EXECUTIVE SUMMARY Bias often operates Risk management practices have changed dramatically over the past few years, with the transformation subconsciously, expected to continue at a much faster pace in the next and has the decade. In recent years, one trend that has contributed to this transformation is debiasing. Bias often operates potential to subconsciously, and has the potential to negatively negatively impact risk decision making. This can have an effect on impact risk the overall risk levels of an organization, and ultimately its bottom-line. decision Training on its own is not an effective long-term solution to mitigate the making. influence of bias on risk decisions. Experts believe analytical tools are more effective in debiasing high frequency risk decisions.1 Risk quality This can have benchmarking tools can be useful in reducing potential biases, which could positively influence how insurer’s select specific risks for underwriting. an effect on Furthermore, benchmarking facilitates strong risk differentiation and potentially benefits operating companies in helping to attract competitive overall risk insurance rates, terms, and conditions. Removing biases through benchmarking, perhaps resulting from individuals’ own personal background levels of an and previous industry experience, also helps operating companies drive rational data-driven investment decisions that are more accurately based organization, on overall performance, industry trends, and risk quality. and ultimately its bottom-line.

A general problem with ANA TICA debiasing is that “the same kinds of biases that distort our thinking Providing decision makers with fact-based in general also distort our thinking inputs about the biases themselves,”10 that is, believing that we ourselves are not prone to bias. This is also known as overconfidence bias. Benchmarking has been identified as a means to mitigate the influence of biases.
