Title of research project: Biased decision-making in a naturalistic environment: Implications for forecasts of competitive events.
Decision-makers are often susceptible to judgemental biases, but most research has been laboratory-based. The purpose of this study is to examine whether decision-makers are biased to the same extent in naturalistic environments. Betting markets offer a valuable real-world setting, encompassing many features that are of interest to studies into decision-making: high stakes, uncertain information and time pressure. This study examines three decision making-biases:
-Predecisional bias: adjustment of the evaluation of choice-related attributes to favour the leading option.
-Favourite-longshot bias: under-estimation of high probability outcomes, and over-estimation of low probability outcomes.
-Herding: adjustment of judgements to be more representative of commonly-held beliefs.
The study also involves:
-An investigation of new indicators derived from past prices and whether these can be used to show that decision-makers do not employ all available price-related information, particularly information that involves a higher degree of complexity.
-Development of existing models, to more effectively explore decision-making bias in betting markets.
-An examination of betting exchanges, which are a relatively new type of betting market.
