LU: “I don’t see how you can know how small a problem is, even if you’ve been there 20 years.
Unless you personally know every single person in the place, how would it possible for you to know how many people are not on drugs?”
FF: “Lu it’s very simple to know which guys in a community are on drugs !!!!!!!!!!”
5ish: “I can not believe I am writing this because it seems to be so obvious, but lack of evidence for something (especially your lack of anecdotal evidence) is not proof that something does not exist.”
Thank you 5ish! That was precisely my point. It is possible to know that something exists, but it is much more difficult (and often impossible) to know that it doesn’t exist. In this case, you would have to know every (or nearly every) person in the community in order to know that it’s NOT a problem.
