Abstract:
|
The complexity and subjectivity of the judgement task conceals the existence of
biases that undermines the quality of the process. This paper presents a weighted
aggregation function that attempts to reduce the influence of biased judgements on
the final score. We also discuss a set of desirable properties. The proposed weighted
aggregation function is able to correct the "nationalism bias" found by Emerson et
al. (2009) in the 2000 Olympic Games diving competition and suggest the possibility
of a "reputation bias". Our results can be applied to judgement sports and other
activities that require the aggregation of several personal evaluations.
Keywords: Weighted aggregation function; Judgement by Grading; Nationalism
Bias; Reputation Bias; Bias Correction; Olympic Games.
