Talk based on “Karla Hoff and Joseph E. Stiglitz, Equilibrium Fictions: A Cognitive Approach
to Societal Rigidity,” American Economic Review, Papers & Proceedings, May 2010.
The dominant developmental model in economics Institutions are the “rules of the game”
Individuals take into account all relevant information and use it well
Generally, ideology has just a “walk-on role”
See Acemoglu-Johnson-Robinson (2005)
Not all economists subscribe to this extreme view … Problems posed by the transition of one
belief system to another “are at the core of the problems of economic development. There is nothing automatic about such a transition being successful.”
North 2005, p. 44 See also Loury 2002
HOW does ideology matter?& WHERE does ideology come from?
Outline of presentation Biases in cognition
Confirmatory bias on perception Pre-confirmatory bias
Views in sociology and anthropology Belief systems shape perception
Our view: Belief systems shape perception but need
themselves to be explained A case study of racial ideology
Elements in a theory of “equilibrium ideology”
Very blurry photo Polly –please insert the most blurry
picture. It should be so blurry that no one could recognize the object in the photo
Medium blur Insert the 2nd most blurry picture.
Again, it should be absolutely impossible to identify the objects in the photo.
Confirmatory bias Classic experiment – Bruner-Potter (1964) Participants were asked to identify blurred
slides The range of blur to which people were
exposed varied across 3 groups Very

Correct identification least likely if the starting slide was very blurred
Why? Initial wrong hypotheses developed at
the “very blurred” stage get in the way of correctly interpreting the data
Economists have shown that if the confirmatory bias is sufficiently severe, or the signals are sufficiently weak, then an individual may come to believe with near certainty that the incorrect hypothesis is true even after an infinite number of signals
Rabin and Schrag 1999
This is interesting here because many of our pre-suppositions come from the society we live in. This has implications for societal rigidity and change.
2nd problem with economists’ view--“Pre-confirmatory” bias
The information that agents collect is structured.
Category systems are collectively held –so there are supra-individual aspects of cognition
These category systems shape perceptions, memory & behavior
I’ll give an economic example later--

A view from sociology & anthropology
Institutions exist at two levels—rules of the game and also symbolic systems
DiMaggio 1991
Institutions shape how we think…. Douglas 1986
Our view The sociologists and anthropologists are
right on the need to incorporate belief systems into our models of development
But still we have no general theory of how ideologies change
Elements in a theory of an equilibrium ideology
Individuals’ beliefs Aggregation of those beliefs Intrinsic values (“unquestioned truths”)
The process is idiosyncratic, so We will focus on an example—race—
& a paradox—the role of beliefs about equality of men in the creation of racial ideology
Political and economic factors + intrinsic values
Categorization and
assignment of meaning• 2 examples
• Race in Virginia• Race in British India
Ex. 1 The construction of race to justify slavery In Virginia, there was initially no
coincidence between skin color and labor status, and no general perception of merit based on color.
In the 17th century, “a substantial number of Virginia’s Negroes were free or became free. And all of them, whether servant, slave, or free, enjoyed most of the same rights and duties as other Virginians. … They could sue and be sued in court. They did penance in the parish church for having illegitimate children.”
--Morgan,1972
Labor unrest in 17th c. Virgina In Bacon’s Rebellion of 1676, Virginia’s
“Poore Endebted Discontented and Armed” turned against the elite in a plundering expedition that spread across the entire state
The fear of unrest contributed to the decline in the reliance on indentured servants and to the abridgement of the liberties of Africans.
“To keep as slaves black men who arrived in that condition was possible and apparently regarded as plain common sense” --Morgan 1972
“It is impossible for us to suppose that these beings should be men; because if we suppose them to be men, one would begin to believe that we ourselves were not Christians”
--Montesquieu
Two fictions emerged • The biological inequality of human
beings with black and white skin. • Only two groups—a continuum was
never recognized
Ex 2 British imperial narrative in India In the 1700’s, the East India Company
“had become a rogue state: waging war …and collecting revenue over Indian territory” that produced massive private fortunes and contributed to famine in Bengal
In the trial of the governor of India, Edmund Burke declared, “I impeach him in the name of the English Constitution, which he has violated and broken,--I impeach him in the name of Indian Millions, whom he has sacrificed to injustice.”
But over the nine years of the trial, the idea that British law applied to agents of Britain in India was salvaged not by finding Hastings guilty (he was acquitted) but instead by inventing a new interpretation of India
What emerged was a “race theory that cast Britons and Indians in a relationship of absolute difference”
Dirks, 2001
Slavery in Antiquity and in Russia
“Right, as the world goes, is only in question between equals in power”
Thucydides 431 BC
There was slavery, but no race theory; &
Slaves often occupied high status positions
Political and economic inequality
+ intrinsic values
Categorization and signification
Entrenchment of invented social
identitiesmanc differences
Entrenchment of invented social identities
Histories were “made up” or suppressed to give content to the “natural” differences between groups
Psychological distancing was impossible because deviations from the etiquette of inter-racial relations could lead to harsh punishment
In Brazil, a former slave could lose his freedom for violations of etiquette
Cultural expressions are regulated –dress, jewelry, parades…
“’Our mothers began telling us about being black from the day we were born.”
--Evers (cited in Ritterhouse 2006)
Caste is an example of an entrenched identity in village North India
No physical markings distinguish castes
With very limited mobility for men in North India, everyone in a village knows the caste of everyone else
Lowest castes were traditionally treated as “Untouchables” & denied opportunities for education or non-menial work

A human bias—forgetting some of one’s failures
Most people remember their successes better than their failures. They “forget” or rationalize some of the failures
E.g. Far more than 50% of automobile drivers,
magistrate judges, married couples, etc. rank themselves as above average
We formalize the idea of race as leading the “reds” to be LESS able than the “greens” to suppress experiences of failure

In a stable equilibrium, the belief generates a level of performance that is consistent with the perception of that performance
The result is that a social construct – race – by influencing perceptions is self-fulfilling

Summary What is race?
--An ideology that arose from oppressive formal institutions that violated beliefs about sovereignty and power that were coming to be taken for granted
Fields, 1982
Why, in general, does ideology matter? It affects perceptions, behavior, and
policies It is not determined only by current
interests-- so it has much more than a “walk-on role”
Political and economic rules
Outcomes “rational expectations”
Distribution of resources
The dominant model in economics
Implications for development policy
The rules of the game are just the tip of the iceberg of a functioning institution. Functioning institutions also have associated with them a story, a belief system— Cognitive sources of resistance to
change
Access to information, changes in the distribution of wealth, & new economic opportunities matter not only directly but because they can
Undermine oppressive myths that are hurtful to individuals &
Change incentives over the “motivated beliefs” that individuals may choose to adopt—
e.g., racial, caste, & other ideologies
