Effects of Groupthink on Tactical Decision-Making
Irving Janis introduced the theory of groupthink in his classic study Victims of Groupthink in 1972. He attempted to determine why groups, often consisting of individuals with exceptional intellect and talent, made irrational decisions. He concluded that groups often experienced groupthink, a mode of thinking that people engage in when they are deeply involved in a cohesive group, when the memb...
متن کاملGroupthink: Collective Delusions in Organizations and Markets
This paper investigates collective denial and willful blindness in groups, organizations and markets. Agents with anticipatory preferences, linked through an interaction structure, choose how to interpret and recall public signals about future prospects. Wishful thinking (denial of bad news) is shown to be contagious when it is harmful to others, and self-limiting when it is beneficial. Similar...
متن کاملA stochastic model of the emergence of autocatalytic cycles
Autocatalytic cycles are rather common in biological systems and they might have played a major role in the transition from non-living to living systems. Several theoretical models have been proposed to address the experimentalists during the investigation of this issue and most of them describe a phase transition depending upon the level of heterogeneity of the chemical soup. Nevertheless, it ...
متن کاملWithin-Host Stochastic Emergence Dynamics of Immune-Escape Mutants
Predicting the emergence of new pathogenic strains is a key goal of evolutionary epidemiology. However, the majority of existing studies have focussed on emergence at the population level, and not within a host. In particular, the coexistence of pre-existing and mutated strains triggers a heightened immune response due to the larger total pathogen population; this feedback can smother mutated s...
متن کاملEmergence of proto-organisms from bistable stochastic differentiation and adhesion.
The rise of multicellularity in the early evolution of life represents a major challenge for evolutionary biology. Guidance for finding answers has emerged from disparate fields, from phylogenetics to modelling and synthetic biology, but little is known about the potential origins of multicellular aggregates before genetic programmes took full control of developmental processes. Such aggregates...
