HEC Paris Associate Professor of Marketing, Kristine de Valck, has been studying the role of social networks in the marketplace since 1999. She explains.
Severe uncertainty, deep uncertainty, radical uncertainty, ambiguity… different actors in a range of fields – decision scientists, risk analysts, climate scientists, central bankers – use a variety of phrases to talk of some extreme, important yet too often ignored form of uncertainty. But what is it? And how should we deal with this particular species of uncertainty: how should we characterise it, communicate it, and decide in the face of it? In this interview, CNRS Research Director and HEC Paris Research Professor Brian Hill explains the concept and unveils applicable tools based on theoretical models for guiding decisions in situations of severe uncertainty.

Mental distortions known as cognitive biases often shifts our judgement away from rational prescriptions. While such biases are normal – it's just the way our brains are wired – they can lead to poor choices, sometimes with disastrous consequences. But new evidence shows how simple training can help us identify these biases and tremendously improve decision-making.
