Words that begin with “r” are easy to think of; words that have “r” as their third letter are harder to think of, so many people answer this question with “words that begin with ‘r’” when in fact, that’s the wrong answer. See also heuristic. A heuristic is a mental shortcut that helps us make decisions and judgments quickly without having to spend a lot of time researching and analyzing information. Now, what do you think most people would do if presented with a situation in which they could either use the representativeness or base-rate heuristic? flashcard set{{course.flashcardSetCoun > 1 ? You give greater credence to this information and tend to overestimate the probability and likelihood of similar things happening in the future.

It is a shortcut to solving a problem when you’re too lazy or overwhelmed or otherwise unable to solve it the proper way. Straightness heuristic Representative Heuristic Representativeness heuristic – strategy of basing likelihood judgments on. Thankfully, our mind makes things easier for us by using efficient thinking strategies known as heuristics. Read on to discover how our brain draws these conclusions and why they can be wrong.

For every decision, we don't always have the time or resources to compare all the information before we make a choice, so we use heuristics to help us reach decisions quickly and efficiently.

I believe representative was a characteristic of bringing up a memory as an excuse for doing it whereas availability heuristic was saying something along the lines of something that had just happened making that information primary and readily accessible. This is a really scary one! How to avoid it. Judgmental Heuristics o Availability Heuristic Factors that influence availability heuristic: recency, vividness, moo ds o Simulation Heuristic: people determine the likelihood of an event based on how easy it is to picture the event mentally.
