Olivier Sibony

In The You On AI Encyclopedia

Sibony's 2019 book You're About to Make a Terrible Mistake translated decades of behavioral-economics research into a practical framework for organizational decision hygiene. The book prefigured many of the themes of Noise while focusing on individual strategic errors rather than collective inconsistency.

His role in the Noise collaboration was substantial. Kahneman acknowledged Sibony as the co-author who most consistently pushed the analysis toward implementable interventions, insisting that diagnosis without prescription was inadequate for the practical audiences the book sought to reach.

Sibony has written extensively on AI and decision-making in the post-Kahneman period, including on whether AI tools reduce or amplify the cognitive biases his earlier work documented. His position has been characteristically nuanced: AI eliminates some noise while introducing new failure modes, and the net effect depends on the institutional structures surrounding deployment.

Origin

Sibony completed doctoral work at HEC Paris while maintaining his McKinsey practice, producing research that integrated academic rigor with direct experience of executive decision-making in dozens of large organizations.
