Small differences in performance can lead to very unequal distributions when repeated over time. […] You only need to be slightly better than your competition, but if you are able to maintain a slight edge today and tomorrow and the day after that, then you can repeat the process of winning by just a little bit over and over again. And thanks to Winner-Take-All Effects, each win delivers outsized rewards. We can call this The 1 Percent Rule. 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. […] Thus, the process of accumulative advantage is the hidden engine that drives the 80/20 Rule.
