The number one thing to understand about influence is that people make decisions for their reasons, not yours.

“When you try to influence others,” Sebastian Bailey and Octavius Black write in their book Mind Gym: Achieve More by Thinking Differently, “it is essential that you understand the other person’s reasons so you can use tactics that will work to persuade them, as opposed to tactics that would work on you.”

Okay, with that said, here are the nine primary tactics to influence others.

1. Reasoning

What Is It?

“There are three excellent reasons why contemporary art is a worthwhile investment. First . . .” The tactic we call reasoning, at its best, is the process of using facts, logic, and argument to make a case. Give Me an Example

“You should run the marathon next year. The training will make you fitter and healthier; it will give you something to focus on outside work, which you said you wanted; and you will raise money for a good cause, maybe that hospice you gave all your old clothes to for their fund-raising sale. It just makes sense.” When Is It Useful?

This tactic is useful most of the time. Reasoning is the bread and butter of influencing. The challenge is to support your views with relevant information and a coherent argument. Although reasoning requires more effort than some of the other tactics, it is much more likely to create your desired effect. Warning

When you present a view or position as if it is a fact (e.g., “This problem is going to take a long time to solve”) but without any evidence to back it up, then the reasoning is weak. Weak reasoning is the most common influencing tactic people use, but without the evidence to back up your view, it is far less effective.

2. Inspiring

What Is It?

“Imagine a world where …”

Almost the exact opposite of reasoning, the inspiring tactic focuses on the heart rather than the head. It appeals to emotions and suggests what could be possible, if only the other person were persuaded. Give Me an Example

Some of the most well-known uses of the inspiring tactic can be seen in political leaders’ speeches. Great examples are Martin Luther King Jr.’s “I Have a Dream” speech and Shakespeare’s “Once more unto the breach, dear friends” speech given by Henry V. These speeches don’t just ignore logical argument but defy it. Take this excerpt from John F. Kennedy’s speech about putting a man on the moon, with commentary from a skeptic in brackets. We choose to go to the moon in this decade and do the other things, not because they are easy, but because they are hard [Yeah, like that’s a good reason for doing something ; hey, I reckon we should paint the garden fences with a toothbrush and nail varnish because it’s really hard], because that goal will serve to organize and measure the best of our energies and skills [How so? Why wouldn’t feeding the starving in Africa or increasing world literacy do it just as well if not better?] . . .

For all the skeptic’s heckling, this speech helped mobilize a nation. The magic about inspirational appeal is that it touches our hearts by appealing to our values and our identity. Like falling in love, when the inspiring tactic works, nothing can beat it (certainly not a cynic).

When Is It Useful?

This tactic is especially useful when your rational argument is weak or unclear and you want a high level of emotional commitment. The inspiring tactic doesn’t tend to be used much in daily life, especially in the workplace, which is a shame because it’s a powerful way to persuade and excite.

Most of us have been seduced by this tactic as children (e.g., “It’ll make you big and strong when you grow up”), when watching TV (e.g., advertisements with young, sexy people having wild times drinking a particular brand of soda), or when we’re with friends who are hooked on a new craze (e.g., “You have to check out dune bashing: the surge, the speed, the heat, the views”).

Warning

It is not just what you say but also how you say it; the inspiring tactic demands conviction, energy, and passion. When deploying this tactic, a dreary demeanor will leave you floundering. Deliver inspiration like it matters more than life itself and you’ll be pretty much invincible.

3. Asking Questions

What Is It?

