Sports
In Canadian hockey, junior league players are selected based on skill, motor coordination, physical maturity, and other individual merit criteria. However, psychologist Robert Barnsley showed that in any elite group of hockey players, 40% are born between January and March, versus 25% as would be predicted by statistics. The explanation is that in Canada, the eligibility cutoff for age-class hockey is January 1, and the players who are born in the first months of the year are older by 9–12 months, which at the preadolescent age of selection (nine or ten) manifests into an important physical advantage. The selected players are exposed to higher levels of coaching, play more games, and have better teammates. These factors make them actually become the best players, fulfilling the prophecy, while the real selection criterion was age. The same relative age effect has been noticed in Belgian soccer after 1997, when the start of the selection year was changed from August 1 to January 1.
