Based on research on the increasingly popular unconscious thought effect (UTE), it has been suggested that physicians might make better diagnostic decisions after a period of distraction than after an equivalent amount of time of conscious deliberation. However, published attempts to demonstrate the UTE in medical decision making have yielded inconsistent results. In the present study, we report the results of a meta-analysis of all the available evidence on the UTE in medical decisions made by expert and novice clinicians. The (...) meta-analysis failed to find a significant contribution of unconscious thought to the accuracy of medical decisions. This result cannot be easily attributed to any of the potential moderators of the UTE that have been discussed in the literature. Furthermore, a Bayes Factor analysis shows that most experimental conditions provide positive support for the null hypothesis, suggesting that these null results do not reflect a simple lack of statistical power. We suggest ways in which new studies could usefully provide further evidence on the UTE. Unless future research shows otherwise, the recommendation of using unconscious thought to improve medical decisions lacks empirical support. (shrink)

Proust's madeleine illustrates the automatic nature of associative learning. Although we agree with Mitchell et al. that no compelling scientific proof for this effect has yet been reported in humans, evolutionary constraints suggest that it should not be discarded: There is no reason by which natural selection should favor individuals who lose a fast and automatic survival tool.

Higher plants must undergo a major developmental switch, the transition to flowering, if they are to successfully complete their life cycle. In many plants, the crucial decision of when to begin to produce flowers is primarily controlled by environmental signals. The process of floral induction involves the integration of the activities of two types of genes: those that control flowering time as a response to the environment as well as an endogenous clock, and those that determine the floral identity of (...) the cells. The first direct link between these two classes of genes has now been demonstrated(1). Forced expression of CONSTANS, a flowering‐time gene, promotes flowering through the transcriptional activation of LEAFY, a flower‐meristem‐identity gene. (shrink)

This book provides a detailed reconstruction of the process of formation of the modern concept of society as an objective entity from the 1820s onwards, thus helping to better understand the shaping of the modern world and the nature of the current crisis of modernity. The concept has exerted considerable influence over the last two centuries, during which time many people have conceived themselves and behave as members of a society, and social scientists have explained human subjectivities and conducts as (...) social effects. For both groups, society exists as a very real phenomenon. Historical inquiry shows, however, that the modern concept of society is no more than a historically contingent way of imagining and making sense of the human world.. (shrink)
