David Petraeus is not your run-of-the-mill husband with a wandering eye. He's not just another philandering politician or celebrity cheater, like so many others whose indiscretions have come to light in recent years.
He's a retired Army general who designed and led the military surge in Iraq and was top commander in Afghanistan. He had been deployed much of his career until he was named CIA director last year. His abrupt resignation amid news of his affair with a married Army Reserve officer brings a new wrinkle into an old story of why yet another powerful man risks so much for a woman.
Petraeus joins the list of wayward sons: Arnold Schwarzenegger, John Edwards, Mark Sanford and Eliot Spitzer -- just to name a few.
Risk takers "tend to believe they control their destiny or fate," says Frank Farley, a psychologist at Temple University who studies such behavior. "The risk-taking personality has a bold quality. It's at the heart of great leadership, and sometimes it overrides what many Americans would call common sense."
Add in a dose of entitlement, suggests Mira Kirshenbaum, clinical director of the Chestnut Hill Institute in Boston who has written books about infidelity.
"Power and success give people a sense of invulnerability," she says. "A lot of guys like Petraeus have worked awfully hard, and, yes, they have a lot to show for it, but day-to-day mostly what they face is more hard work. Where's the big reward? An affair can seem like a long-deserved perk."
Petraeus' resignation letter, which cites "very poor judgment," is particularly troubling to Dan Crum, a former CIA polygraph examiner who is now a consultant in Fairfax, Va.
"When he said he showed poor judgment, it minimizes the affair and characterizes it more as a one-time poor decision than an extended period of decisions to maintain and continue the affair," he says. "It's almost like a 'How dare you?' response. It's part of that almost arrogance -- 'Who are you to question me? I'm the one giving the orders here.'"
Crum says the fact that there was an e-mail trail between the two "demonstrates a level of arrogance and a feeling you're above the law."
"Anybody with even the most minimal training in covering things up or keeping things secret would never have e-mails that can directly link back to you," he says.
But John Caughlin, a professor of communication at the University of Illinois-Urbana-Champaign who focuses his research on disclosure and secrecy, says there's a flip side to that argument.
"There is a sense that if somebody goes out of their way to take extreme measures to guard information -- in some ways that indicates a sense of shame," Caughlin says. "He probably knew it was wrong, but maybe not that wrong."
New research by sociologist Andrew London, a senior fellow at the Institute for Veterans and Military Families at Syracuse University in New York, has found an increased incidence of extramarital sex among veterans. One study online in the Journal of Family Issues used 1992 data from 2,308 people who have ever been married to find that more than 32% of veterans reported extramarital sex -- about twice the rate among ever-married non-veterans.
A follow-up that includes data from 2010 finds "elevated odds for extramarital sex were higher among both male and female veterans," he says. London, the lead author, also finds that those who served in the military four years or longer had particularly elevated odds.
"We argue there could be things that predate military service -- like being a risk taker -- that might lead someone into the military but also increase their likelihood of taking a risk while married and having an extramarital affair," he says.
Cregg Chandler of Sumter, S.C., has seen it firsthand. He retired in 2007 after 29 years in the Air Force, including the last nine as a chaplain. He says infidelity appears to have escalated. That's why he wrote A Separation Survival Guide for Military Couples, out earlier this year: He says military life often brings stress, isolation and frustration, which can lead to infidelity.
Military separations, which are recurring and often long-term, create loneliness without the family support system.
"They have a saying in the military -- 'What happens TDY (temporary duty assignment) stays TDY.' I'm not saying it's an overall mentality, but they have that saying."
