One manifestation of the overconfidence effect is the tendency to overestimate one's standing on a dimension of judgment or performance. This subsection of overconfidence focuses on the certainty one feels in their own ability, performance, level of control, or chance of success.
For example, individuals may unconsciously treat an outcome with a probability of 99% as if its probability were 95%, and an outcome with probability of 1% as if it had a probability of 5%. Under- and over-weighting of probabilities is importantly distinct from under- and over-estimating probabilities, a different type of cognitive bias ...
A variant of over-under betting, known as Under Over, [5] is a dice game played at various festivals. The object of the game is to predict whether the dice will roll to a total of under 7, over 7, or at 7. The game is typically played with 2 dice. A player typically places a wager on one of three spaces. These spaces are: Under 7 (usually pays ...
There is a 12% probability (0.12 = 0.15 × 0.80) that the blue cab is (correctly) identified by the witness as blue. There is a 17% probability (0.17 = 0.85 × 0.20) that the green cab is (incorrectly) identified by the witness as blue. There is therefore a 29% probability (0.29 = 0.12 + 0.17) that the cab is identified by the witness as blue.
Most theoretical analyses of risky choices depict each option as a gamble that can yield various outcomes with different probabilities. [2] Widely accepted risk-aversion theories, including Expected Utility Theory (EUT) and Prospect Theory (PT), arrive at risk aversion only indirectly, as a side effect of how outcomes are valued or how probabilities are judged. [3]
Normally a reduction in the probability of winning a reward (e.g., a reduction from 80% to 20% in the chance of winning a reward) creates a psychological effect such as displeasure to individuals, which leads to the perception of loss from the original probability thus favoring a risk-averse decision.
The subjective probability judgments of an event used in the simulation heuristic do not follow the availability heuristic, in that these judgments are not the cause of relevant examples in memory but are instead based on the ease with which situations that did not happen can be mentally simulated or imagined.
One example is which option is more attractive between option A ($1,500 with a probability of 33%, $1,400 with a probability of 66%, and $0 with a probability of 1%) and option B (a guaranteed $920). Prospect theory and loss aversion suggests that most people would choose option B as they prefer the guaranteed $920 since there is a probability ...
