James Surowiecki

Wisdom of Crowds (practitioner-author).

Surowiecki spent nearly two decades as a staff writer at The New Yorker, authoring its 'Financial Page' column. His 2004 book 'The Wisdom of Crowds' argued that aggregating diverse, independent judgements produces more accurate outcomes than expert opinion alone. The work became a foundational text in decision science, behavioural economics, and organisational strategy.
