Basketballism

Imagine that tomorrow everyone on the planet forgets the concept of training basketball skills.

The next day everyone is as good at basketball as they were the previous day, but this talent is assumed to be fixed. No one expects their performance to change over time. No one teaches basketball, although many people continue to play the game for fun.

Geneticists explain that some people are born with better hand-eye coordination and are thus able to shoot a basketball accurately. Economists explain that highly-paid NBA players have a stronger incentive to hit shots, which explains their improved performance. Psychologists note that people who take more jump shots each day hit a higher percentage and theorize a principal factor of basketball affinity that influences both desire and skill at basketball. Critical theorists claim that white men’s under-representation in the NBA is due to systemic oppression.

New scientific disciplines emerge and begin studying jump shots more systematically. Evolutionary physiologists point out that our ancestors threw stones more often than they tossed basketballs, which explains our lack of adaptation to that particular motion. Behavioral kinesiologists describe systematic biases in human basketball, such as the tendency to shoot balls with a flatter trajectory and a lower release point than is optimal.

When asked by aspiring basketball players if jump shots can be improved, they all shake their heads sadly and say that it is human nature to miss shots. A Nobel laureate behavioral kinesiologist tells audiences that even after he wrote a book on biases in basketball his shot did not improve much. Someone publishes a study showing that basketball performance improves after a one-hour training session with schoolchildren, but Shott Ballexander writes a critical takedown pointing out that the effect wore off after a month and could simply be random noise. The field switches to studying “nudges”: ways to design systems so that players hit more shots at the same level of skill. They recommend that the NBA adopt larger hoops.
