BELIEF IN A JUST WORLD AND REDISTRIBUTIVE

POLITICS*

ROLAND BE ´ NABOU AND JEAN TIROLE

International surveys reveal wide differences between the views held in

different countries concerning the causes of wealth or poverty and the extent to

which people are responsible for their own fate. At the same time, social ethnographies

and experiments by psychologists demonstrate individuals’ recurrent

struggle with cognitive dissonance as they seek to maintain, and pass on to their

children, a view of the world where effort ultimately pays off and everyone gets

their just desserts. This paper offers a model that helps explain i) why most people

feel such a need to believe in a “just world”; ii) why this need, and therefore the

prevalence of the belief, varies considerably across countries; iii) the implications

of this phenomenon for international differences in political ideology, levels of

redistribution, labor supply, aggregate income, and popular perceptions of the

poor. More generally, the paper develops a theory of collective beliefs and motivated

cognitions, including those concerning “money” (consumption) and happiness,

as well as religion.

INTRODUCTION

International surveys reveal striking differences between the

views held in different countries concerning the causes of wealth

and poverty, the extent to which individuals are responsible for

their own fate, and the long-run rewards to personal effort. American

“exceptionalism,” as manifested by the widely held belief in

the American Dream, is but the most striking example of this

phenomenon. At the same time, ethnographic studies of the working

and middle classes reveal that people do not come to these

views as dispassionate statisticians. On the contrary, they con-

stantly struggle with the cognitive dissonance required to maintain

and pass on to their children the view that hard work and

good deeds will ultimately bring a better life, that crime does not

pay, etc., in spite of signals that life may not always be that fair.

Psychologists have similarly documented the fact that most individuals

feel a strong need to believe that they live in a world that

is just, in the sense that people generally get what they deserve,

and deserve what they get. When confronted with data that

conflicts with this view they try to ignore, reinterpret, distort, or

forget it—for instance, by finding imaginary merits to the recipients

of fortuitous rewards, or assigning blame to innocent

victims.

This paper proposes a theory of why people may feel such a

need to believe in a just world; of why this need, and therefore the

prevalence of the belief, may vary considerably across countries;

and of its implications for redistributive policies and the stigma

borne by the poor.

The basic model works as follows. Because of imperfect willpower,

people continually strive to motivate themselves (or their

children) toward effort, educational investment, perseverance in

the face of adversity and away from the slippery slope of idleness,

welfare dependency, drugs, etc. In such circumstances, maintaining

somewhat rosy beliefs about the fact that everyone
