Regular sex makes you rich. (I give up !)

My list of weird penis and sex stories has just got even longer. The Daily Mail’s story today reports a study conducted by Dr.Nich Drydakis of Anglia Ruskin University that reports an apparent correlation between income and frequency of sexual intercourse. Unusually for such stories, and very usefully for teaching purposes, the original paper is freely available on the internet.

This story could be useful for illustrating a whole range of things :

1) Correlation and causation – Does this mean that if you have more sex your income will increase ?

2) Can self-report be relied on ? – I’ve written before about the perils of self-report studies in relation to penis-size, and this seems to me like another example where it’s entirely possible that people who exaggerate about sexual activity might also exaggerate about their income

3) Generalisation – The Mail’s report of this study reports that it used 7500 participants. At face value this seems this it might add to the generalisability of the studies findings. However, I’m interested to see what my students make of all the participants being Greek. Can we draw conclusions about the UK from such a sample ?. It seems to me that even if the data is reliable, the vast cultural differences might bias the conclusions

All in all this looks like a really useful example that I look forward to trying out with the students
