"...90 percent of respondents have witnessed poor mobile behavior firsthand... there seems to be a math problem: The survey also found that only 19 percent of respondents admitted to engaging in poor mobile behavior themselves." While your conjecture about people varnishing the truth and not looking realistically at themselves is undoubtedly true, you need to not cite math unless you know what you are doing. You can easily construct lots of models where 19% of a population is causing 90% of an effect, especially over an unspecified time. Think about it. If you still don't understand then, again, don't try to be smart.
