FYI: The “Paradox of Skill” is the recognition that as the average skill level of a group increases, it actually becomes harder and harder for superstars to occur; as the skill level rises, the variability around the group average declines. This phenomenon helps to explain why despite the improvement in baseball players, no one has hit over .400 since Ted Williams did it 75 years ago, and also provides insight on why it’s getting harder and harder to find “good” active investment managers. Because the whole field has gotten so much better, it’s actually become incredibly difficult to stand out from the (already excellent) pack.

Ted
