Values or Fear of What People Say

One of the famous psychological master puts some bread on the floor and asks a question to audiences at a seminer that
-Would you run over this bread if I give you 100$?
-(Silence)
-500$
-(Silence)
-1000$

• Hey , you can not make us do it even if you give us 5000$
• This is the value training

And Master added, No one does this, but you lie and gossip for free ? Isin't it interesting?
