Noise

Más información sobre el libro

From the Nobel Prize-winning author of Thinking, Fast and Slow and coauthor of Nudge comes a groundbreaking exploration of why people make poor judgments and how to improve decision-making. The book illustrates various scenarios where identical situations yield different outcomes, such as doctors providing conflicting diagnoses or judges issuing disparate sentences for the same crime. It highlights how even the same professional can arrive at different conclusions based on seemingly irrelevant factors like time of day or day of the week. This variability, termed "noise," affects numerous fields, including medicine, law, economic forecasting, and performance reviews. Despite its prevalence, individuals and organizations often overlook the impact of noise on their judgments. The authors argue that by recognizing and addressing noise, people can significantly enhance their decision-making processes. With practical solutions to mitigate both noise and bias, the book offers original insights and research-based strategies, similar to those that made its predecessors bestsellers. It delves into why humans are particularly vulnerable to noise in judgment and presents actionable steps to combat it, ultimately aiming to foster better decision-making across various domains.
