The OEM realizes they can produce the same part less expensively and with possibly greater profit, if they do not adhere to all or most of the OE design specifications. The converse happens when the OE factory (e.g., Mercedes-Benz) promotes their brand of a commodity product (e.g., anti-freeze/coolant, spark plugs, etc.) The third heuristic Tversky and Kahneman identify is the representativeness heuristic, although it might be better termed the “similarity” heuristic.

Examples of Availability Heuristic 1. Heuristic Functions in AI: As we have already seen that an informed search make use of heuristic functions in order to reach the goal node in a more prominent way.Therefore, there are several pathways in a search tree to reach the goal node from the current node. For example, quotes that appear in boxes, in a slightly bigger font, with an italic emphasis, are easily recognizable as such. The availability heuristic is the judgmental procedure of reliance on mental sampling, and is demonstrated in the following example. Your feelings of the relative "goodness" or "badness" of a particular person, object, or activity impact the decisions that you ultimately make. It helps to identify many kinds of user experience problems and is conducted against a set of design principles — also known as heuristics (hence the name!).
