What is heuristics

If you have negative thoughts, then you might avoid school. For example, if you routinely fix air conditioning units and a customer calls with a common complaint, you make an educated guess as to why the air conditioning unit malfunctioned. The 3 heuristics in psychology are representativeness, anchoring and availability. In the s, psychologists Amos Tversky and Daniel Kahneman studied how people make judgments under uncertainty and from there developed these 3 heuristics known as the judgements under uncertainty heuristics.

An example of anchoring heuristic is doing home improvements. You estimate that it will take you about 2 hours to paint a room. You end up close to that time frame after painting the first room, so you assume the second room, although bigger, will take about the same amount of time — never mind that there are more windows and doorframes to cut around and two sets of curtain rods with brackets.

Representativeness heuristic is when, for example, teachers believe based on a stereotype that children from working class and poor homes will have lower cognitive abilities compared to children from middle class and upper middle-class homes. Instead of keeping an open mind and determining for oneself about the cognitive abilities of each student regardless of their socio-economic level, decisions are made on what similarities a particular group is likely to have so a child from that group is assumed to have those same similarities.

Availability heuristic can happen when you think of a sports drink and only two brands come to mind, so you make a decision based on those two brands. Rather than researching other brands, you take the mental shortcut and decide on one of the two that came to mind.

Heuristics influence our thinking by giving us the easiest and quickest path for us to arrive at a decision. Because of this, our thoughts can then limit how we see the world or reinforce how we see the world. Even animals use heuristics, which can, in turn, limit how they see their world, too. In cognitive psychology, how one thinks determines their behavior. In this way, what type of heuristics and when we use them can have an impact on our behavior.

Two more types of heuristics are familiarity heuristic and fast and frugal heuristic. With regard to familiarity heuristic, this can be seen as gut decisions. You choose the first candidate who comes to mind because there was something familiar and safe about that candidate.

In social psychology, there is the fast and frugal heuristic that is a part of ecological rationality decisions that fit with the information in a given environment. Fast and frugal heuristic is a collection of mental shortcuts an individual can chose from based on factors like information and environment. However, because of bounded rationality limited time, information and cognitive capabilities , our decisions might not be the best ones. Bounded rationality and fast and frugal heuristic are found in behavioral economics.

Another word for heuristic is mental shortcut. Because we make many decisions every day, mental shortcuts take less mental energy and free us up to use that mental energy elsewhere.

Based on what kind of decision we need to make, we automatically choose a heuristic to fit that situation. Because they are a mental shortcut, a way for us to quickly reach decisions without having to do research or put a lot of mental energy into exploring various probabilities and outcomes to every situation, heuristics immediately influence our decision making. This influence can range from good to bad. Some snap decisions save time and money, while others could result in more time and money, for instance.

You develop heuristics based on your past experiences and from information around you. These allow you to make quick decisions with little mental effort. Heuristics, as already mentioned, is a mental shortcut — the easiest and fastest route our mind takes, so we can make a decision.

Cognitive biases, on the other hand, can be the results of those systematic errors in decisions. For example, if a woman wants to work out, she might fear getting big muscles so automatically decides to work out in other ways but not lift weights.

This systematic error in decision making leads to a cognitive bias that women who are physically strong are unattractive. Therefore, women MMA fighters, body builders, boxers and other athletes participating in sports requiring immense strength are all perceived as unattractive. Heuristics are not necessarily bad for judgment and decision making.

They can be of benefit when decisions need to be made that require little cognitive resources, so those resources can be better put to use. Analyzing every decision every day would be time consuming and not much would get done. Here are some examples of real-life heuristics that people use as a way to solve a problem or to learn something:. By reviewing these heuristic examples you can get an overview of the various techniques of problem solving and gain an understanding of how to use them when you need to solve a problem in the future.

The major problem with this method is that if the value of the initial anchor is not the true value, then all subsequent adjustments will be systematically biased toward the anchor and away from the true value. An example of anchoring and adjustment is a salesman begins negotiations with a very high price that is arguably well above the fair value. Because the high price is an anchor, the final price will tend to be higher than if the car salesman had offered a fair or low price to start.
