Optimism is an attitude reflecting a belief or hope that the outcome of some specific endeavor, or outcomes in general, will be positive, favorable, and desirable. 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 term derives from the Latin optimum, meaning "best". To be optimistic, in the typical sense of the word, is to expect the best possible outcome from any given situation. This is usually referred to in psychology as dispositional optimism. It reflects a belief that future conditions will work out for the best. As a trait, it fosters resilience in the face of stress. Theories of optimism include dispositional models and models of explanatory style. Methods to measure optimism have been developed within both of these theoretical approaches, such as various forms of the Life Orientation Test for the original dispositional definition of optimism and the Attributional Style Questionnaire designed to test optimism in terms of explanatory style. Variation in optimism between people is somewhat heritable and reflects biological trait systems to some degree. A person's optimism is also influenced by environmental factors, including family environment, and may be learnable. Optimism may also be health. Researchers operationalize the term "optimism" differently depending on their research. As with any trait characteristic, there are several ways to evaluate optimism, such as the Life Orientation Test (LOT), an eight-item scale developed in 1985 by Michael Scheier and Charles Carver. Dispositional optimism and pessimism are typically assessed by asking people whether they expect future outcomes to be beneficial or negative (see below). The LOT returns separate optimism and pessimism scores for each individual. these two scores correlate around r=0.5. Optimistic scores on this scale predict better outcomes in relationships, higher social status, and reduced loss of well-being following adversity.

Optimism

Hope

Hope is an optimistic state of mind that is based on an expectation of positive outcomes with respect to events and circumstances in one's life or the world at large. As a verb, its definitions include: "expect with confidence" and "to cherish a desire with anticipation". Among its opposites are dejection, hopelessness, and despair. Professor of Psychology Barbara Fredrickson argues that hope comes into its own when crisis looms, opening us to new creative possibilities.

Learned helplessness

Learned helplessness is the behavior exhibited by a subject after enduring repeated aversive stimuli beyond their control. It was initially thought to be caused by the subject's acceptance of their powerlessness, by way of their discontinuing attempts to escape or avoid the aversive stimulus, even when such alternatives are unambiguously presented. Upon exhibiting such behavior, the subject was said to have acquired learned helplessness. In humans, learned helplessness is related to the concept of self-efficacy; the individual's belief in their innate ability to achieve goals.
