Expert judgment can be seen throughout climate science and even more prominently when discussing tipping points. To provide an accurate characterization of expert we begin by evaluating the existing literature on expertise as it relates to a whole, before then focusing review role in unique context From this turn our attention structured elicitation protocols specifically developed for producin...

The Threshold of Toxicological Concern (TTC) is a pragmatic approach in risk assessment. In the absence of data, it sets up levels of human exposure that are considered to have no appreciable risk to human health. The Cramer decision tree is used extensively to determine these exposure thresholds by categorizing non-carcinogenic chemicals into three different structural classes. Therefore, assi...

Experts are often used to provide uncertainty distributions in risk analyses. They play an importantrole when insufficient data exist for quantification, or when the available data or models are conflicting. Multiplesteps are required in constructing a successful expert judgment process. These steps include selecting andframing the issues, identifying the experts, deciding upon an o...

All too frequently, a software cost estimate is required in the early stages of the life-cycle when requirements and design specifications are immature. To produce a cost estimate under these conditions requires extensive use of expert judgment and addressing significant estimation uncertainty. Research has shown that expert judgment under the right conditions can yield relatively "accurate" es...
