Behavioural bias
A CFA term, defined in plain English with the distinction examiners test.
What it means
A systematic departure from rational decision-making, either cognitive — an error of reasoning that education can correct — or emotional, which usually has to be accommodated.
The exam angle
The cognitive/emotional split determines the adviser’s response, and that distinction is what gets tested rather than the list of bias names.
