It is only appropriate to ask for data for an assertion if you think the assertion has a significant chance of being false.
Sure. Your assertion was:
If you offered most people 28 times the market price for their organ, or 28 times the market price for prostituting themselves, they would not take it unless they were starving at the moment.
I think that 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.
