In Noise, Daniel Kahneman, Olivier Sibony and Cass R. These are examples of noise: variability in judgments that should be identical. Now imagine that the same doctor and the same judge make different decisions depending on whether it is morning or afternoon, or Monday rather than Wednesday, or they haven’t yet had lunch. Imagine that two doctors in the same city give different diagnoses to identical patients – or that two judges in the same court give different sentences to people who have committed matching crimes. Wherever there is human judgment, there is noise.

It leaves a reader thinking about human nature is full of error, but it can be resolved by consideration.From the world-leaders in strategic thinking and the multi-million copy bestselling authors of Thinking Fast and Slow and Nudge, the next big book to change the way you think. In my opinion, the book provides a different perspective on judgement.

The book is written from a psychological lens but is explained from the necessity of all organisations giving a professional outlook on decisions and judgements. It provides reasoning on the elimination and the need for less noisy judgements. This will help in bringing out the interpersonal judgements and agglomeration. The book is a take on ‘decision hygiene’ by breaking complex judgements into more straightforward assessments. Thus, the book tries to create a balance by creating an argument over its elimination and existence of noise in organisations to make judgements. Eliminating noise can undermine morale and make people think that they are being treated like a machine. Kahneman makes a point that eliminating noise ultimately can be competitive and expensive to do so. By providing insight on solutions, it discusses and challenges applications used for preventing human error or noise. The book investigates the problem of the nose in every sector, for instance, government, business, education and medicine. No book is coherent until given an insight into what can be done? A reasonable questioning with answers. This explains the interpersonal differences arising from personality, different considerations and different use of a similar scale of judgement. This leads to its reader asking if noise is so omnipresent that why it has been noticed before? This is where human psychology takes from. The predictive judgement that ignores the objective sayings blend with noise and limit the quality of judgement. This leads to focusing on the quality of judgement. While discussing the nature of human judgement, it can also point out that judgements can be susceptible in both scenarios.

Yes, both could not be any different but serve the same perspective on noise. Surprisingly, the books involve criminal sentencing (hence the public organisation) and involve insurance (hence the private organisation). It discreetly tells that both private and public organisations can be shockingly noisy. The book has given ample examples of noise decisions offering better understanding for its reader.įrom a readability point, the book is divided into six parts, from bias to noise. However, bias has always occupied the centre of the stage where noise has been hardly recognised. To understand human judgement, both bias and noise need to be studied. The property of noise is the primary purpose of the book. Bias in the sense that they are purposely off-target and noise are those who are expected to agree and end up at different points off target. Authors note that there are two types of judgement- bias and noise. The book overtly mentions human judgements and where they can go wrong. The author does not need an introduction itself his work has contributed to the discipline of psychology and has contributed to human understanding of human nature with flaws and errors.
