The Cognitive Crucible is a forum that presents different perspectives and emerging thought leadership related to the information environment. The opinions expressed by guests are their own, and do not necessarily reflect the views of or endorsement by the Information Professionals Association.

John Boyd is well known to have formally written down very little of his own theories on war and conflict, making researching his concepts challenging and leading many to infer meanings based on their own interpretations—or others'—of what little easily accessible evidence of his thinking remains. In Snowmobiles and Grand Ideals, Ian Brown unpacks Boyd in his own words delivered during his lectures.
