This is not Wikipedia. If you really believe that average people would not behave this way, say so. If not, asking for a citation is just filibustering.
You are making naked assertions and I'm asking for data, evidence that supports your claims.
It is only appropriate to ask for data for an assertion if you think the assertion has a significant chance of being false.
This thread is for asking any questions that might seem obvious, tangential, silly or what-have-you. Don't be shy, everyone has holes in their knowledge, though the fewer and the smaller we can make them, the better.
Please be respectful of other people's admitting ignorance and don't mock them for it, as they're doing a noble thing.
To any future monthly posters of SQ threads, please remember to add the "stupid_questions" tag.
