While not involving a decision making process characteristic to heuristics in general, these studies show a reliance on past experience and comparison to the current experience. The similarity heuristic is very easy to observe in the world of business, both from a marketing standpoint and from the position of the consumer. Heuristic Search Techniques — Hill Climbing. For example, the similarity heuristic has been observed indirectly in experiments such as phonological similarity tests. The similarity heuristic directly emphasizes learning from past experience. A heuristic evaluation can basically be defined as a review of your user interface, looking closely at user experience aspects. Decision framing 5.
