Influence for negotiators

Negotiate with the science of influence.

The Influence Assessment is for anyone who negotiates contracts, prices, salaries or partnerships. It shows which principles of influence you use at the table, which ones you drop when the pressure rises, and what to do about both. When you know how you naturally persuade, you walk in with a plan instead of relying on nerve.

What makes it different

Advice built on how you already negotiate.

No two negotiators win the same way. One builds a relationship before the first offer; another wins on preparation and a firm opening number. The assessment shows which principles you rely on when the other side is deciding, so the advice fits how you actually negotiate.

See the seven principles of influence.

Your strongest principle and your biggest gap.

See which principle you lean on to get agreement, and which one you leave on the table.

A name for why your good deals go well.

Most negotiators can't say why one deal closed on good terms and the next one didn't. Your result puts a name on it.

Plain, direct advice.

The full report tells you where your habits help you hold your position and where they cost you.

Where your style works against you.

Concede too early and the other side expects more. Hold every point and they stop trusting you. The report shows the risk in your pattern.

Things to try in your next negotiation.

The full report gives you words to try and a 30-day plan, so you practice on deals that are open now.

Free to start.

Your result is free and appears as soon as you finish. The full report is $49, and you decide after you see your result.

What's inside

Where each principle shows up in a negotiation.

Your result covers all seven principles of influence. Here's what you get.

  1. Your strongest approach.

    The principle you reach for first when you need the other side to agree.

  2. All seven principles, in plain words.

    Reciprocity, liking, social proof, authority, scarcity, commitment and consistency, and unity, plus contrast, the amplifier that changes how a number reads.

  3. Your biggest gap.

    The principle you use least. Hold it up against the last deal where you gave away more than you meant to.

  4. Principle by principle, in the full report.

    Where each one helps you, where it hurts you, and words to try.

Your influence across a negotiation. Each moment calls for a different principle:

  1. Before the table

    Unity: find what you and the other side truly share, and set the agenda before anyone names a number. Dr. Cialdini's book Pre-Suasion covers this moment.
  2. The opening

    Authority and contrast: show what your number rests on, and know that the first figure on the table frames every figure after it.
  3. Concessions

    Reciprocity: a real concession invites one back. Trade each one for something; don't give it away.
  4. The close

    Consistency and scarcity: build on what they already agreed to, and name what they lose by walking away, if it is true. Scarcity in negotiation

Who it's for

For negotiators at every level.

Whether you close deals every week or face one big negotiation this year, the assessment starts with how you negotiate today.

People who negotiate for a living.

Deal leads, buyers, procurement and partnership managers: see how you influence the other side at every step, from preparation to the signed terms.

People who negotiate now and then.

A salary, a lease, a supplier contract. You'll know which principle you lean on and where you give ground, before the conversation starts.

People who've read Influence.

You know the principles. This shows which ones you actually use when the other side pushes back.

People new to influence.

Learn the seven principles and see where you stand on each, in one sitting.

Negotiators and authors on the research behind it.

  • “Dr. Cialdini’s book was the foundation for much of what we spearheaded in the FBI that moved professional negotiators towards becoming crisis interveners. We copied very heavily from Cialdini’s book. We looked at ways people gain influence with another and it is all about relationship building, earning trust and demonstrating a genuine interest in their issues and concerns.”

    Gary NoesnerFBI Negotiator & Author

  • “Anyone who wants their abilities in communication or negotiation to be at their highest level has to read Robert Cialdini's book. Your knowledge base is simply incomplete without it.”

    Chris VossAuthor, Never Split the Difference

  • “Whether you seek to boost sales, strike a better deal, or improve your relationships, 'Influence' offers scientifically tested principles that can change your life.”

    Daniel ShapiroFounder, Harvard International Negotiation Program
