How truth wins in social groups is an important open problem. Classic experiments on social groups dealing with truth statement issues present mixed findings on the conditions of truth abandonment and reaching a consensus on the truth. No theory has been developed and evaluated that might integrate these findings with a mathematical model of the interpersonal influence system that alters some o...

We are interested in average changes in outcome y after a policy change. As in the case of the medical field, we are interested in the outcomes of a new medicine, including its effectiveness and its side effect. To do that, it is typical that we randomly divide patients into two groups, the treatment group, and the control group. The treatment group is given the medicine while the control group...

Three additions are suggested to the study of interest groups and their role in a democracy. First, different types of interest groups are recognized; in particular, special interest groups, which have a narrow social base, concentrate on limited issues, and benefit mainly their own members, are distinguished from constituencyrepresenting organizations. which have a broad social base, address a...

BACKGROUND Approaches to training biomedical scientists have created a talented research community. However, they have failed to create a professional workforce that includes many racial and ethnic minorities and women in proportion to their representation in the population or in PhD training. This is particularly true at the faculty level. Explanations for the absence of diversity in faculty r...

The psychology of science typically lacks integration between cognitive and social variables. We present a new framework of team innovation in multidisciplinary science and engineering groups that ties factors from both literatures together. We focus on the effects of a particularly challenging social factor, knowledge diversity, which has a history of mixed effects on creativity, most likely b...

Doise (in press) has emphasised that researchers have focused empirical work on only one aspect of the theory of social representations. They have mainly been concerned either with describing the content of existing representations or they have been interested in examining how anchoring and objectification operate. They have left largely unexplored Moscovici’s hypotheses concerning the ways in ...
