As a social experiment, French YouTube user NorniTUBE wanted to see how appearances make a difference in people's willingness to help another. On two parallel occasions, a young man pretends to start coughing and collapse on the street. He cries to passersby for help.
The difference is that one time he's dressed like a homeless man and the other he's in a suit. What happens next is an eye-opener, making us question how we'd react.
