Thinking Fast and slow, Daniel Kahneman, Penguin Allen Lane, Pg 499.

This review was published in the August issue of The CSR Analyst




Daniel Kahneman, a Nobel Laureate in Economics contributed his groundbreaking work on biases in decision making and uncertainty with Amos Tversky. The process of how the human mind works, the manifestation of heuristics and the application of different types of thinking process have been at the heart of his research. Such an exploration of individual cognition through both the fast intuitive thinking process and the deliberate logical thinking mechanism has had a significant impact in the understanding of unobserved flaws and prejudices of human intelligence. This telling revelation abou flawed intuition and quick interpretation has changed the way in which not just academics but powerful people in seats of decision making view themselves and their failure to realise their own dogmatic assumptions. That human mind is susceptible to systemic errors has made our understanding of our selves by giving us, as Kahneman remarks in the introduction, ‘a richer and more balanced picture, in which skills and heuristics are alternative sources of intuitive judgements and choices.’

The Power of Recognition
The key to understanding flaws in intuition is to primarily decompose intuition itself into a process worth scrutiny. Though expert intuitions seems marvellous to our untrained minds, every human being is capable of making excellent intuitive judgements every day of her life. As Herbert Simon remarked pithily, ‘Intuition is nothing more and nothing less than recognition.’ If intuition and the associated fast thinking process means simply skipping the steps of laborious logical thinking because we identify the pattern, then it is an extremely useful tool in the functioning of human beings. These entirely automatic mental activities through perception and memory serve us well in certain situations but give us a completely wrong picture in others. ‘Our blindness to the obvious and our blindness to our blindness’ is at the core of judgement fallacy.

Kahneman uses the concept of ‘two systems’ to understanding these two variants in thought process- the rapid intuitive understanding and the slow and tedious logical thinking. The ease of the first one and the mental effort required for the latter are dependant not only on the circumstances but also on our state of self at any given point in time. Both internal and external factors influence our choice of thinking and humans in general rely much on intuitions since they find logical thinking ‘mildly unpleasant’ most of the time. The interesting juxtaposition that Kahneman makes is between some internal factors that control our intelligence- people with greater self control usually have a greater ability to use their logical apparatus by taking control of the cognitive task at hand and allocating attention and effort efficiently even as four year old children as an experiment conveys. This association of certain personality traits and intelligence is not new but the experiments and conclusion with respect to heuristics is illuminating.

Overcoming Illusions
The pleasure of cognitive ease and inversely the strain of cognitive effort are instrumental in creating ‘illusions’ of reality in our lives. The machine for jumping into premature conclusion works with a complex system of association, memory and even lack of will and laziness. Understanding the dual self in humans has wide implications in dismantling economists and philosophers in surprising ways. The engaging read divided into five parts slowly unravels the mechanism of our cognition, the biases that favour or hinder it, the impact it has in our choices and decision making and finally the lack of recognition of our own other self. There is never a dull moment while engaging with this book since it prods and provokes us through activity based learning, enriches us through lucid interpretations and direct introduction to an astonishing range of ideas. In a way, this book encompasses the three stages in the author’s intellectual life- that of cognitive bias, alternative process through prospect theory and his recent venturing into the science of ‘happiness’. In the end, it appeals to the sceptic within us to question our easy assumptions and our exaggerated sense of understanding of the world and temper it with a more conscious effortful way of thinking and understanding that might lead us towards a more fruitful assessment of ourselves and the world around. This book is a valuable read that gives immense intellectual satisfaction to those who would like to understand the mechanism of understanding and the cornucopia that the human mind is.
