No. It can't . The survey is for beer drinkers. You can't take a sample size this small and try and pull it off as an entire nation, without even showing the statistical analysis. That is why I said demographics are important in all this. For example, what was the average IQ of this sample size of beer drinkers? For all we know they could've sampled 700 idiots who haven't a high school diploma.
Again, I accept the flaws and inconsistencies small survey samples potentially have, but to completely mislead a viewing audience without considering the context of the survey, is unethical. That is the main issue.
