Mind, Society and
Behavior is the title of World Development Report 2015, recently published by the World Bank. The title of
the report is intended to capture
“the idea that paying attention to how humans think (the
processes of mind) and how history and context shape thinking (the influence of
society) can improve the design and implementation of development policies and
interventions that target human choice and action (behaviour)".
The main point that the report seems to be making is that
policy outcomes depend on psychological and social influences as well as
economic incentives.
The report argues that it is important to take account of
three different kinds of thinking:
- Automatic thinking causes us to simplify problems and base decisions on associations that automatically come to mind. This means that policy outcomes can depend heavily on the framing of choices (the way information is provided) and default options.
- Social thinking causes behaviour to be influenced by social preferences, networks, identities and norms. These influences can lead societies into self-reinforcing patterns of behaviour, which may be highly desirable (e.g. norms of loan repayment) or undesirable (e.g. a culture of corruption).
- Thinking with mental models involves concepts, stories and views of how the world works which influence our understanding of what is possible, what is right and what governments should do. An example cited in the report is that people from disadvantaged groups can have mental models that cause them to under-estimate their own abilities.
The report draws upon a substantial amount of research which
establishes the relevance of these different types of thinking to policy issues.
I am probably more familiar than most readers would be with the underlying research in
psychology, behavioural economic and institutional economics that is referred to in this report. However, it was interesting to see how the authors were able to
draw on an impressive array of relevant research related to poverty, child
development, household finance, productivity, health and climate change.
Anyone with an interest in economic development is likely to
find the overview of the report interesting and easy to read. I read the whole
report, but it took a long time because I kept finding more interesting things
to do. The report seems to have been prepared by bureaucrats to be read by
bureaucrats. As I was reading, I could not help thinking that while psychology and
sociology do influence behaviour, we should not overlook the importance of
pecuniary incentives. I find this kind of report easier to read when I am being
paid.
I found the tone of the report to be slightly irritating,
but I suppose it is difficult not to appear to have superior wisdom when
discussing biases in decision-making of ordinary people. The tone in the rest
of the report is balanced somewhat by a chapter which discusses the biases of
development professionals in the World Bank. The chapter notes, among other
things, that predictions by development professionals grossly understated the
extent to which poor people in selected developing countries perceive
themselves to be in control of their own lives and grossly overstated the
extent to which these people perceive themselves to be helpless in dealing with
life’s problems.
There is a major omission in this report, in my view. Any discussion of the influence of cognitive bias in decision-making on economic development should take into account the influence of bias in the
mental models on economic development policies. There is no
discussion of the deficiencies mental models that led to trade protectionism,
widespread public ownership of business enterprises in many countries or the
over-emphasis on the role of savings and capital investment in economic
development. And there is no discussion of institutional arrangements for policy
development that might help prevent biased views of how the economic growth
process works from continuing to have a huge adverse impact on government
policies in many parts of the world.
This report makes a useful contribution, but it could have been a lot better.
