Which behavioural bias causes a person to rely on a “best-fit” process to form the...

The representativeness bias causes individuals to evaluate new information by comparing it to existing stereotypes or patterns that seem to “best fit,” making Option D the correct answer. The Investment Funds in Canada curriculum explains that representativeness occurs when investors “ draw conclusions based on similarities to past experiences without considering probability or statistical relevance .”

This bias leads investors to assume that if something looks like a successful investment from the past, it will behave the same way in the future, even when underlying fundamentals differ. The “best-fit” mental shortcut ignores deeper analysis and often results in incorrect assumptions.

The other options describe different behavioural tendencies. Status quo bias reflects resistance to change. Availability bias focuses on information that is easily recalled rather than most relevant. Hindsight predisposition involves believing past events were predictable after they occur. None of these involve pattern-matching based on perceived similarity.

The CIFC course emphasizes that behavioural biases can negatively affect investment decisions and that advisors must recognize and mitigate them when working with clients. Because representativeness relies on superficial resemblance rather than objective analysis, it is the correct answer.
