When resources collide: Towards a theory of coincidence in information spaces (talk given at #SOCM2015)
1 like961 views
The document presents a theory of coincidences in information spaces and explores how accumulated information propagation can lead to emergent collective action independent of explicit social ties. It examines the concept of informational cascades, focusing on their predictive capabilities and the unintended actions resulting from shared information among human collectives. Additionally, it discusses the importance of analyzing coincidental information occurrences to understand complex interaction patterns across various systems.
