Bias – and iPhone users

Two of the feeds I read reported on the same article yesterday.  I found it amusing that both appeared on the same page, and the second (Flowinga Data) captured my impression of the first (Slashdot) exactly, at least in the headline.

OK Cupid is a huge online dating site with a penchant for data analysis.  In this latest release, they found a correlation between sexual activity and smart phone brand (right).

With this summary from Wired:

“According to OK Cupid’s survey of 552,000 user pictures iPhone users have more sexual partners than BlackBerry or Android owners. By age 30, the average male iPhone user has had about 10 partners while female iPhone users have had 12. By contrast, BlackBerry users hover around 8 partners and Android users have a mere 6.”

“Anonymous Coward” at Slashdot concludes that “Numbers Show iPhone Owners Get More Sex.”

Meanwhile, the folks at Flowing Data points out that this is no more than correlation (never to be confused with causation, as every scientist and statistician should know) and that, just as likely, “iPhone users are more promiscuous.”

The whole thing is just packed with interesting discussion points about worldview, bias, and wishful thinking,

There’s more from OK Cupid – your online date will be 2 inches shorter than he claims, will make 20% less than he states, and that picture is at least two years old, especially if it’s good.

P.S. I don’t have a smart phone.
