What did Daniel Kahneman and Tversky discover about decision making?

investors value gains and losses differently

Prospect theory
, a concept developed by researchers Daniel Kahneman and Amos Tversky. Simply stated, Prospect theory says that people are averse to losses more than they value equivalent gains. It was a major breakthrough, and it won the 2002 Nobel prize for economics.
What is heuristic thinking?
A heuristic is
a mental shortcut that allows people to solve problems and make judgments quickly and efficiently

Certainty
.
Isolation effect

Loss aversion

What is an example of prospect theory?

imagine gaining $1,000, then losing that same $1,000
. … That’s part of the premise of prospect theory. We tend to place a greater value on avoiding losses due to the associated negative emotional impact.
How prospect theory affects your decision making?
Prospect theory states that decision-making
depends on choosing among options that may themselves rest on biased judgments
. Thus, it built on earlier work conducted by Kahneman and Tversky on judgmental heuristics and the biases that can accompany assessments of frequency and probability.
Who discovered the anchoring effect?
The anchoring and adjustment heuristic was first theorized by
Amos Tversky and Daniel Kahneman
. In one of their first studies, participants were asked to compute, within 5 seconds, the product of the numbers one through to eight, either as 1 × 2 × 3 × 4 × 5 × 6 × 7 × 8 or reversed as 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1.
What is the belief in the law of small numbers?
The law of small numbers is the
fallacious belief that even small samples should closely resemble the parent distribution from which the sample is drawn

Why is the framing effect important?
Because we want to avoid sure losses, we look for options and information with certain gain. The way something is framed can
influence our certainty that it will bring either gain or loss
. This is why we find it attractive when the positive features of an option are highlighted instead of the negative ones.
