In yet another triumph of Science™, a remarkably large group of researchers has discovered that it’s a bummer when your candidate loses a presidential election:

While past studies have shown that men’s testosterone levels differentially change in response to winning or losing an interpersonal dominance contest, the present study provides novel evidence showing that vicarious victory and defeat via democratic elections has similar physiological consequences for male voters as do interpersonal dominance contests.

Basically, the researchers asked a bunch of undergrads to collect saliva samples throughout the evening of November 4 (“participants used a stick of sugar-free chewing gum to facilitate collecting up to 7.5 mL of saliva in a sterile polypropylene vial and discarded the gum,” in case you’re interested).  The chart on the right shows what happened: after 8 pm, when John McCain’s fate was sealed, testosterone levels among men who supported him plummeted.  Among women, nothing happened.

Put this together with the capuchin monkey experiment (which, sadly, yielded no interesting charts to post) and then ask yourself just how much difference a few million years of evolution makes.  Answer: not nearly as much as we’d like to think.

We've never been very good at being conservative.

And usually, that serves us well in doing the ambitious, hard-hitting journalism that you turn to Mother Jones for. But it also means we can't afford to come up short when it comes to scratching together the funds it takes to keep our team firing on all cylinders, and the truth is, we finished our budgeting cycle on June 30 about $100,000 short of our online goal.

This is no time to come up short. It's time to fight like hell, as our namesake would tell us to do, for a democracy where minority rule cannot impose an extreme agenda, where facts matter, and where accountability has a chance at the polls and in the press. If you value our reporting and you can right now, please help us dig out of the $100,000 hole we're starting our new budgeting cycle in with an always-needed and always-appreciated donation today.
