The 80/20 rule states that about 20% of causes produce about 80% of outcomes.
Accumulative advantage is what begins as a small advantage gets bigger over time. Situations in which small differences in performance lead to outsized rewards are known as Winner-Take-All Effects.
Winner-Take-All Effects in individual competitions can lead to Winner-Take-Most Effects in the larger game of life.
The 1 Percent Rule states that over time the majority of the rewards in a given field will accumulate to the people, teams, and organizations that maintain a 1 percent advantage over the alternatives. You don’t need to be twice as good to get twice the results. You just need to be slightly better.
