The costs of optimism and the benefits of pessimism.

Research suggests that optimism feels good. However, does it always feel good? We suggest that the benefits (and costs) of optimism and pessimism depend on their timing. A study of exam score estimates revealed that, after controlling for actual exam performance, optimistic expectations are unrelated to how people feel immediately before feedback, in contrast to the common wisdom that optimism "feels good." Furthermore, optimism has costs after feedback-participants who predicted higher scores…

Assessing the consequences of unrealistic optimism: Challenges and recommendations
Neither an Optimist Nor a Pessimist Be: Mistaken Expectations Lower Well-Being
It is found that, as measured by two established well-being indicators, those with mistaken expectations, whether optimistic or pessimistic, do worse than realists, and plans based on inaccurate beliefs are bound to deliver worse outcomes than would rational expectations.
Optimism - Is the Conceptual Glass Half-Empty (or Half-Full)
Optimism has been a favourite topic of research in positive psychology. Optimism, defined as a generalized positive expectancy for the future, is generally regarded as a positive trait. However,
Taking Stock of Unrealistic Optimism
Drawing from 3 decades of research, critically how researchers define unrealistic optimism is discussed, and four types of unrealistic optimism are identified that reflect different measurement approaches: unrealistic absolute optimism at the individual and group levels and unrealistic comparative optimism atThe individual andgroup levels.
Even Optimists Get the Blues: Interindividual Consistency in the Tendency to Brace for the Worst.
Trait-like differences in future outlooks seem to influence only the level and not trajectories of outcome predictions, pointing to relative commonalities in the development of the tendency to brace for the worst.
The Effects of Expectation Disconfirmation on Appraisal, Affect, and Behavioral Intentions
People's risk perceptions can have powerful effects on their outcomes, yet little is known about how people respond to risk information that disconfirms a prior expectation, suggesting that the provision of objective risk information may improve or diminish the likelihood of behavior change depending on people's initial expectations and their emotional and cognitive reactions to the information.
A Primer on Unrealistic Optimism
Unrealistic optimism can be operationalized in multiple ways; is commonplace yet has well-established boundary conditions; occurs for a variety of reasons; and has consequences for affect, decision making, and behavior.
Causes and Consequences of Expectation Trajectories
Well-informed voters were likely to lower their expectations regarding the measure’s passage as the vote neared, in line with polling results, but being informed about the initiative had less impact on expectation trajectories among voters who favored the measure than among those who opposed it.


Anticipating one's troubles: the costs and benefits of negative expectations.
Expecting one's troubles may be a poor strategy for maximizing positive affect because people felt worse when they were expecting a negative than a positive event; but once the event occurred, their prior expectations had no measurable influence on how they felt.
Prescribed Optimism: Is It Right to Be Wrong About the Future?
If people believe, rightly or wrongly, that unrealistic optimism has some value, then optimistic bias may be usefully understood as being consistent with people's values and beliefs.
Defensive pessimism, optimism, and simulating alternatives: some ups and downs of prefactual and counterfactual thinking.

Four studies investigated the prefactual (alternative preoutcome predictions) and counterfactual (Alternative postoutcome "what might have beens") mental simulations of defensive pessimists and optimists, finding individual differences in strategies of prefactual andcounterfactual thinking.
The Affective Consequences of Expected and Unexpected Outcomes
These two theoretical approaches were tested in three studies and the results consistently support DAT, which predicts that bad outcomes feel worse when unexpected than when expected, yet good outcomes feel better when unexpectedthan when expected.
Forsaking Optimism
Although subjective optimism is generally regarded as adaptive, people show a sharp decline in optimism when they anticipate self-relevant feedback in the near future. The authors discuss moderators
Decision Affect Theory: Emotional Reactions to the Outcomes of Risky Options
How do people feel about the outcomes of risky options? Results from two experiments demonstrate that the emotional reaction to a monetary outcome is not a simple function of the utility of that
Choices, Values, and Frames
We discuss the cognitive and the psy- chophysical determinants of choice in risky and risk- less contexts. The psychophysics of value induce risk aversion in the domain of gains and risk seeking in

Meta-analytic findings indicate that optimists may adjust their coping strategies to meet the demands of the stressors at hand, and that the optimism-coping relationship is strongest in English-speaking samples.
Self-Criticism and Self-Enhancement: Theory, Research, and Clinical Implications
In recent years, we have witnessed a proliferation of writing on "positive psychology" that focuses on variables such as optimism, personal control, self-esteem, and personal striving. At the same
