They worked for three days in ______ without feeling tried.
Most people also exhibit "unrealistic optimism", a tendency to predict a uniquely bright and rosy future for themselves. College students asked to predict their own future compared to that of their classmates believed, on average, that they were more likely to graduate higher in their class, get a better job, earn a higher salary, have a happier marriage, and bear a gifted child. They also believed that they were less likely to get fired, become depressed, become involved in a car accident, or suffer from a heart attack. Many other examples illustrate this point—as when voters predict that their favored candidate will prevail and sports fans bet on their favorite teams to win.
Psychologists used to agree that an accurate perception of reality is vital to mental health. More and more, however, this view is being challenged by research on positive illusions. Are these illusions a sign of well-being or symptoms of disorder？
In 1988 two psychologists reviewed the relevant research and noticed that people who are mildly depressed or low in self-esteem have less inflated and sometimes more realistic views of themselves than do others who are better adjusted. Their self-appraisals are more likely to match appraisals of them made by neutral others, they are less likely to exaggerate their control over uncontrollable events, and they make more balanced predictions about the future. Based on these results, psychologists arrived at the provocative conclusion that when it comes to the self, positive illusions—not accurate perceptions of reality—promote health and well-being. In their words, "these illusions help make each individual's world a warmer and more active and beneficent place in which to live." In fact, research involving people under stress—such as people with serious illnesses—shows that perceived control, optimism, and other positive beliefs are "health protective" psychological resources that help people cope with adversity.
Others are not so sure that eternal optimists are better off than hard realists. They argue that positive illusions can give rise to chronic patterns of self-destruction—as when people escape from self-awareness through the use of drugs and deny health-related problems until it s too late for treatment. In studies of interpersonal relations, people with inflated rather than realistic views of themselves were rated less favorably on certain dimensions by their own friends. In these studies, self-enhancing men were seen as assertive and ambitious, which are OK, but also as boastful, condescending, hostile, and inconsiderate. Self-enhancing women were seen as more hostile, more defensive and sensitive to criticism, more likely to overreact to minor setbacks, and less well liked by others. Consistent with these findings, other research shows that people filled with high self-esteem are more likely to lash out angrily in response to criticism, rejection, and other bruises to the ego. The result. People with inflated self-images may make a good first impression on others but they are liked less and less as time wears on.

Be Aware: Teenage Driver
A recent study, published in last week's Journal of American Medical Association, offers a picture of how risky it is to get a lift from a teenage driver. Indeed, a 16-year-old driver with three or more passengers is three times as likely to have a fatal accident as a teenager driving alone, by contrast, the risk of death for drivers between 30 and 59 decreases with each additional passenger.
The author also found that the death rates for teenager drivers increased dramatically after 10 pm, and especially after midnight. With passengers in the car, the driver was even more likely to die in a late-night accident.
Robert Foss, a scientist at the University of North Carolina Highway Stately Research Center, says the higher death rates for teenage drivers have less to do with "really stupid behavior" than with just a lack of driving experience. "The basic issue, " he says, "is that adults who are responsible for issuing licenses fail to recognize how complex and skilled a task driving is. "
Both he and the author of the study believe that the way to mitigate(使……缓解) the problem is to have states institute so-called graduated licensing systems, in which getting a license is a multistage process. A graduated license requires that a teenager first prove himself capable of driving in the presence of an adult, followed by a period of driving with passenger restrictions, before graduating to full driving privileges.
Graduate licensing systems have reduced teenage driver crashes, according to recent studies. About half of the states now have some sort of graduated licensing system in place, but only 10 of those states have restrictions on passengers. California is the strictest, with a novice(新手) driver prohibited from carrying any passenger under 20 (without the presence of an adult over 25 ) for the first six months.
