The truly false consensus effect: an ineradicable and egocentric bias in social perception.

Consensus bias is the overuse of self-related knowledge in estimating the prevalence of attributes in a population. The bias seems statistically appropriate (Dawes, 1989), but according to the egocentrism hypothesis, it merely mimics normative inductive reasoning. In Experiment 1, Ss made population estimates for agreement with each of 40 personality inventory statements. Even Ss who had been educated about the consensus bias, or had received feedback about actual consensus, or both showed the bias. In Experiment 2, Ss attributed bias to another person, but their own consensus estimates were more affected by their own response to the item than by the other person's response. In Experiment 3, there was bias even in the presence of unanimous information from 20 randomly chosen others. In all 3 experiments, Ss continued to show consensus bias despite the availability of other statistical information.

Illness perception: social cost and coping-strategies of malaria cases.

This paper looks at illness perceptions and lay management of malaria in the context of new settlement. While the new settlement places unique pressures on the population there are several trends observed that have relevance for program planning and implementation.

Relationship of social perceptions and self-concept in bulimia nervosa.

Although numerous studies have examined the families of bulimic individuals, none have explicitly addressed how family factors relate to self-concept among patients with bulimia. This study used L. Benjamin's' structural analysis of social behavior (1974) rating scales to assess how perceptions of parental relationships relate to self-concept. The results indicate that female patients with bulimia perceive both parents as hostilely disengaged. Furthermore, the self-concepts of patients with bulimia were significantly associated with perceptions of paternal attack/friendliness, which differentiated them from control participants. The results are discussed in terms of the possible relations between family factors and self-concept in bulimia.

[Social perception of AIDS risk].

An all-Polish study was carried out of a representative sample of 1402 adult subjects for establishing the level of social knowledge of AIDS, the character of attitudes, the consequences of informative activities etc. The AIDS threat was considered by the responders as low, with subjects with rather more loose sexual life fearing infection relatively less. It may be supposed that this was due to a greater experience with infections, better knowledge and lower threat awareness. The lack of threat awareness of the society seems to be determined in an equal degree by the low knowledge of AIDS and relatively small number of cases in this country. This limited knowledge of AIDS may lead to a more rapid spread of the disease, and, consequently, to panic reactions, intolerance and aggression against patients and risk groups. This could be prevented only by appropriate health education.

The stability of mood and social perception measures in a sample of depressive in-patients.

Forty depressives and 40 matched controls were compared in terms of a number of self-report variables and in terms of their descriptions and evaluations of both real-life and hypothetical social relationships. Clear differences between the two groups reveal poorer self-ratings in the depressive sample, together with a tendency to describe and to evaluate both real and imaginary relationships more negatively. A retest of the depressed patients at the time of discharge from hospital showed improvement only in the two depression measures and not in any of the other self-rating and perceptual measures used. The possibility is discussed that the perceptual variables are predisposing to depression rather than concomitant with it.

Social perceptions of the impacts of Colombo water supply projects.

The complexity of development activities, in which the interactions between various forces often mean that outcomes are unpredictable and unanticipated, highlights the importance of objective and comprehensive evaluations. In the specific case of the evaluation of towns east and south of Colombo water supply projects, the findings have major implications for the implementation of the Millennium Development Goals, if the water-related objectives are to be fulfilled. The study found that 30% of the households of these towns that are receiving clean, piped water are not using it for drinking. Instead, they are continuing to drink contaminated well water. Whereas it is considered that the main beneficiaries of water supply projects have been women and people who are sick, elderly, or disabled, the general perception is that the health conditions of the families have not improved with the provision of clean water (in fact, many claim that their health conditions have deteriorated). In spite of the higher cost of the supplied water, people are willing to pay for it as long as the supply is reliable.

[Social perception of arterial hypertension from a transcultural perspective].

From ethnological and psychological inquiries, during an ordinary elaboration of methodology (between France and West Africa that took place in Ivory Coast) the author emphasizes the differential value of the terms hypertension or hypotension with a systematic claim of a take of blood pressure in Europe. This uncommon fact in West Africa becomes integrated into the notion of a medical technology and raises the problem of evolution of society (non migration, new forms of alimentation, work and urbanization...). While in France the inquiry is dependent on an image of an hypertensive, his body, his personality, his problems; in Ivory Coast people refer to a body language, the psychosomatic damage including the existential malaise politics, cultural confrontations, stress pathology ... all this with periods of high or low tension internal or external pressures, getting out of the medical act consisting in a take of blood pressure or a particular psychic state testing, the nervous break down or anxiety for example. In a methodological field, the author from different levels of view points (sociological, statistical, ethnological and clinical) is in search of an adapted synthetic formula in anthropology for situations of substitution and social differences.

Towards a "virtual pigeon": a new technique for investigating avian social perception.

The purpose of the present study is to examine the applicability of a computer-generated, virtual animal to study animal cognition. Pigeons were trained to discriminate between movies of a real pigeon and a rat. Then, they were tested with movies of the computer-generated (CG) pigeon. Subjects showed generalization to the CG pigeon, however, they also responded to modified versions in which the CG pigeon was showing impossible movement, namely hopping and walking without its head bobbing. Hence, the pigeons did not attend to these particular details of the display. When they were trained to discriminate between the normal and the modified version of the CG pigeon, they were able to learn the discrimination. The results of an additional partial occlusion test suggest that the subjects used head movement as a cue for the usual vs. unusual CG pigeon discrimination.

Environmental risks: scientific concepts and social perception.

Using the example of air pollution, I criticize a restricted utilitarian view of environmental risks. It is likely that damage to health due to environmental pollution in Western countries is relatively modest in quantitative terms (especially when considering cancer and comparing such damage to the effects of some life-style exposures). However, a strictly quantitative approach, which ranks priorities according to the burden of disease attributable to single causes, is questionable because it does not consider such aspects as inequalities in the distribution of risks. Secondly, the ability of epidemiological research to identify some health effects is limited. Third, the environment has symbolic and aesthetic components that overcome a strict evaluation of damage based on the impairment of human health. It is not acceptable that priorities be set just balancing the burden of disease caused by pollution in the environment against economic constraints. As an example of a computation that inherently includes economic analysis, I refer to the proposal of an estimator of mortality in coal mining, i.e., a rate which puts deaths in the numerator and tons of coal extracted in the denominator. According to this estimator, mortality due to accidents decreased from 1.15 to 0.42 in the period 1950-1970 in the United States, for each million tons of coal extracted. However, considering the steep decline in the workforce in the same period, the traditional mortality rate (deaths over persons-time) actually increased. The proposal of a measure of mortality based on the amount of coal extracted is just one example of the attempts to influence decisions by including an economic element (productivity) in risk assessment. This paper has three purposes: One, to describe empirical research concerning the health effects of environmental pollutants; two, to discuss the scientific principles and methods used in the identification of environmental hazards; and three, to critically discuss some of the ethical principles which are applied in medicine and in the assessment and management of risk.
