How to make people like you – and why it is not a trick

Dale Carnegie taught public speaking in New York when, in 1936, he published the book that became one of the best-selling of all time. It is still in print and still read – not because it is refined, but because what it says about people largely holds.

Criticism does not work

The book’s first and perhaps most important claim: criticism makes people defend themselves, not change. The person criticised justifies what they did – and likes you slightly less. Carnegie opens with stories of criminals who insisted to the end that they had acted rightly, and the point is that if they will not take criticism, neither will your colleague.

What criticism does, and what it does not

What you hope happens

Changed behaviour

• The person sees the mistake
• Takes it on board
• Does it differently next time

What actually happens

Defence

• The person justifies what they did
• Looks for reasons you are wrong
• Likes you slightly less

The alternative is not to let everything pass. It is to start with what is genuinely good, to talk about your own mistakes before others’, and to let the other person save face.

Appreciation, not flattery

Carnegie is clear on the difference. Flattery is empty and gets noticed. Appreciation is sincere and specific: something the other person actually did, that you actually value. His claim is that the need to feel important is one of the strongest human drives – and that almost nobody gets enough of it.

Become interested in others

The most quoted line in the book: you will make more friends in two months by becoming interested in other people than in two years of trying to get other people interested in you.

In practice that means remembering names, listening more than you speak, asking about what the other person cares about, and letting them talk about themselves. It sounds simple. Carnegie’s point is that very few people do it.

The argument you cannot win

He is categorical: the only way to get the best of an argument is to avoid it. If you win, the other person has lost face and does not like you. If you lose, you lose. The alternative is to show respect for their view, admit your own mistakes quickly, and ask questions that let the other person reach the answer themselves – so the idea feels like theirs.

The criticism

The most common objection is that the book teaches people to manipulate. Carnegie anticipates it himself and insists none of this works unless it is genuine – a smile you do not mean gets noticed. But the advice can be used cynically, and the book offers few tools for telling the difference.

The examples are from 1930s America, and some are both quaint and uncomfortable. And the book is not research: it is observation and anecdote. Much of what it says has since found support in social psychology, but it is worth knowing it came first, not after.

What holds up

That criticism puts people on the defensive, that people remember how you made them feel, and that genuine interest in others is rarer than it should be – none of that is dated. Read it as a reminder of that, not as a technique.
