4. Nobody wants to have sex with the Android wielding sysadmin
What about the iPhone wielding sysadmin? They do exist.
In my experience, that combination works. :)
Woah woah woah. I'm sorry but best, more money correlating to more sex is baseless. I have a hunch that the statistics probably go in the exact opposite direction. Without taking into account birth control, it's well known that birth rates and number of children tend to be much higher for lower income people than higher.
Birth rates have been decoupled from sexual activity since the 1960s at the very least. And are completely irrelevant to that fraction of the sex-having populace that are homosexual.
There is some evidence that higher-status individuals of both genders have more sex; and money is a fairly strong proxy for status in our society.
My guess is that it's one or more of:
1. iPhone users tend to have more money as a group and that correlates with more sex.
2. as a group they tend to be more concerned with appearances and sensual experience and sensation seeking.
3. as a group they are more impulsive.
