Expert judgement is routinely required to inform critically important decisions. While expert judgement can be remarkably useful when data are absent, it can be easily influenced by contextual biases which can lead to poor judgements and subsequently poor decisions.

The latter ensures that if judgements are to be used as data, they are subject to the scientific principles of review, critical appraisal, and repeatability. Objectively evaluating the quality of expert data and validating e..
