Influence
A social psychologist's book on why people say yes, and how to notice when you're being steered
Why it’s worth your time
Robert Cialdini's Influence names the shortcuts behind a lot of the yeses at work: a favor owed, a colleague who seems to agree, a deadline that suddenly looms. A social psychologist, he groups them into six principles and shows how they get used, sometimes fairly and sometimes not.

How to get it
We don’t earn anything from these links.
- Start with one principle.
Pick the principle closest to a recent yes you regret, or one you'd like to use more honestly, and read how Cialdini says it can be used on you.
- Rewrite one request around the other person's reasons.
Take an ask you need to make this week, of your manager, a peer or another team. Write one line on what it does for them or their goals, one thing you've already done for them or the project, and one honest reason it matters now. Cut anything that only works by pressure, like a deadline that isn't real.

Making it work for you
Every workplace is different. Here’s what to think about before you start, and what might get in the way.
Things to think about
Reciprocation helps explain why the colleague you helped through a launch often makes room for your request later, and why a favor done only to collect can sour once someone notices. Help with no ask attached tends to be the kind that lasts.
What might make this harder
Name the move to yourself, then slow it down: ask for the deadline in writing, or say you'll answer tomorrow. The shortcuts Cialdini describes tend to work fastest when there's no time to think.
Questions people ask
What is Influence by Robert Cialdini about?
A 1984 book by a social psychologist on why people say yes. Cialdini groups the pressures into six principles, reciprocity, commitment and consistency, social proof, authority, liking and scarcity, and explains how they're used and how to resist them. A newer expanded edition adds a seventh, unity.
Is Influence a manipulative book?
It describes techniques that can be used to manipulate, and a good part of it is about recognizing them.
Do the studies in Influence still hold up?
Some better than others, since several well-known social psychology findings looked weaker when retested in the 2010s.
What it says, and how it holds up
You agree to cover a meeting because the person asking covered one for you last month. You sign up for a tool because three other teams already have. Neither choice is foolish; Cialdini's point is that rules of thumb like these spare us from thinking everything through in a crowded day. The trouble starts when someone arranges the cue on purpose. His own site says the textbook version of this work, Influence: Science and Practice, combines experimental evidence with techniques he gathered while working in sales, fundraising and advertising.
The six principles are easy to recognize once named. Reciprocation is the pull to repay. Commitment and consistency is the wish to act in line with what we've already said. Social proof is following people like us when we're unsure, and liking, authority and scarcity do roughly what they sound like. A later expanded edition adds a seventh, unity, and his site now frames the principles as things to use ethically. The same principle can be a fair reason or a trap, depending on whether the cue is true. A real deadline is information; an invented one is a push.
In his review, Eli Bendersky expected something in the spirit of Dale Carnegie and found a book mostly about protecting yourself; he thought it probably a must for salespeople and, for anyone else, an entertaining read on everyday psychology and little more. Social psychology's replication problems have since cast doubt on a number of classic findings, so it's worth holding the percentages loosely and the patterns a little more firmly.
A real negotiation, over a contract or a deal between teams, needs more than an eye for cues. Knowing what you'll do if there's no agreement, and what the other side needs, tends to matter more than how a request is framed. Cialdini's book helps you notice pressure; for working out a fair split, Roger Fisher and William Ury's Getting to Yes, which gave that fallback its best-known name, BATNA, is the obvious next read.
