Collective Irrationality and Positive Feedback
, 2011
"... Recent experiments on ants and slime moulds have assessed the degree to which they make rational decisions when presented with a number of alternative food sources or shelter. Ants and slime moulds are just two examples of a wide range of species and biological processes that use positive feedback m ..."

by applying an optimal feedback strength. Importantly, this optimal value depends on the number of options, so that when we change the number of options the preference of the group changes, producing apparent ‘‘irrationalities’’. We thus reinterpret the idea that collectives show "rational "
A note on Ck(irrationals)
"... The main result in this note was obtained in 2001. It is that Ck(P) does not have a σ-closure-preserving base at the origin consisting of countable unions of the usual basic open sets centered on the origin. A slightly different proof was subsequently published by Gartside and Glyn [1] so this note ..."

will not be published unless it is supplemented by new results. Notation. In our context, X is a space homeomorphic to the space of irrational numbers with the usual topology, while Ck(X) denotes the ring of continuous realvalued functions on X, with the compact-open topology. If h ∈ Ck(X) and K is a compact subset

The Exclusion of the Crowd: The Destiny of a Sociological Figure of the Irrational
- European Journal of Social Theory
, 2006
"... In the late 19th century, a comprehensive semantics of crowds emerged in European social theory, dominated in particular by Gustave Le Bon and Gabriel Tarde. This article extracts two essential, but widely neglected, socio-logical arguments from this semantics. First, the idea that irrationality is ..."

-stone of the European semantics, the notion of suggestion, was severely challenged in the USA. It is argued that this rejection of the suggestion doctrine paved the way for a distinctive American approach to crowds and collective behaviour in which the early European emphasis on irrationality was ignored and crowds
Original Article Emergence of group rationality from irrational
, 2011
"... Evolutionary theory predicts that animal decision makers should be rational, meaning that they consistently choose fitnessmaximizing options. Despite this, violations of rationality have been found repeatedly in humans and other animals. The significance of these violations remains controversial, bu ..."

that groups may evade the irrational consequences of individual limitations by distributing their decision making across many group members. We tested this in the well-studied case of collective nest-site selection by Temnothorax ants. We found that individual ants, but not colonies, strongly violated

The Origins of Collective Overvaluation: Irrational exuberance emerges from simple, honest and rational individual behavior
"... The generation of value bubbles is an inherently psychological and social process, where information sharing and individual decisions can affect representations of value. Bubbles occur in many domains, from the stock market, to the runway, to the laboratories of science. Here we seek to understand h ..."

how communication between decision makers influences the speed and intensity of overvaluation. We show that rational and simple individual level rules combined with honest information sharing are sufficient to generate the collective overvaluation characteristic of irrational exuberance. Further, our
