Another way to support this simplification process in product comparisons is to present important information side-by-side rather than only through each individual product page. Replicating patterns of prospect theory for decision under risk, Nature Human Behaviour (2020).DOI: 10.1038/s41562-020-0886-x Although the actual statistical probabilities remained identical, the percentage of people supporting a given plan changed dramatically based on whether or not the outcomes were presented in terms of the number of people who would live versus the number of people who would die. The prospect theory was proposed by psychologists Daniel Kahneman and Amos Tversky in 1979, and later in 2002 Kahneman was awarded the Nobel Prize in economics for it. Loss aversion is a natural human tendency that exists to keep us from incurring losses. The pain of losing also explains why, when gambling, winning $100 and then losing $80 feels like a net loss even though you are actually ahead by $20. First, people treat outcomes that are deemed to be either certain or impossible very differently than those whose changes take place in the midrange of probability. For example, insurance websites frequently display a long list of unlikely, yet costly outcomes that we may encounter should we not buy insurance. This shows that a £100 gain is less than the £100 loss. Loss aversion is the tendency to prefer avoiding losses to acquiring equivalent gains. Yet people largely prefer one option over the other. (The order here is also important — were we to first lose $80, then come back and win $100, it would shift our reference point and make it feel like a net gain!). The second element of the evaluation phase is characterized by the weighting function. Most people will behave so that they minimize losses because losses loom larger than gains, even though the probability of those losses is tiny. People can respond very differently to negatively framed messages than they would to a positively framed one. Because the cat couldn’t provide any family health history, I saw the likelihood of her having an issue as an unknown: there was no way to predict when or if something could pop up and be a major expense. https://www.britannica.com/topic/prospect-theory, University of Zurich - Prospect Theory: An Analysis of Decision Under Risk, Columbia University - Prospect Theory as Efficient Perceptual Distortion, Princeton University - Prospect Theory: An Analysis of Decision Under Risk, The University of Oklahoma - Prospect Theory, Rational Choice and International Relatons, University of California San Diego - Radi School of Management - Prospect Theory. Comparison tables that highlight differences work well, as long as consistent levels of detail are included for all items. The following figure shows the value function of the prospect theory the S-shaped value function depicted in the figure is the central element of the prospect theory. To achieve People tend to overweigh options that are certain, and are risk averse for gains. People tend to be more risk-averse when in a domain of gains, where things are going well and appear to be likely to continue to improve or where actors confront primarily opportunities for gains. The reason for this is that people tend to remember losses more profoundly than gains. Loss Aversion Most people will behave so that they minimize losses because losses loom larger than gains, even though the probability of those losses is tiny. This is because the silver medalist was looking forward to being number one by … We dub this combination 'myopic loss aversion'. Evidence to support this argument are presented in Avineri and Prashker (2003) and Ben-Elia et al. 90% chance to win $1000 or nothing ($0) With option 1, you’re assured to get $900. Remembering all the details of each individual option creates too much of a cognitive load, so it only makes sense to focus on the differentiators. The pain of losing also explains why, when gambling, winning $100 and then losing $80 feels like a net loss even though you are actually ahead by $20. First, the model examines the way in which value is related to the original reference point, or the start of action or choice. So, preferences described by prospect theory or by loss aversion utility allow investors to have different marginal utilities for gains and losses, right? This phase involves two component elements. When we talk about loss aversion, it’s not as simple as looking at how people hate losing. For example, if we have wealth of £100,000 but lose 20% – we will be very unhappy. In both scenarios people were given an initial amount of money, and then had to choose between two alternatives. A person is risk averse if he prefers the certain prospect (x) to any risky prospect with expected value x. 3. One basic tenet of the prospect theory is loss aversion. Seeing every possible final permutation of products or services may cause prospective customers to make a different decision (or just overwhelm them and lead them to abandon the task) than if they were presented one or two products and then given the option to customize them by adding features. Her contributions to SAGE publication's. This coupon (which would only cost you money if they return to purchase more items) would be more appealing and more effective than a sweepstake for $1000 — a reward that is large, but highly unlikely.
