Are well off people more honest? This is certainly what we should expect as they have less need.
An American entertainer named Johal posed as a blind man with a $500 winning ticket. He then proceeds to ask total strangers to check the ticket for him. Interestingly two well-dressed people both informed him the ticket was worthless, with one even attempting to pocket it. But when he approached two homeless people, both confirmed that the ticket had value.
The result is a shocking reminder that we should not judge a book by its cover, nor believe too much in stereotypes.
