Realistic optimism

Explain bad events as temporary and specific, expect things can improve, then plan for the obstacles. Positive fantasies alone can backfire.

• Evidence: Some

The idea

When something goes wrong, you explain it to yourself, usually without noticing. Researchers call your usual pattern your “explanatory style”. A pessimistic style explains bad events as caused by things that are lasting, that affect everything, and that are about you [1]. An optimistic style sees the same event as more temporary, more specific, and partly down to circumstances.

The two most useful dimensions to check are how long and how wide:

The optimistic version isn’t a pep talk. Each sentence is more accurate than the pessimistic one, and it points to something you can change.

The second part concerns goals. Simply daydreaming about a good outcome can make you less likely to get it. In four studies, people who held positive fantasies about a job, an exam or a recovery from surgery put in less effort and did worse weeks or months later. People who judged success as likely did better [4]. The difference is between “this would be lovely” and “I think I can make this happen”.

How to use it

Check your explanations. When something goes wrong, write down the sentence in your head. Then ask: Is this always true, or true this time? Does it apply to everything, or to this one area? What else contributed? Rewrite it as the most accurate version, not the most cheerful one.

Use WOOP for goals. This is a short structured version of “mental contrasting”: Wish, Outcome, Obstacle, Plan [6].

1. Wish: something you want that is hard but possible in the next few weeks.
2. Outcome: picture the best result for a minute. How would it feel?
3. Obstacle: now picture the main thing in you that gets in the way. Tiredness, avoiding a conversation, scrolling at night.
4. Plan: write one if-then line: “If [obstacle], then I will [action].”

The order matters. Picturing the good future first and the obstacle second links the two, so the obstacle starts to look like something to deal with rather than a reason to give up [5].

Try the Best Possible Self exercise. Write for a few minutes about your life some years from now, assuming things have gone as well as they reasonably could after hard work. Be concrete: where you live, what you do on a weekday, who’s around. Some studies use a single session; others repeat it over a week.

Common mistakes

• Confusing optimism with denial. “It’ll be fine” with no plan is the positive fantasy that predicts less effort [4]. Name the obstacle.
• Forcing positive spin on everything. Some things really are serious and lasting. Realistic optimism is about accuracy, and about the parts you can still affect. See Focusing on what you control.
• Using WOOP on wishes you don’t believe in. When people expect they can’t succeed, mental contrasting tends to help them let go of a wish rather than chase it [5]. That can be useful, but pick a goal you think is reachable if you want action.
• Only rewriting bad explanations. Do the reverse with good events too. “I prepared well” is more useful than “I got lucky”.

Evidence

Optimism and health. A meta-analysis of 15 studies with almost 230,000 people, followed for nearly 14 years on average, found optimists had a lower risk of heart attack, stroke and similar events (relative risk 0.65) and a lower risk of dying from any cause (0.86) [2]. In the Harvard Study of Adult Development, men whose written explanations at age 25 were more pessimistic had worse physician-rated health from age 45 to 60, even after accounting for their health at 25. That study had only 99 men, all Harvard graduates [1]. These are observational findings: they show optimism goes with better health, not that becoming more optimistic causes it, and the results varied a lot between studies.

Can you build it? A meta-analysis of 29 studies with about 2,900 people found the Best Possible Self exercise raised wellbeing and optimism with small effects compared with control tasks, and positive mood with a moderate one [3]. A meta-analysis of 21 studies of mental contrasting with if-then plans (about 15,900 people) found a small to moderate effect on reaching goals, and the authors noted publication bias means the true effect may be smaller [6].

Rated Some. The health link is consistent but correlational, and the exercises have modest, short-term effects in mostly student samples.
