A common idiom used to illustrate optimism versus pessimism is a glass filled with water to the halfway point : an optimist is said to see the glass as half full, while a pessimist sees the glass as half empty.
The tendency to be over-optimistic, underestimating greatly the probability of undesirable outcomes and overestimating favorable and pleasing outcomes (see also wishful thinking, valence effect, positive outcome bias, and compare pessimism bias). [109] [110] Ostrich effect
The ambiguity effect is a cognitive tendency where decision making is affected by a lack of information, or "ambiguity". [1] The effect implies that people tend to select options for which the probability of a favorable outcome is known, over an option for which the probability of a favorable outcome is unknown.
The ancient Greek philosophers Plato and Aristotle debated economic equality. Painting by Raffaello Sanzio (1509). According to professor of politics Ed Rooksby, the concept of equality of outcome is an important one in disputes between different political positions, since equality has overall been seen as positive and an important concept that is "deeply embedded in the fabric of modern ...
Choice-supportive bias often results in memories that depict the self in an overly favorable light. In general, cognitive biases loosen our grasp on reality because the line between reality and fantasy can become fuzzy if one's brain has failed to remember a particular event. [ 8 ]
According to TRA, attitudes are one of the key determinants of behavioral intention and refer to the way people feel towards a particular behavior. [9] These attitudes are influenced by two factors: the strength of behavioral beliefs regarding the outcomes of the performed behavior (i.e. whether or not the outcome is probable) and the evaluation of the potential outcomes (i.e. whether or not ...
Positive outcome bias may refer to: Publication bias , the tendency for researchers to publish research which had a positive outcome. "Positive" in this sense means "eventful" as opposed to "uneventful"
A simple example is the tossing of a fair (unbiased) coin. Since the coin is fair, the two outcomes ("heads" and "tails") are both equally probable; the probability of "heads" equals the probability of "tails"; and since no other outcomes are possible, the probability of either "heads" or "tails" is 1/2 (which could also be written as 0.5 or 50%).
