Do Bigger Contracts Cause Baseball Players to Choke?

Economist Wen-Jhan Jane examined batting in MLB regular-season games from 2015–2018. The study reports evidence of a negative causal effect of audience size on successful batting outcomes in the overall sample, consistent with choking under pressure. Primary study

That finding makes crowd-related performance pressure a legitimate subject for discussion. It does not make every disappointing at-bat a demonstration of it.

Crucially, Jane also reports that star batters tended to excel rather than choke before larger audiences. The study further reports differences between star and nonstar batters in their responses to audience composition. Study abstract and bibliographic record

That counterfinding belongs in the main argument, not in a footnote where it cannot interrupt a good rant. If we invoke this study to explain why scrutiny can hurt performance, we must acknowledge players whose performance moves in the other direction.

Audience size is not contract value. Regular-season batting is not postseason batting. A study's star classification is not automatically a ranking of the largest contracts.

Those distinctions prevent importing the paper's causal claim into a different question. Jane's reported audience effect does not establish that receiving a larger salary makes an athlete more likely to fail in October. Study

Nor should an observed batting outcome be treated as a direct measurement of an individual player's internal anxiety. That would require evidence beyond the result itself.

Our editorial hypothesis is that expectations attached to major contracts might sometimes affect preparation or execution. It remains a hypothesis—not a finding from Jane's study.

Perhaps the pressure discussion is unnecessary. A hitter can fail because the opposing pitcher made a good pitch. A brief run of poor results may not require any psychological explanation. Calling a player a choker can become an unfalsifiable story: a hit proves toughness; an out proves weakness.

That objection is substantial. Still, Jane's research gives us a reason not to dismiss audience-related performance effects altogether. The better response is to narrow the question, preserve the star-batter exception and stop pretending we can identify the mechanism from a television replay. Study abstract

A useful study would follow players across seasons and contract changes, comparing performance with defensible expectations rather than raw disappointment. It would need to address age, health, opponent quality, playing time and selection into postseason appearances.

Researchers would need a defensible pressure measure. Attendance, leverage, media scrutiny and self-reported anxiety describe different things. Combining them under one label would obscure the question. Any proposed mechanism should be specified before the disappointing series, not reverse-engineered afterward.

We would become more persuaded if replicated research found that plausibly independent changes in contract-related expectations produced worse-than-expected postseason execution, with a credible psychological measure connecting the two. Consistent null findings—or improvement under scrutiny—would push us the other way.

Jane's publisher-linked study and RePEc abstract support the limited findings described. The full publisher text was access-restricted; methods and effect sizes were not independently audited. No salary-pressure effect is claimed.
