Sentiment Bias in National Basketball Association Betting
Open accessAbstract
We develop evidence of bettors with sentiment bias in the betting market on National Basketball Association (NBA) games. We use measures of team popularity (arena capacity utilization and team all-star votes received) as proxies for the presence of biased bettors. Analysis of point spreads and bet outcomes for more than 32,000 NBA games played in 1981-2012 shows that bookmakers increase prices on games involving popular home teams, an outcome consistent with sentiment bias. These changes in prices do not translate into higher returns for bettors, suggesting that bookmakers shade point spreads to increase profits.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