“Would you like to be rich?” Asking questions encourages the other person to make their own discovery of your conclusion (or something similar). Give Me an Example

I am walking through the airport when a woman with a clipboard approaches me from in front of a large advertising board and asks, “Do you have a credit card?” I utter a dismissive “Yes” and keep walking. “Do you get airline miles with your card?” she persists. “Yes, I do,” I reply, slightly irritated, and carry on walking. “Do you use your airline miles?” The truth is I don’t, but I’m not going to get caught up in this conversation. “A bit,” I reply, but my walking slows. “Would you rather have cash?” I stop, turn, and look at her for the first time. “Do you have five minutes to fill in a form to get a credit card that gives you cash?” she asks. In five questions I have been persuaded to do something I haven’t done in over a decade: switch to a new credit card. When Is It Useful? This is a great tactic when it is important that the other person feels responsible for the outcome. In coaching and counseling, for example, a course of action or therapy is much more effective when the other person believes it was their idea rather than when they grudgingly give in. Asking questions is also useful when you’re trying to persuade someone who has more power than you— maybe your boss (“Do you think I’m overdoing it?” “Do you struggle with work– life balance? How do you deal with it?”) or your client (“Are you happy with the gold service? Or do you ever wish you had the platinum?”). Warning

This is one of the hardest tactics to use because it is impossible to know how the other person will respond. If the questions are too broad, then you are likely to veer off course; if they are too narrow, the other person will spot what you are up to and may refuse to cooperate. But while most of the other tactics get weaker if they’re used too much, asking questions is a tactic that has an extended battery life— it’s effective time after time.

4. Cozying Up

What Is It?

“You’re a smart guy.” If you feel positive toward someone, you are much more likely to agree with them, and you almost always feel positive toward someone who makes you feel good about yourself. This is the cozying up tactic. Give Me an Example

“Hi, Sandra. You’re looking well. I heard from Mark that you did a great job on the Johnson case. Not an easy situation— well done. I have a challenging case coming up in October and am pulling together a top-level team to work on it. Would you be interested?” When Is It Useful?

Cozying up is a particularly good tactic to use when you’re trying to influence people with less or the same level of power as you, because they are likely to value your views. Many of us use it on our partners (“Darling, you look like a million bucks”), our friends (“I know you are someone I can trust”), and our clients (“You’re the sort of person who will really appreciate this— because you’re smart”). The danger with cozying up is that if you’re too obvious when using this tactic, you’ll have the opposite effect (“You’re only saying that because you want me to do something for you”). As a result, some people avoid it altogether. They are missing out. A less risky approach is to leave time—sometimes even several days— between making someone feel good about themselves and trying to persuade them. Warning

Using cozying up on someone who clearly has more power than you can look like sucking up. So, unless you know what you are doing, be mindful about how much kudos you’re sending out into the world.

5. Deal Making

What Is It?

“If you pick me up from the airport, I will . . .” Deal making is when you offer or give another person something in return for their agreement with you. It may be explicit, but it doesn’t have to be. Give Me an Example

“I promised a friend I would walk his dog while he was on vacation. Then tonight I was offered Beyoncé tickets at the last minute. I’ll buy you dinner if you come over and watch the dog while I’m at the concert.” When Is It Useful?

Deal making is useful when you want to increase the odds in your favor and don’t mind giving something away in return. Sometimes it is necessary to be up front (“If you help me paint the bathroom, I’ll cook dinner every night next week”). At the same time, the deal can work better when the connection is only implied (“Sure, I’ll introduce you to my sister,” and then twenty minutes later, “Can you really get me into the VIP section at the golf tournament?”). Often deal making is most effective when the connection is all but invisible, like it’s something you would have done for one another without a deal. Warning

This tactic works by appealing to a desire for fairness. Some people can “take, take, take” without feeling any remorse or indebtedness (or they may just think you’re a generous fool). Deal making won’t work with this type of person unless you are very up front about the terms of the exchange.

6. Favor Asking

What Is It?

“Can you help me out?” Favor asking is simply asking for something because you want or need it, but you’re not offering anything in return. Give Me an Example

“My guest speaker has just pulled out of the event I’m organizing next week. All I can say is that I’d be eternally grateful if you’d be willing to step in and give a speech to my group.” When Is It Useful?

This tactic works well only when the other person cares about you or their relationship with you. If used sparingly, it is hard to resist. Warning

The person you ask for a favor might feel that you owe them one in the future. If you think they do, make sure you “pay back” the favor or you won’t get such a positive response next time.

7. Using Silent Allies

What Is It?

