Whenever I see one of these polls being published I imagine how I would have answered them when I was that age, and I would have lied about every negative seeming question.
What if the poll wasn’t really anonymous and this data was going to be passed on to future employers or schools?
I’d wager that teenagers these day are much more aware of data collection and more protective of personal information then they were 10-20 years ago. I could be giving them too much credit, though.
