If 9 out of ten people who attempted to cross the street got hit by a car, would you feel the same way if your friends and aquaintences suggested that you not cross the street.
I think the appropriate analogy is something like:
9/10 people who attempted to cross a busy street without waiting for the crossing light died.
Whereas in trading the reality is:
9/10 people who attempt to cross a busy street after waiting for the appropriate signal, pass safely.
In trading, the market literally shows you its cards. It's like cheating at poker!
