Familiar?
An article that supports your view seems sensible. One that challenges it sends you looking for who funded the study.
A decision goes badly, and you find you had doubts about it all along. Your messages from the time say otherwise.
A family argument about medicine stops being about the medicine. Somewhere along the way it became about who knows best.
You feel completely certain, and the certainty itself starts to feel like proof.
A forwarded message confirms what you already suspected, so you pass it on. Checking it can wait.
Someone shows you good evidence against a position you have defended in public, and you hold it more firmly than before.
None of this means you are foolish. The book's argument is that these habits are standard equipment in a social mind, which keeps processing evidence but often with a thumb on the scale. What is ordinary can still be observed, named and examined.
About the book
The book follows self-deception from the private mind out into families, companies, crowds and countries. Each chapter starts with a real event, explains the psychology behind it in plain language, and then turns the idea back on you.
Knowing the name of a bias rarely stops it from working on you. That is why every chapter ends with a reflection exercise that asks you to examine one of your own beliefs, memories or groups, and why the book closes with a toolkit of habits rather than a summary of theories.
“It is standard equipment. It is fitted in every model, including the one reading this sentence.”
What you will explore
Chapter 1
In 1954 a small group in Chicago waited for a flood that never came. What they did next became a founding study of cognitive dissonance, and a way into why money, time and public statements can raise our confidence without adding any evidence.
Chapter 2
Some beliefs mark who we belong to and who we are loyal to. Changing them can feel like betraying family, community or a younger self, which is why arguments about facts so often turn personal.
Chapter 3
For claims we like, we ask “Can I believe this?” For claims we dislike, “Must I believe this?” The chapter traces confirmation bias and motivated scepticism through the morning in 1995 when idols across India appeared to drink milk.
Chapter 4
Memory is rebuilt each time it is recalled, and it tends to be rebuilt in our favour. Hindsight bias, flattering recollections and a confident eyewitness who was wrong show why a note written at the time beats a vivid memory.
Chapter 5
Not reliably. The creator of Sherlock Holmes reasoned carefully in defence of photographs of fairies. A sharper mind can build a more elegant case for what it already wanted to believe.
Chapters 6 and 7
From Mahim Creek to the Monkey Man of Delhi to demonetisation rumours on WhatsApp: how doubt starts to feel like disloyalty in a crowd, how false stories travel, and why corrections work better when they offer a true explanation in place of the false one.
Chapter 8 and the Toolkit
Recording predictions, keeping a log of what you have changed your mind about, and talking to people who disagree without humiliating them. The book treats changing your mind as a skill you can practise.

Leon Festinger and colleagues watched a group of believers reinterpret a failed prediction of catastrophe as a triumph.

Ignaz Semmelweis and the physicians who resisted evidence that their own hands were carrying childbed fever.
New Delhi · 1995
Within hours, people across India reported idols of Ganesha accepting milk. Few ran the test that would have explained it.

Reflection, in practice
Every chapter ends with a reflection exercise. They are short, written tasks: choose a belief, a memory or a group, write a few lines, and compare what you find with what you expected. Here is the structure of the exercise in Chapter 7.
Reflection exercise
A two-page summary of the book’s techniques, organised by the moments you need them. A few of them:

It flags its limits. Each chapter has a box headed “What the research does not say”, covering findings that are disputed, culturally variable or often exaggerated.
It cites its sources. The Notes list the studies, books and news reporting behind every chapter.
It labels its composites. Everyday scenes with named people, such as “Priya” or “Dr Suresh”, are illustrations and are identified as such.
Self-deception: why people, including intelligent and educated people, defend beliefs against the evidence. It covers cognitive dissonance, identity, confirmation bias, memory, motivated reasoning, group belief and misinformation, and ends with practical habits for more honest thinking.
