Consensus decision making in human crowds

TL;DR: The authors found that a small informed minority can guide a group of naive individuals to a target without verbal communication or obvious signalling, and that both the time to target and deviation from target were decreased by the presence of informed individuals.
Journal ArticleDOI
Shoal composition determines foraging success in the guppy
TL;DR: This study highlights a possible mechanism by which interindividual variation in behavioral types is maintained in a population of guppies using an overhead fright stimulus and suggests potential foraging benefits to bold individuals through associating with shy individuals.
Journal ArticleDOI
From hawks and doves to self-consistent games of territorial behavior.
TL;DR: A standardized empirical approach to quantify prior‐residence effects is suggested, suggesting a self‐consistent model with feedbacks between individual behavior and population dynamics that produces qualitatively different frequency‐dependent selection on intruders (floaters) than on territory owners.
Journal ArticleDOI
Why do female migratory birds arrive later than males
TL;DR: The results support the mate opportunity hypothesis as an explanation of why protandry is the norm in migratory systems, and show that the effects of sex ratio biases are much stronger than those of EPY production.
Journal ArticleDOI
The role of individuality in collective group movement.
James E. Herbert-Read,Stefan Krause,Lesley J. Morrell,Timothy M. Schaerf,Jens Krause,Ashley J. W. Ward +5 more
TL;DR: If the results found here can be generalized across species and contexts, then although individuality is not entirely lost in groups, social conformity and group-size-dependent effects drive how individuals will adjust their behaviour in groups.
