www.AmericanSecurityToday.com September 2020 - Edition When faced with uncertainty while trying to make a decision, people often rely on a mental shortcut known as the representativeness bias. . While this shortcut can speed up the decision-making process, it can also lead to poor choices and stereo- types. Another challenge for cybersecurity professionals is identifying user characteristics that pose the greatest risk to an organization’s information system. Grouping people together based on specific characteristics or attributes can be both convenient and effective, but it also introduces the risk of representativeness bias (also known as representativeness heuristic). Representativeness bias occurs when we erroneously group people (or other things) together based on qualities that are considered normal or typical for that group. For instance, if you made the statement, “older people are riskier users because they are less technologically savvy than their younger counterparts” you would likely observe affirmative nods from around the room. However, when we take a closer look at the numbers in current research, we find that younger people are actually far more likely to share passwords and they often reuse the same ones across domains. 51
