Are optimists happier? New study finds too much optimism actually decreases happiness

Unrealistic optimism, pessimism, and realism were compared, with cautious optimism found to have the most positive impact in a study of 1,601 individuals over 18 years.

Are optimists happier? It depends.

A new study by a pair of researchers in the United Kingdom looked at the consequences of these dispositions: unrealistic optimists, unrealistic pessimists, or realists.

It found that being “cautiously optimistic” generates the greatest sense of well-being in the long term.

Past research has found that believing in a bright future does indeed correlate with many positive outcomes.

The basic idea is that optimism makes people better able to handle stressful situations.

But on the other hand, too much optimism can have negative effects.

Like, for example, overestimating the likelihood of positive events, and underestimating the likelihood of negative ones.

In fact, “unrealistic optimism” is extremely common, with many studies suggesting that about 80% of people have a so-called “optimism bias.” But when things don’t work out as planned, that optimism can sour into disappointment.

Pessimism and optimism definition

A handy optimism definition is “the generalized perception that events in one’s life will turn out well.” Pessimism, on the other hand, can be seen as a fear of future events, often accompanied by anxiety, depression, and other stress-related conditions. .

The researchers of the present study used a sample of 1,601 people who took part in the British Household Panel Survey from 1991 to 2009.

This survey consists of a questionnaire covering topics such as a household’s economic activity, health, and finances.

The survey asks, for example, whether respondents expect their financial situation a year from now to be better, worse, or about the same.

Likewise, it asks about their current financial situation, compared to one year ago.

The respondents also answered questions about their general sense of well-being and life satisfaction, via survey tools such as the General Health Questionnaire.

Are optimists happier? Cautiously optimistic vs. unrealistically optimistic

The researchers found that people who misjudge the future, either too optimistically or too pessimistically, have a lower sense of well-being than realists.

The measurement they used was the subjects’ financial expectations versus their actual financial results, over a period of 18 years.

People with the most pessimistic expectations had a 22% reduction in their long-term well-being.

That figure was 14% for the most optimistic people. 

Moreover, the respondents with the most pessimistic expectations experienced a 37% higher level of psychological distress than the realists; for optimists, this figure was 12%.

Why pessimists might experience this distress is perhaps a bit obvious.

They tend to have a negative outlook on things, and when things go badly, that only reconfirms their beliefs.

Unrealistic optimism and distress

But why might optimists experience this distress? The authors propose that a sense of disappointment gradually begins to overpower their optimism.

This, in turn, leads to a drop in their sense of well-being.

More generally, trying to make plans based on inaccurate beliefs (either too positive or too negative) also leads to worse outcomes than correct expectations.

And these suboptimal outcomes have a negative influence on well-being.

Too much optimism can have a price

Interestingly, the study found that the financial optimists are also more likely to smoke.

That’s likely because they underestimate the likelihood of bad things happening, for example smoking-related illness, and thus engage in risky activities.

In general, the paper finds that people who hold false beliefs – whether positive or negative ones – have a lower sense of well-being and life satisfaction than those who are cautiously optimistic.

Being cautiously optimistic generates the greatest sense of well-being

So, are optimists happier? A bit of optimism can indeed have benefits in terms of resilience.

But at a certain point, it seems to become maladaptive.

The benefits of extra optimism then have diminishing returns, and increasing costs.

 “Although unrealistic optimism prevails in the population,” the authors conclude, “it is not a recipe for maximizing well-being.”
