More strawman arguments. Please stop resorting to fallacies.
Excellent, now we can get started.
The study they got that data from (McCoy, Shawn P., and Michael G. Aamodt. “A comparison of law enforcement divorce rates with those of other occupations.” Journal of Police and Criminal Psychology 25.1 (2010): 1-16.) was, as the title suggests, intended to show that law enforcement don’t have unusually high divorce rates.
The study used simple, raw statistics and a basic formula: (Separated + Divorsed) / (Total Population - Never Married) [sic]
They did not control for any factors at all. However, they did note one important thing, and that is the possible relevance of “the personality of the people who enter the profession” (they go between asking “whether it’s the nature of the jobs that lead to divorce, or if people prone to unstable relationships are drawn to certain professions”). That’s important, as it turns out.
But first: you will notice that the occupations with the lowest levels of divorce are either religious or male-dominated (along with fields related to them). In fact, some occupations (e.g. transit and railroad police, agricultural engineers) do not have statistics on women in their fields because there are so few (e.g. ~0). This is worth noting: gender ratios are important.
For example:
(From: McKinnish, Terra G. “Occupation, sex-integration, and divorce.” The American Economic Review 94.2 (2004): 322-325. - see also: Svarer, Michael. “Working Late Do Workplace Sex Ratios Affect Partnership Formation and Dissolution?” Journal of Human Resources 42.3 (2007): 582-595.)
It seems reasonable to point out that some of the occupations with the highest levels of divorce also interact with the most people, and in ‘interesting’ environments.
Now, you ignored my previous mentioning of selectivity, so you should
probably go (re-)read it.
Back to personality:
“[a person’s] occupation reliably relates to features of personality (Myers & McCaulley, 1985).” It also relates to extraversion, lack of constraint, and sociosexuality (Gangestad, Steven W., and Jeffry A. Simpson. “Toward an evolutionary history of female sociosexual variation.” Journal of Personality 58.1 (1990): 69-96). Sociosexuality has a direct link with divorce risk (e.g.: Seal, David Wyatt, Gina Agostinelli, and Charlotte A. Hannett. “Extradyadic romantic involvement: Moderating effects of sociosexuality and gender.” Sex Roles 31.1-2 (1994): 1-22., Barta, William D., and Susan M. Kiene. “Motivations for infidelity in heterosexual dating couples: The roles of gender, personality differences, and sociosexual orientation.” Journal of Social and Personal Relationships 22.3 (2005): 339-360., etc).
The connections are noted between all of these things: “Personality influences the essential choices we make in life including choice of partner, education and career (Marrs, Barb, and Ruggiero 2007; Page, Bruch, and Haase 2002; Wilke et al. 2006)” (Vuust, Peter, et al. “Personality influences career choice: Sensation seeking in professional musicians.” Music Education Research 12.2 (2010): 219-230).
So, “boredom susceptibility” and “sensation seeking” affects both career and marriage (Wilke, A., J.M.C. Hutchinson, P.M. Todd, and D. Kruger. Is risk taking used as a cue in mate choice? (2006): Evolutionary Psychology 4: 367-93). Personality is genetically influenced - not surprisingly, divorce is substantially genetically mediated (nearly 60% heritable) (e.g.: Jocklin, Victor, Matt McGue, and David T. Lykken. “Personality and divorce: a genetic analysis.” Journal of personality and social psychology 71.2 (1996): 288., Johnson, Wendy, et al. “Marriage and personality: a genetic analysis.” Journal of Personality and Social Psychology 86.2 (2004): 285).
Unsurprisingly, personality disorders also correlated with lower educational attainment and higher divorce (Ettner, Susan L., Johanna Catherine Maclean, and Michael T. French. “Does having a dysfunctional personality hurt your career? Axis II personality disorders and labor market outcomes.” Industrial Relations: A Journal of Economy and Society 50.1 (2011): 149-173., Grant, Bridget F., et al. “Prevalence, correlates, and disability of personality disorders in the United States: results from the National Epidemiologic Survey on Alcohol and Related Conditions.” Journal of Clinical Psychiatry (2004)., etc).
