📱 eBook en inglés ARROGANT PREDICTIONS: THE MATHEMATICAL FAILURE OF THE ILLUSION OF VALIDITY

Why do highly paid stockbrokers, political analysts, and corporate strategists continue to make confident predictions about the future, even when their historical track records are mathematically no better than random chance? The answer lies in a devastating cognitive flaw known as the Illusion of Validity.
Discovered by Nobel laureate Daniel Kahneman, this bias occurs when a narrative simply "makes sense." If an expert looks at a set of data and can build a compelling, cohesive story around it, their brain artificially generates a massive spike of absolute confidence in their prediction. The brain completely ignores the fact that the underlying data is highly volatile, incomplete, or statistically useless.
This book deconstructs the psychology of professional arrogance. We examine why corporations spend billions of dollars on forecasting models that are mathematically doomed to fail, and how executives systematically mistake a good, logical story for empirical truth.
Dismantle your reliance on gut feelings. Learn why the most confident person in the boardroom is often the one most blinded by their own narrative logic.
