For example, when purchasing a new vehicle, people may decide to go with the one they have heard the most about, but this may not be the most logical decision.

The representative heuristic is another example. This heuristic governs the thought process that involves making associations and comparisons to existing models. These comparisons can be useful for some problems, but this can also lead to the type of bias that results in people wrongly establishing cause and effect. For example, representative bias leads to wrongful stereotypes.
