It's depressing knowing how many people think all polls are scientifically valid representations of the general population. It's well known that even the way a question is stated or worded can influence the outcome of a poll.
This is an encouraging comment, if more people were actually scientific minded enough to realize this type of thing, perhaps we could get out of the ditch we've driven into.
Until I was about 28, myself and my whole group of friends would 95% of the time give bullshit (usually whatever was funniest) answers to anything resembling a poll. Didn't matter how 'private' or anonymous. We thought polls were bullshit, and we treated them thus. Other classmates, even more than us, filled them out as the person they wish they were.
