A number of people have asked me what I read as background to my Marketing article on ‘predictably irrational’ consumer decision-making. Aside from various interviews I’ve done over the years, here is a list of the main books I’ve read in this arena.
The first two books are game-changers in my view – the two game-changing concepts being ‘choice architectures’ and ‘fair process’. The next five certainly changed the way I thought about these things, and have clear implications for marketing. The rest are in random order.
If there’s something I’ve missed, or if you think my assessment is wrong in some way, please add a comment. It would be great to share notes and create a collective learning exercise.

Nudge (Richard H Thaler and Cass R Sunstein) A seminal piece of work for the way it shifts the focus away from ‘free choice’ – and the assumptions of perfect (i.e. pink elephant) rationality that lie behind it – to ‘choice architectures’: the frameworks, contexts and conditions in which people make their choices. Key message: the most powerful influence on choices is not ‘persuading’ people to make this or that choice, but the ability to tweak their choice architectures: power tends to lie with the choice architect, not with the chooser.
In my view, this book is seminal for marketers. It transforms the agenda when it comes to understanding and influencing decision-making, shifting the debate to another level: to the role of ‘choice architects’ and whether they are using their power responsibly (i.e. to help individuals make better decisions) or manipulatively. Now this genie is out of the bag it cannot be put back. It’s no surprise that one of the authors is now an advisor to the Obama administration. I will return to this seminal debate in future blogs.
Markets and Moral Sentiments (ed Herbert Gintis) Path-breaking series of research essays on the power of reciprocal instincts in decision-making (‘an eye for an eye’/ ‘you scratched my back so I’ll scratch yours’) including their neurochemical underpinnings. My take-out: demonstrates why ‘fair process’ is the next big thing in marketing/business, along with choice architectures.
The Happiness Hypothesis (Jonathan Haidt) Not supposedly about decision-making, but actually one of the best expositions there is. A brilliant book. The first chapter on ‘The Divided Self’ explains more, quicker and better than virtually anything else I have read.
The Things We Do (Gary Cziko) Demolishes behaviourist stimulus-response theories of human decision-making and behaviour and convincingly advocates the equivalent of a Copernican revolution in psychology. The surface appearance – equivalent to believing the sun orbits the earth – is that perceptions (i.e. environmental stimuli) control behaviour. In fact, behaviour is “the control of perception”; organisms are autonomous, goal-seeking entities that behave as they do to control their perceptions (i.e. what they sense). If this is right, the implications for marketing are profound.
Basic Instincts (Pete Lunn) Goes furthest in applying what we’ve learned so far to economics – a valuable contribution.
The Paradox of Choice (Barry Schwartz) Brilliant analysis of the psychological costs of choice.
The Blank Slate (Stephen Pinker) Tour de force demolition of 20th century (and earlier) theories that the human mind is like a piece of wax that’s moulded into shape by impressions received from the environment. (Next step: think through what this means for many common theories about branding, media buying and media measurement).
The Emotional Brain (Joseph Le Doux) Powerful exposition of the power of primeval emotions in decision-making and behaviour.
Descartes' Error (Antonio Damasio) Makes a huge contribution by helping us get past pink elephant theories of ‘rationality’. The key sentences of this book for me are: “certain aspects of the process of emotion and feeling are indispensable to rationality. At their best, feelings point us in the proper direction, take us to an appropriate place in the decision-making space, where we may put the instruments of logic to good use.”
Also useful for its careful exposition of a truly scientific approach. Just one example: “in monkeys whose behaviour is socially well-tuned (as measured by displays of cooperation, grooming and proximity to others) the number of serotonin-2 receptors is extremely high in the ventromedial frontal lobe and the medial temporal cortices in its vicinity, but not elsewhere in the brain; in monkeys exhibiting non-cooperative antagonistic behaviour, the opposite is true.” In other words, there are countless contextual devils in the detail – devils which can turn your previous understanding upside down if you are not careful.
My take-out: when gurus start talking abstractly about things in general – e.g. the effects of serotonin or dopamine on decision-making or behaviour – they are probably talking out of the back of their hats. In this field, my advice would be to start with the assumption that the claimed expert is bullshitting, and then work backwards. (Remember, one well-researched predictable irrationality is our ‘stop there’ tendency; our willingness to believe explanations that ‘seem to make sense’ without really investigating whether they have any real foundation. In marketing, the concept of brand ‘loyalty’ is a classic example.)
Influence: the psychology of persuasion (Robert B Cialdini) One of the earliest books on human decision-making foibles that’s stood the test of time. Good on what happens, less good on why (because at the time it was written, a lot of the research hadn’t been done).
Predictably Irrational (Dan Ariely) Important for its emphasis on the fact that perceptual biases and non-‘rational’ influences on decision-making are not arbitrary. In fact, they are highly predictable and we can understand this predictability – the implication being that we can also find ways of addressing it. This represents another nudge away from a narrow focus on ‘free choice’ to the nature of ‘choice architectures’. In the end however (in my view) the book fails to provide a framework for understanding and becomes a bit of a haphazard list of ‘interesting things’.
The User Illusion (Tor Norretranders) Mind-boggling round-up on brain research that’s still got my head reeling. Two examples: 1) your brain registers what you are going to do a half of second before you ‘decide’ to do it. This seems to suggest that most ‘decision-making’ is not decision-making at all, but merely your consciousness registering that fact that a decision has been made. Can that be true? 2) The conscious brain processes less than 40 bits of information a second; the unconscious brain processes about 11 million bits of information a second. So the unconscious brain outdoes the conscious brain by nearly a million-to-one. Hmm.
Irrationality (Stuart Sutherland) A well-researched round-up of research findings. Full of well-explained, interesting examples. However, lacks a coherent framework and ultimately degenerates into a rather confusing list.
The Brain that Changes Itself (Norman Doidge) Reports on latest research into brain plasticity and its role in learning. Fascinating. The implication is that in many ways we are still living in the dark ages.
The Empathy Gap Focused mainly on US public policy issues, but useful for the way it expands on the ‘choice architect’ idea.
The Mind of the Market (Michael Shermer) A me-too round-up of much of the above, but OK for that.
The Advertised Mind (Erik de Plessis) A curate’s egg. Well explained round-up of lots of brain research marred by unquestioned stimulus-response assumptions and selling a particular advertising measurement methodology.
The Hidden Persuaders (Vance Packard) The first classic exposé of the marketing industry’s attempts to use psychology to ‘manipulate’ consumers. Interesting for what it said about what some marketers/agencies were trying to do in the 1950s and 60s. Trouble is, Packard made the mistake of actually believing their sales pitches.
Similar things are happening today with a gullible press breathlessly and unquestioningly reporting charlatan gurus’ claims that we are close to discovering ‘the buy button’ or the neuroscientific secret of brand preferences. Yuck.
Some books that are not worth reading because they are sensational and/or superficial: Sway (Ori and Rom Brafman) and Buy-ology (Martin Lindstrom).
There are also many books such as Robert Franks’ Luxury Fever that highlight specific types of ‘irrational’ consumer behaviour. The drawback of many of these books is that they focus only on 5% of the picture and talk about it as though it were 100%. They are valuable if you put them into a broader context.
