I'm glad you've raised this point Jason because pretty much all my life I've looked at those statistics for male promiscuity and thought they are not true.

I also heartily agree that the accuracy of answers is highly suspect in a good deal of questionnaires. Partly because we can't help but answer in the image of how we would 'LIKE' to see ourselves.

Which is a completely different slant on what we actually do in practically all human beings.

Good post. Healthy discussion material.


wasnt there some type of formula for this recited in American Pie. I think it was times all girls numbers by three and divide all guys numbers by three

Stupid teen Movies... even helping with market research

Isn't there some neurological evidence also that the part of the brain you use for answering questions and questionnaires is different from that which you use to make the actual decisions? The upshot of this is that even if you answer truthfully, you may well not be telling the truth.


Damn straight brother - claimed data is a waste of time in predicting behaviour - although it does show in some case intentionality and past behaviour.

Partially - people lie.

Partially - somatic markers covertly bias cognition so people think they're thinking one thing, but they ain't.

Great post. Thanks Jason. Let the truth be heard!


Great article and being a science guy I've always wondered how the two averages could logically be different, turns out they can't. Sex and promiscuity are so culturaly ingrained I wonder if any other market research topic could have an error this large?

Reminds me of a survey of an airline that showed it did more take-offs than landings!

This should actually be tought in market research classes. I have feeling it is at least as important as regression and complex models that work great - in theory.
