I suggest any social test needs to steps:<br>1. take the biggest most diverse group of people, and test their response <br>to a very specific situation, and filter from the big group a smaller group<br>that has a small error margin in differences their behavior to the test.<br><br>2. run the desired test on the smaller, more synched group.<br><br>So, now you can say:<br>For a group that has this behavior margin in this situation, there is that much chance that the proposed rule takes place.<br><br>Any sentence that doesn't hold to this template is just not trust worthy.
