I HATE being shocked. I really, really, hate it. Mild shocks that some people find “interesting” or “entertaining” cause me to question their sanity. Even therapeutic use of electricity puts me in a really grumpy mood. Don’t bother to remind me about having two degrees in electrical engineering. I am in control of electricity. It goes where I want it to and it does what I want it to do. It doesn’t flow through any part of my body unless a doctor or therapist prescribes it.

With that background imagine the response I had when reading this report (found via DrX):

It was obvious that the couple was engaged in sexual relations when they died. The deaths apparently were related to the use of an elaborate apparatus utilizing electrical current for stimulation. A heavy metal rod measuring 22 cm in length and 2.5 cm in diameter was inserted 18 cm into the male’s rectum. A small wire was attached by a rubber band leading to a Variac voltage regulator. There was a metal rod 20 cm long with a rounded tip 1 cm wide tapering to 0.75 cm in the shaft. A metal ring was attached to the exposed end and the male partner’s index finger was touching it. The rod was inserted 18 cm into the female’s rectum with a similar wire attached and leading to the voltage regulator. The regulator was set at 90 volts, but the dial could be turned up to 130 volts. In the room nearby were other stimulation devices, including a La Vida vibrator on a bed table and a Niagara type vibrator found under the bed. On the bed table was also noted a 1-lb. jar of lubricating cream. The couple was last seen alive more than 24 hours before. Third-degree burns were found in the rectum and vagina with perforation of the posterior vagina and anterior rectum in the female victim. In the male victim, third-degree burns were noted on the tip of the left index finger, the rectum, and the penis. The voltage regulator was plugged into a wall socket when the police arrived.

I already explained this but apparently some people didn’t get the memo–Sex survey numbers don’t add up, mathematicians say:

But there is just one problem, mathematicians say. It is logically impossible for the mean number of partners for men to be different from the mean for women in any given population with equal numbers of heterosexual men and women, although the mean, or mathematical average, can differ from the median, the middle point of a range. Surveys typically report the median.

Still, mathematicians should set the record straight, said David Gale, an emeritus professor of mathematics at the University of California.

“Surveys and studies to the contrary notwithstanding, the conclusion that men have substantially more sex partners than women is not and cannot be true, for purely logical reasons,” Gale said.

…

Sevgi Aral, who is associate director for science in the division of sexually transmitted disease prevention at the U.S. Centers for Disease Control and Prevention, said there are several possible explanations, and all are probably operating.

One is that men are going outside the population to find partners, to prostitutes, for example, who are not part of the survey, or are having sex when they travel to other countries.

Another, of course, is that men exaggerate the number of partners they have and women underestimate.

Aral said she could not determine what the true number of sex partners is for men and women. “I would say that men have more partners on average,” she said, “but the difference is not as big as it seems in the numbers we are looking at.”

Gale is still troubled. He said invoking women who are outside the survey population cannot begin to explain a difference of 75 percent in the number of partners, as occurred in the study saying men had seven partners and women four. Something like a prostitute effect, he said, “would be negligible.” The most likely explanation, by far, is that the numbers cannot be trusted.

Ronald Graham, a professor of mathematics and computer science at the University of California, San Diego, agreed with Gale. After all, on average, men would have to have three more partners than women, raising the question of where all those extra partners might be.

It’s easy to explain, there is no mystery, other studies have shown the “prostitute effect” is not negligible. Read my previous post for an example that makes it all clear. These guys are professors in California. You shouldn’t expect anything but crap for brains from people like that.
