Which of the following steps is least likely to be included in the process of developing heuristic-driven bias?
|
|
| C) | Reliance on rules of thumb for investment decisions. |
|
| D) | Developing investment principles through personal experience. |
|
Answer and Explanation
The process of developing heuristic-driven bias starts with developing investment principals through experience, followed by reliance on heuristics (rules of thumb) to make decisions. At this point, imperfect heuristics start to sway investment decisions, and investors make errors. Bad advice can contribute to all of these steps, but it is not a part of the development of heuristic-driven bias.
