much conflict / arguing
- Drinking or drug use
- Incompatibility
I would chalk pretty much every one of those in the “the marriage was probably net miserable” column, what about you? I would argue it is at least supportive, if not conclusive, to my lemma that most divorces happen due to net misery.
Then to my other supposition that LTR’s are easier to break apart than marriages, and that this is the source of their value. I already provided a cite that even for those with children, people in LTR’s split at 3x the rate as the same age cohort with children who were married. Here’s more:
"As technological changes in the home and workplace reduced the gains from specialization, the value of commitment decreased. Cohabitation, with lower exit costs than marriage, allows individuals to realize many of the gains from co-residence with less commitment.
…
Cohabitating unions tend to be much less stable than marriages for all education groups. The median duration of cohabitations is somewhat longer for the less-educated (22–24 months) than for college graduates (17 months), but is extremely short compared to marriage.
…
Economic models of marriage and cohabitation have emphasized one key difference: the costs of dissolution are much higher for marriage than for cohabitation (Brien, Lillard and Stern 2006, Matouschek and Rasul 2008). Ending a marriage involves legal formalities to divide property and debt and, if there are children, to establish custody, visitation, and support arrangements. Divorce became less costly as states adopted no fault or unilateral divorce laws starting in the 1970s, but divorce remains a complicated, uncertain, and often expensive process in both time and money. Unlike marriages, cohabiting unions can be ended simply and quickly outside of the legal system."
Which all seem directly in line with what I’ve been arguing. It is, of course, difficult to get hard, statistically valid numbers of exactly the cuts that may support your point. This is sociology. There will always be confounding variables and exceptions. But I would argue the preponderance of evidence is on my side.
Most marriages probably do end due to net misery. Most marriages do end, or are miserable.
LTR’s actually ARE easier to exit, and indeed in practice are exited faster than and with less hassle than marriages, reducing overall misery-years vs marriage.
Those are the underlying assumptions in what I’ve been arguing, and the preponderance of evidence suggests those assumptions are correct.
I look forward to cites supporting your views if you disagree.
