Correlation isn't necessarily causation, folks. Don't become right wing just to find out if you're happier in bed. Hugo Felix

Well, that was unexpected. As reported by Buzzfeed, a YouGov survey asking five European countries about their sex lives found that those on the far-right of the political spectrum were the most satisfied with their bedroom antics. Generally speaking, those on the left and far-left were among the least satisfied.

The survey of more than 19,000 people across the UK, France, Sweden, Germany, and Denmark was conducted for Sex, Lies and the Ballot Box, a new book due out this week. With no exceptions, those describing themselves as “very right wing” were far happier with their frisky frivolities than anyone else on the spectrum.

Those considering themselves to be “centrist” were somewhat happier with their sex lives than those on the “right,” but anyone further left tended to be the least happy. The three unhappiest cohorts were France’s right wingers, with 67 percent of them satisfied, and Britain and Sweden’s “left wing” cohort, who came out worst at just 66 percent satisfied.

By a clear margin, Germany’s far-right were the most satisfied with their naughty times, with 77 percent of them happy. Their very left wingers, on the other hand, were just 71 percent satisfied. In every country bar Germany, people on the right were less satisfied than those smack bang in the center.

This is somewhat bemusing. The left are generally seen as having far more progressive attitudes towards sexual endeavors than their conservative (or indeed hyper-conservative) counterparts, so it comes as a bit of a surprise that the former are less satisfied than the latter.

More importantly, though, this is an excellent example of correlation not necessarily equaling causation. Here’s an example – there have been record lows in terms of executions in the last 20 years. During the same time period, Pokémon emerged and became a phenomenon.

Unsurprisingly, Pikachu and friends are not responsible for the drop in execution rates over recent decades. The two variables do correlate, though, but in this case correlation isn’t indicative of causation.

The same applies here. Being right wing doesn’t automatically mean you will be more thrilled between the sheets, nor does having a happy sex life mean you will suddenly turn to the far-right.

Here's another interesting correlation that means nothing at all. Spurious Correlations
