Influence: The Psychology of Persuasion

Robert B. Cialdini · Psychology

Influence is Robert Cialdini's account of why people say yes, and how that agreement is manufactured.

Cialdini's six principles of persuasion are the psychology underneath Voss's tactics, the reason mirroring and labeling actually move people.

02

Getting to Yes: Negotiating Agreement Without Giving In

Roger Fisher and William Ury · Business

Getting to Yes emerged from the Harvard Negotiation Project in the late 1970s and laid out a method its authors called principled negotiation.

The principled-negotiation classic Voss defines himself against; reading both sides of the argument is the fastest way to sharpen your own approach.

03

Difficult Conversations

Douglas Stone, Bruce Patton, and Sheila Heen · Business

Difficult Conversations is the product of the Harvard Negotiation Project, the same research group that produced Getting to Yes.

The Harvard Negotiation Project on the emotional mechanics of hard talks, tactical empathy from the academic tradition Voss both borrows from and rejects.

04

Negotiating the Impossible

Deepak Malhotra · Business

Deepak Malhotra is a professor at Harvard Business School who has spent decades studying how people resolve conflicts that appear completely intractable.

Malhotra shows how to break deadlocks with no money, muscle, or leverage, using framing and process, a natural next move after Voss's playbook.

05

Crucial Conversations: Tools for Talking When Stakes Are High

Kerry Patterson, Joseph Grenny, Ron McMillan, and Al Switzler · Self-help

Crucial Conversations is a book about what to do when the stakes are high, emotions run strong, and opinions diverge.

A scriptable system for talking when stakes are high and emotions run hot, the everyday, boardroom version of Voss's hostage-line pressure.

06

Pre-Suasion: A Revolutionary Way to Influence and Persuade

Robert B. Cialdini · Psychology

Robert Cialdini spent decades studying the principles of persuasion that animate Influence, his 1984 masterwork.

Cialdini's follow-up argues the moment before you make your case decides it, the attention-setting that quietly precedes Voss's calibrated questions.

07

How to Win Friends and Influence People

Dale Carnegie · Self-help

How to Win Friends and Influence People is Dale Carnegie's 1936 guide to dealing with people effectively.

Carnegie's century-old advice to make the other person feel genuinely heard is the plain ancestor of Voss's tactical empathy.

08

To Sell Is Human

Daniel H. Pink · Business

To Sell Is Human is Daniel Pink's case that selling — in the broad sense of moving people to think or act differently — is central to what most of us do at work every day, whether or not our job title includes the word "sales." Drawing on Bureau of Labor Statistics data, Pink estimates that Americans spend roughly 40% of their work time in non-sales selling: persuading, convincing, and nudging.

Pink reframes persuasion as attunement and listening rather than pressure, the same insight that skilled negotiators are first of all skilled listeners.

09

You Can Negotiate Anything

Herb Cohen · Business

You Can Negotiate Anything is Herb Cohen's argument that negotiation is not a special skill reserved for diplomats and dealmakers but a basic life competence exercised continuously — in salary conversations, purchases, relationships, and workplace conflicts.

Herb Cohen's warm, practical classic treats everyday life as a series of negotiations, a friendlier companion to Voss's FBI intensity.

10

Thinking, Fast and Slow

Daniel Kahneman · Psychology

Thinking, Fast and Slow is Daniel Kahneman's account of the two cognitive systems that govern human thought.

Kahneman on the fast, emotional System 1 that Voss insists actually drives every deal, no matter how rational the parties believe they are.

11

Nonviolent Communication

Marshall B. Rosenberg · Self-help

Nonviolent Communication is Marshall Rosenberg's framework for communicating in ways that preserve connection and address needs rather than triggering defensiveness.

Rosenberg defuses conflict by naming feelings and needs aloud, essentially labeling emotions with a gentler vocabulary than Voss's.

12

Predictably Irrational

Dan Ariely · Psychology

Predictably Irrational is Dan Ariely's examination of how humans make decisions that are consistently, systematically irrational — not random or arbitrary, but irrational in ways that follow patterns.

Ariely's experiments document the systematic irrationality Voss is exploiting every time he insists a negotiation is emotional, not logical.
