Some of you may know the 50/50/90 rule: Anytime you have a 50-50 chance of getting something right, there's a 90% probability you'll get it wrong.
This may remind you of the famous 80/20 rule: in any situation, 20% of the causes produce 80% of the results.
You might not know that a brilliant Italian economist formulated an early precursor of this law, today's great Italian, Vilfredo Pareto.
