While heuristics are essential for freeing up your limited cognitive resources , they can also lead to trouble causing us to miss important facts or develop unfair biases. Whether you know it or not, you're likely using a variety of heuristics every day. Psychologists Amos Tversky and Daniel Kahneman are credited with first exploring the science of heuristics in the s, and through their work, they identified several different types of mental shortcuts that most humans use.
Since their initial findings, researchers have continued to explore the field of heuristics and identify new ways we as humans take advantage of an array of mental shortcuts. Here are three of the big ones:. The availability heuristic comes into play any time you make a judgment about something based on your memories of related instances or available information that's specific to that scenario.
If you're pressed for time and have to make a quick decision, the availability heuristic may help you quickly arrive at a conclusion. In other cases, it can lead you astray.
For example, when asked about the probability of plane crashes, homicides and shark attacks, people tend to overestimate the odds of each just because these events are so memorable — that's the availability heuristic at play. The availability heuristic may also be responsible for social media's negative effect on your mood : If all you see in your feed is pictures of people partying in Ibiza, you're likely to assume you're the only one not having the time of your life.
Subsequent works by researchers have introduced a number of other heuristics. There are several theories for the usefulness of heuristics.
The accuracy-effort trade-off theory states that humans and animals use heuristics because processing every piece of information that comes into the brain takes time and effort.
With heuristics, the brain can make faster and more efficient decisions, albeit at the cost of accuracy. Some suggest that this theory works because not every decision is worth spending the time necessary to reach the best possible conclusion, and thus people use mental shortcuts to save time and energy.
Another interpretation of this theory is that the brain simply does not have the capacity to process everything, and so we must use mental shortcuts. Another explanation for the usefulness of heuristics is the ecological rationality theory. This theory states that some heuristics are best used in specific environments, such as uncertainty and redundancy. Thus, heuristics are particularly relevant and useful in specific situations, rather than at all times. Actively scan device characteristics for identification.

Just like psychological heuristics are mental shortcuts, design heuristics are benchmarks for designers to refer back to in order to assure usability.
In this case, the heuristics become a usability checklist. The purpose of design heuristics is to reveal how usability is succeeding or failing on your current projects. However, heuristics are not a catch-all. Testing against users remains the best way to determine usability.

A heuristic is a mental shortcut that allows people to solve problems and make judgments quickly and efficiently. These rule-of-thumb strategies shorten decision-making time and allow people to function without constantly stopping to think about their next course of action.
Heuristics are helpful in many situations, but they can also lead to cognitive biases. Being aware of how heuristics work as well as the potential biases they introduce might help you make better and more accurate decisions. It was during the s that the Nobel-prize winning economist and cognitive psychologist Herbert Simon originally introduced the concept of heuristics when he suggested that while people strive to make rational choices, human judgment is subject to cognitive limitations.
Purely rational decisions would involve weighing all alternatives such as potential costs against possible benefits. But people are limited by the amount of time they have to make a choice as well as the amount of information we have at our disposal.
Other factors such as overall intelligence and accuracy of perceptions also influence the decision-making process. During the s, psychologists Amos Tversky and Daniel Kahneman presented their research on cognitive biases.
They proposed that these biases influence how people think and the judgments people make. As a result of these limitations, we are forced to rely on mental shortcuts to help us make sense of the world. Simon's research demonstrated that humans were limited in their ability to make rational decisions, but it was Tversky and Kahneman's work that introduced the study of heuristics and the specific ways of thinking that people rely on to simplify the decision-making process.
