"...had invited 100,000 web users to take IQ tests..."

Besides the hoax, someone forgot about: "Voluntary response data are worthless." http://news.ycombinator.com/item?id=2772603

Because of that, this should have never even been published.



So are you saying that no response data ever should be published, or people should be forced to take surveys and what not?


Getting good survey data requires that the subjects agree to take a survey before you tell them what will be surveyed. This still biases respondents, obviously, but it puts all surveys on an equal playing field.
