Economists have long held that the best way to predict human behavior is to assume that people are rational, selfish, and more or
less identical. New research shows that this is not necessarily the case.
The World Development Report 2015 is based on three main ideas: bounds on rationality, which limit individuals’ ability to process
information and lead them to rely on rules of thumb; social interdependence, which leads people to care about other people as well
as the social norms of their communities; and culture, which provides mental models that influence what individuals pay attention
to, perceive, and understand (or misunderstand).
The report has two main goals:
To change the way we think about development problems by integrating knowledge that is now scattered across many
disciplines, including behavioral economics, psychology, sociology, anthropology, neuroscience, and political science.
To help development practitioners use the richer understanding of the human actor that emerges from the behavioral
sciences in program design, implementation, and evaluation.
The central argument of the Reportis that policy design that takes into account psychological and cultural factors will achieve
development goals faster. The main tools — affecting prices through taxes, subsidies, and investments; regulating and legislating;
and providing information — all remain relevant. But once considered from the perspectives of bounded rationality, social norms,
and cultural categories, each tool becomes more complex and more nuanced. Moreover, the standard approach does not include
direct efforts to change social norms or cultural meanings absent the tools of prices, regulation, and information. When people
encounter prices, regulation, and information, their responses are not two-dimensional but often involve a certain psychic depth, a
notion that the standard economic account of human action has long hidden from view. Table 1 lists a series of examples in order
to contrast how nuanced uses of prices, regulation, and information differ from the standard uses, given the same development
objectives (in the table, entries in each row share the same development goal).

PRICES(Prices change the attractiveness of a product along a
two-dimensional demand curve)
Cigarette taxes

temporal, normative, and symbolic dimensions)

REGULATIONS(Regulations and legislation are commands that are

meaning of choices)

Three examples illustrate the kinds of innovative policy initiatives that the WDR will characterize. First, Community-Led Total
Sanitation (CLTS) interventions in India, Indonesia, and elsewhere encourage community members to make public pledges to each
other that they will eliminate open defecation in their community. Harnessing social norms, the CLTS initiatives make a connection
between defecation and promise-keeping or family honor. Once pledges are introduced, pre-existing values surrounding the
importance of promise-keeping are activated. Open defecation comes to be associated with breaking promises to one’s peers, not
convenience. A recent review confirms that CLTS coverage, scale and effectiveness have taken time, but that overall CLTS progress
appears quite consistent despite the very different contexts in the review countries.
Second, some initiatives that give people new experiences have overcome belief traps, in which people hold negative views of a
practice merely because they have never experienced it. For example, if people have never seen women leaders, they are likely to
be biased against them. If they are biased against them, women are unlikely to run and unlikely to get elected. If they do not get
elected, people will not see women leaders. Policy can open the trap. Political affirmative action for women in West Bengal, India,
led some villages to have female leaders. In villages with women leaders, parents’ aspirations for their daughters increased, girls’
education outcomes improved, and there was less bias against women in politics. Even after the political reservations in a village
ended, women ran for and in many cases won elections. The presence of female political representatives produced another
surprising change: it greatly increased the reporting of crimes against women and police responsiveness to such crimes in India.
Other recent research findings suggest the impact of exposure to new experiences and new concepts to increase social capital
(trust), decrease conflict, and improve health.
Finally, poverty is best understood not only as a state of deprivation but as an environment that affects decision making. The kind of
stress that typically accompanies poverty impairs the cognitive development of children and the quality of decision making of adults.
Thus, one way to help people in poverty is to make it simpler for people to make good decisions—to access clean water, enroll their
Thus, one way to help people in poverty is to make it simpler for people to make good decisions—to access clean water, enroll their
children in school, and open a savings account. Lowering the “cognitive taxes” associated with access to basic services is another
policy idea that the WDR will describe and assess.
