Evonomics (the next evolution in economics) is a new site trying valiantly to infuse economics debates with relevance, sense and sensibility. Here they retrieved a paper that I published, together with Shaun Hargreaves-Heap, in The Economic Journal. Below you will find my summary of findings from a fascinating and intriguing laboratory experiment that has many implications for the distribution of social power and the beliefs that support it. For the Evonomics site click here or...
The 'haves' of the world are always convinced that they deserve their wealth. That their gargantuan income reflects their ingenuity, 'human capital', the risks they (or their parents) took, their work ethic, their acumen, their application, their good luck even. The economists (especially members of the so-called Chicago School. e.g. Gary Becker) aid and abet the self-serving beliefs of the powerful by arguing that arbitrary discrimination in the distribution of wealth and social roles cannot survive for long the pressures of competition (i.e. that, sooner or later, people will be rewarded in proportion to their contribution to society).
Most of the rest of us suspect that this is plainly false. That the distribution of power and wealth can be, and usually is, highly arbitrary and independent of 'marginal productivity', 'risk taking' or, indeed, any personal characteristic of those who rise to the top.
In this post I present a body of experimental work that argues the latter point: Arbitrary distributions of roles and wealth are not only sustainable in competitive environments but, indeed, they are unavoidable until and unless there are political interventions to keep them in check.
The laboratory experiment central to this post took place some time ago and involved 640 volunteers. It revealed that rigid hierarchies might emerge even among people who are, to all intents and purposes, identical. Of course, discrimination cannot emerge unless there is at least some distinguishing feature (e.g. some are 'left-hookers' or have green eyes, some are men while others are women).
So, to test the hypothesis that systematic discrimination can emerge when subjects seem identical to each other, the experimental design made it impossible for one participant to discern anything other than a wholly arbitrary feature of the 'other'; a feature that is commonly known to be uncorrelated to the character, application, intelligence, motivation or ability of the person involved. What feature? We simply assigned, at random, the colour Blue to half our subjects and the colour Red to the other half.
Could such an arbitrary colour assignment seed stable conventions that discriminated terribly between the Reds and the Blues; i.e. people that were, otherwise, indistinguishable (and who knew that the colour assignments were random and, therefore, meaningless)?
The answer is, contrary to anything economic theory can explain, a resounding 'yes'. (Click here for the academic paper, published in The Economic Journal, reporting on this experiment and here for a longer chapter on the same topic, published recently in this book.)
What does this all mean? What lesson can we learn, from these laboratory experiments, about our societies? Are there insights here that can be of help to political activists and civil rights organisations struggling against systematic discrimination? Below, I (YV) offer a brief summary of the empirical findings and answer questions posed by Nick Hadjigeorge (NH) concerning the political significance of these issues for civil rights activists.
INSIGHTS FROM THE LAB - in six points
NH: Your analysis began with empirical observations of discrimination amongst populations of birds, before you proceeded to human behaviour in the laboratory. Do you have more to say about the institutionalization process that we observe in human societies?
YV: Humans have a capacity that animals lack: the capacity to rationalise ex post and to develop moral (or normative) beliefs. Whereas in bird populations discrimination is based just on a Darwinian replicator mechanism (which ensures that conflict is minimized through the division of birds between those which are programmed to act as hawks and to those that behave dovishly), human societies are at least one order to magnitude more complex. As in the 'Animal republic' so too in human societies the socio-economic games we play (also known as... patriarchal, racially-charged capitalism) are quite primitive and conflictual, giving rise to social divisions between advantaged and disadvantaged groups. The difference is that humans question the conventions around them. They need reasons for accepting them. So, they devise them surreptitiously, covertly, subconsciously. They convert the observation "this is what I am getting" to the belief "this is what I am entitled to". When predictive beliefs acquire a veneer of ethicality, they become solidified and the social order is stabilised. But, at the same time, an opposite force is at work; a subversive one that is akin to mutations in biology. These mutations are acts of rebellion (e.g. a Spartacus or a Malcolm X) that destabilize the social order and the dominant ideology. It is through this tussle between the adaptive, conservative, replicator dynamic and the subversive rebelliousness of political mutations that human history evolves. The institutions of slavery, patriarchy, racism, capitalism etc. all came about in this manner. And were all subverted in that manner too.
NH: Is it your impression that your experimental subjects behaved according to socialization, or is it the result of innate brain-wiring, as in the bird example?
YV: The only innate, hard-wired, aspect of this 'socialization' process has to do with our need, as humans, to rationalize; to have reasons for accepting the conventions regulating our behavior. What David Hume describes in hisTreatise of Human Nature as the surreptitious conversion of an 'is' to an 'ought'. It is this 'thirst for reasons' that is the source of the ideology that solidifies behavioural patterns of discrimination and cooperation but also of the ideology of rebellion, subversion and resistance.
NH: Advantaged members feel entitled to their winnings. What sense do the disadvantaged members feel? Is it injustice, etc?
YV: Yes and no. The disadvantaged experience a mix of emotions. Partly a sense of injustice, partly a sense of pride for not being exploiters, partly an indignation against the advantaged but also partly moral condemnation of other disadvantaged people who are 'uppity', who think they deserve better and who seek to subvert the advantage of the advantaged. After all, the greatest opponents of feminists have been women (who proclaimed that women should stay in the home) and the police forces that attacked anti-Apartheid protesters in the South Africa were mostly black...
NH: What is your opinion on the Civil Rights Movement? Did its members successfully utilise their power as members of the disadvantaged group?
YV: Yes. Broadly speaking, the second great difference between human societies and stratified bird populations (besides our capacity to rationalise and to develop normative beliefs) is the fact that humans, possibly courtesy of Logos (speech, language and reason), tend to correlate our mutations. If you think of mutations as individual acts of resistance against established discriminatory conventions, politics is what happens when these individuals attempt to correlate their mutations, thus giving them a great deal more power to overturn the current conventions. In the 1960s the Civil Rights Movement accomplished this with great success, especially so in view of having recruited into the coalition of subversives members of the advantaged group (e.g. whites who rode on the buses with blacks). If the Movement failed in something it was in that it had no answer to the massive loss of blue collar jobs after 1973, a loss that undermined the vast majority of disadvantaged Americans. But this is another story...
NH: Looking ahead, how do you feel about current movements of disadvantaged members exercising their collective power?
YV: It is the historic duty of victims of arbitrary discrimination to contest it tooth and nail. It is also inevitable that they will keep trying, despite the Sirens that strive to keep them on their sofas, glued to the idiot box, or to immerse them in a cloud of mindless, cheap, plastic consumerism against the background of economic insecurity. The bad news is that, since the 1970s, the economic bedrock on which the civil rights' movement stood has become increasingly brittle. The Crisis of 2008 gave out some hope that the dispossessed would take heart and, through the Occupy Movement, reclaim part of the moral high ground in this never ending struggle. The jury is still out on this. But there is good news: As long as mindless, irrational and multiple patterns of discrimination survive, the human spirit will always produce serious challenges to it and, in so doing, will keep the flame alive.
NH: Does your game theory model/research provide any insight into how these groups should behave?
YV: No. It simply empowers them:
How resistance and Civil Rights groups will organize against discriminatory patterns, and how they will subvert the latter's ideological 'cover', is for them to work out and for us to support.
