Replication: No action “Bias” among elite soccer goalkeepers during penalty kicks

Research-assisted source review

What it supports
Goalkeepers dived more often, but their chances of stopping the shot were statistically similar when diving and staying central. More shots were directed left or right, so the authors concluded that frequent diving was not evidence of action bias in this dataset.
Where it may not transfer
The study tests one naturalistic task and outcome, not product decision-making. A null difference does not prove every dive was optimal, and strategy may vary by player, era and available information. It directly challenges generalising from the iconic goalkeeper example.
