In the back side of the book you can read:
Behavioral economics, traffic paradoxes and other metaphors highlight this though-provoking insight into the NBA and your own thinking.
So I bought the book.
Some remarks to remind
Individual scoring is not replaced, it is redistributed.
Look at the global impact of a player, not just to the score.
A tendency to focus on a individual’s scoring while overlooking his other actions that influence the team score.
Individual players are limited in their impact (measured through WOWY (with or without you) method).
Variance, rules of thumb
- Low variance is “consistent”
- High variance is “inconsistent”
- The greater the variance, the larger sampple needed to make accurate conclusions.
Sample size insensitivity
A tendency to consider the given sample as sufficient for reaching a conclusion.
When a team wins, in order to explain why they won, we sift through memories of the positive events in the game. When a team losses, we eximine the negatives. This phenomenom is at the crux of winning bias.
Winning bias: a tendency to overrate how well an individual performed because his team won and underrate how well an individual performed because his team lost.
Winning bias creates a selection filter to find evidence that supports a particular conclusion.
Late game bias
A tendency to incorrectly weigh events as more important the later they occur in the game.
- Good teams win early.
- Clutch play matters little.
- Hero ball and isolation plays are low-efficiency.
- Good teams and good offenses don’t need to rely on a “closer” while bad clutch teams can be great NBA champions.
All of these beliefs about the importance of crunch-time, for both teams and players, come from late-game bias.
The rings fallacy
The false belief that championship rings in team sports are a relevant determiner of an individual’s performance.
The false belief that after a season ends, only the team that won was a “championship” level team.
How well a player’s skill travels to other, retaining value on successful teams. For instance assistants, passings, rim protection…
Lone star illusion
A tendency to cover-credit one player with the majority of a team’s success when there are no other all-stars on the team.
Our mental scoreboards are constructed from heuristics: a way to seek the solution of a problem through non-rigorous methods, such as by trial and error, empirical rules.
Heuristics is basically intuition, guess.
Our heuristics become crutches for our narratives. Over the years we have developed a tendency to focus on individual scoring at the expense of Global Offense or Global Defense contributions.
The book reviews different bias that are present in the way the narratives are done, simplifications are set, etc. To me the explanation of these specific bias and the way the narratives are done is the most valuable learning from the book.