“Everyone who has read this book so far …” The use of silent allies invokes other people, who are generally similar to the person you are trying to persuade, to make your case (“All professional runners train this way, so you should too”). Give Me an Example

The advertising slogans “Nine out of ten dentists recommend …” and “America runs on Dunkin’” are classic examples of this tactic. Movie reviews and quotes from satisfied customers are also common examples . Outside of advertising and marketing, the silent allies approach is often used in the workplace, where you might hear comments like “All the best graphic designers use a Mac.” In social situations, you might hear “All the cool kids are wearing these jeans, and they’re the top-selling brand.” The best silent allies are those whom the person you are trying to persuade naturally associates with, such as professionals in their own industry or people with similar interests or beliefs. When Is It Useful?

One of the most powerful ways to persuade teenagers to do anything is to show them that their peers, especially the cool ones, are doing it already. The silent allies tactic also works in business by, for example, referring to best practice models or a list of past clients. If the person you are trying to influence is concerned about risk (and most people are, deep down) or is anxious to fit in, then this can be your winning tactic. Warning

Some people actually prefer to be contrary (“I only like underground bands”). Entrepreneurs, for example, are rarely dissuaded from trying something because no one has done it before. They actually see it as a potential benefit.

8. Invoking Authority

What Is It?

“It’s our policy not to refund cash.” The invoking authority tactic is used from a position of power or by appealing to a rule or principle. It doesn’t matter whether the authority invoked is formal or implicit, so long as it is recognized by the person you are trying to influence. Give Me an Example

“I won’t work for you unless we sign a contract” is an explicit approach to influence that not only appeals to the rules but also creates them. “I won’t take business calls between the hours of five P.M. and seven P.M. because that is dinnertime with my family” is an approach to influence that creates boundaries based on principles. When Is It Useful?

The advantage of invoking authority is that the tactic is quick and straightforward . The downside is that it is more likely to lead to compliance than commitment. It’s better to invoke authority as a last resort rather than use it as your opening gambit, unless you are in a rush. Authority can, however, make a positive impression on someone who abides by similar rules or lives by similar principles. Warning

If you try to persuade using this tactic and don’t succeed, then you don’t have many other options left (mainly the forcing tactic, detailed next). You are also likely to have damaged a relationship. And like using silent allies, this tactic can have the opposite effect from the intended one. Think of Dirty Harry being told he is being pulled off a case, only to carry on his investigations anyway. Or Julia Roberts in the movie Erin Brockovich refusing to bow down. If the person you’re trying to influence doesn’t agree with your rules or principles, using authority can have a quick and extreme impact on your relationship. Be warned, this tactic is a bit like drawing a line in the sand.

9. Forcing

What Is It?

“Do it or else.” The forcing tactic involves engaging in assertive behavior, such as threats and warnings. Give Me an Example

“Eat your vegetables or you’ll be going straight to bed.” “Love me or leave me.” “The last person in your job didn’t last very long; we wouldn’t want you to make the same mistake.” “The more time you spend arguing about it, the less time you’ll have left to do it.” When Is It Useful?

Forcing is used when you want something done fast. Therefore, it’s ideal in emergencies. Warning

Because forcing is relatively easy to adopt and usually delivers short-term results, like compliance, it gets used a fair bit, especially when combined with using authority. However, relationship breakdowns can often be traced back to uses of the forcing tactic. Almost like smoking cigarettes, the immediate damage appears minimal, but the long-term effects can be terminal; and even if you give up using this tactic, it could be too late, so it’s probably best not to start. Using the forcing tactic can also be quite addictive, because it gives the user a sense of power when it gets results. Only employ forcing when everything else has failed.

Remember people change their mind for their reasons not yours. If you’re not effective, it’s probably because you’re looking at things through your lens and not theirs. Continuing to give the same arguments in the same way only solidifies resistance even more. So the next time you’re trying to convince someone of something you’ve already tried to change their mind on, trying picking a different approach. Better yet, pick three or four and use them in combination. Tactics work better when employed together.
