I really don't believe that sending you a dollar indicates whether I am good person or not. I tell you what, if you send me a dollar, I will send you a dollar and then we both can be considered, by your definition, good people. I willing to do it if you are.
Again, I think there are plenty of good people out here but it is up to those individuals where they send their money.
I contribute to several organizations a year who would consider me "good". Again, for your research, you can easily go to any philanthropy website or directly to charities and find out how many donors are out there including companies that donate. That would be the best way to see how generous people are. Your approach, although it may not be, comes across as a scam for you to profit from our generosity in the name of an "experiment".
