There was a reference in another thread to the Greater Fool.
For the record, this was referenced improperly ... it was stated that Greater Fools "...took the unconventional road and made it work for them. When everyone looked right, they turned around and looked left. They are realists, dreamers and explorers all rolled into one."
This is not what is generally meant by the Greater Fool Theory.
The Greater Fool Theory states that it is "OK" to make a stupid investment as long as you believe there will be a "greater fool" down the road who will buy it from you at a higher price.
It has nothing to do with innovation, risk taking or thinking outside the box.
