How Scandalous <Emphasis Type="Italic">Is</Emphasis> Knowledge of Evolutionary Psychology?

Biological science is deepening our understanding of life at a brisk rate, but interdisciplinary discourse is not keeping pace. This essay offers an account of themes from evolutionary biology that can enrich appreciation of the complexities of human behavior. Because this topic touches fields with different and more traditional perspectives, frictions and misunderstandings exist, and I have employed examples from a single source in order to clarify the science. In her critique of evolutionary psychology published in her book Scandalous Knowledge, the social theorist Barbara Herrnstein Smith has set forth views that are not in harmony with either evolutionary biology or cognitive neuroscience. She asserts that specialized features of mental processing postulated by evolutionary psychologists are without empirical justification; further, she dismisses the concept as embracing “non-physical mental organs.” There exist, however, numerous examples of how brains process information in specific, functional ways, frequently characteristic of the species. Furthermore, the charge of “non-physical mental organs” is not only wrong; it reveals a failure to recognize that biology has two complementary modes of explanation. One is historical and addresses cause in terms of the historical course of evolution and the process of natural selection. The other is proximate and includes many levels of analysis from molecular to social. Because brains have evolutionary histories, the ‘function’ of a particular aspect of mental processing can have a hypothetical explanation in terms of adaptive advantage that is independent of any knowledge of the underlying neural circuitry. A computational model of the brain and representational processing of sensory information, however, are both compatible with observed properties of neurons in the retina and visual cortex as well as with evolutionary processes. Finally, study of the mental processes of non-human primates provides insight into the evolution of our own minds.

Who gains from contract farming? Dependencies,power relations,and institutional change

ABSTRACT

The paper highlights the mechanisms through which outgrower contract farming creates dependencies at the local level. Using sugarcane case study in Malawi, we show that dependencies are created through redefinition of use rights to customary land and through the redefinition of cash flows into outgrower communities. Through this two-dimensional process, corporations can secure access to land, exert control over local communities and transform the local social relations of reciprocity serving as the pillars of resistance. Our results indicate that contract farming changes rural agrarian relations, transforms local family institutions by carefully selecting a few household members with influence into the scheme and selectively dispossessing the poor community members.     

Promise or pitfall? The limited gains from agricultural trade liberalisation for developing countries

It has become an article of faith in international trade negotiations that farmers in developing countries have much to gain from agricultural trade liberalisation. This paper assesses the evidence for such claims, relying on World Bank data and analyses, United Nations trade data, and other economic modelling carried out to inform the current round of World Trade Organisation negotiations. It concludes that the promise of agricultural trade liberalisation is overstated, while the costs to small-scale farmers in developing countries are often very high.     

Advertising and the Price and Quality of Legal Services: The Case for Legal Clinics

Because the holding in Bates v. State Bar of Arizona is narrow and because some lawyers remain opposed to advertising, the dispute over lawyer advertising continues. Many who favor restricting advertising contend that it will not benefit consumers. They argue that prices must either rise to cover the cost of advertising or, if prices do fall, that quality must also drop.
This article addresses itself to both charges. The first section is theoretical, demonstrating how advertising could lower the costs of producing legal services. Advertising increases the volume of services a lawyer can expect to sell. Greater volume, in turn, allows greater specialization in production, more effective use of systems management, and the substitution of paralegals and capital for lawyer inputs. The authors argue that each of these changes will lower costs, thereby lowering prices without necessarily reducing quality. The second section is empirical, comparing the prices and particularly the quality of services produced by a heavy advertiser, the Legal Clinic of Jacoby & Meyers, and the traditional firms in the Los Angeles market with which the clinic competes. Quality is defined both subjectively and objectively, and original data are presented indicating that the quality of service that the clinic supplies is at least equivalent, and on some measures better, than the quality of service that traditional firms provide.
