The subject of enquiry is the variation seen in the results of a specific set of studies about methods for training peoples judgment. This review attempts to synthesise the studies findings, and tests hypotheses about the causes of the variation. Research questions ask if variation is attributable to differences in participant characteristics, different aspects of judgment having been targeted, different tasks having been performed or different training strategies having been used. Relevant literature was reviewed, and studies that reported a method for training an aspect of judgment were selected for further quantitative analysis if at least two groups had been randomly selected from a larger set of human adults, one of which received training that another did not, and where, during the test phase, members of no group had access to tools or resources, performed tasks, or received feedback which members of another group did not. A meta-analysis of statistical data from 39 published studies was conducted. The findings are interpreted as indicating variation in the effect of training is attributable to differences in task type and differences in training strategy. The effect of training is greatest in the studies that have diagnostic tasks (p<0.05). The studies that trained participants with examples have, on average, greater effect sizes than studies that did not (p<0.05). Implications, limitations, and avenues for further research are discussed. It is concluded that the findings indicate that different tasks and different training strategies account for a significant proportion of the variation in training effect seen between the selected studies.
