Where finding an optimal solution is impossible or impractical, heuristic methods can be used psychological law of consumption pdf speed up the process of finding a satisfactory solution. Heuristics can be mental shortcuts that ease the cognitive load of making a decision.

Heuristics are strategies derived from previous experiences with similar problems. If you are having difficulty understanding a problem, try drawing a picture. If the problem is abstract, try examining a concrete example. From one particular batch of research, Gigerenzer and Wolfgang Gaissmaier found that both individuals and organizations rely on heuristics in an adaptive way. They also found that ignoring part of the information , rather than weighing all the options, can actually lead to more accurate decisions. Heuristics, through greater refinement and research, have begun to be applied to other theories, or be explained by them. CEST breaks down two systems that process information.

At some times, roughly speaking, individuals consider issues rationally, systematically, logically, deliberately, effortfully, and verbally. On other occasions, individuals consider issues intuitively, effortlessly, globally, and emotionally. From this perspective, heuristics are part of a larger experiential processing system that is often adaptive, but vulnerable to error in situations that require logical analysis. In effect, a cognitively difficult problem is dealt with by answering a rather simpler problem, without being aware of this happening. Heuristics can be considered to reduce the complexity of clinical judgements in healthcare. For example, in a study done with children, the children were told to estimate the number of jellybeans in a jar.

Children estimated the number of jellybeans to be closer to the anchor number that they were given. A mental shortcut that occurs when people make judgments about the probability of events by the ease with which examples come to mind. Kahneman experiment, the majority of participants reported that there were more words in the English language that start with the letter K than for which K was the third letter. There are actually twice as many words in the English Language that have K as the third letter as those that start with K, but words that start with K are much easier to recall and bring to mind.

A mental shortcut used when making judgments about the probability of an event under uncertainty. Or, judging a situation based on how similar the prospects are to the prototypes the person holds in his or her mind. For example, in a 1982 Tversky and Kahneman experiment, participants were given a description of a woman named Linda. Based on the description, it was likely that Linda was a feminist. The likelihood of two events cannot be greater than that of either of the two events individually. When asked to make several choices at once, people tend to diversify more than when making the same type of decision sequentially. Describes the phenomenon where people justify increased investment in a decision, based on the cumulative prior investment, despite new evidence suggesting that the cost, starting today, of continuing the decision outweighs the expected benefit.
