9 elements you need to be more influential and persuasive at work and in business

• Dr. Amanda Nimon-Peters studied persuasion to uncover 9 principles that can help your career.
• To influence a decision in favor of the outcome you'd like, present it as the normative choice.
• People are influenced by whether we feel a person is like us, so emphasize your similarities.

Influence and persuasion skills are highly desirable for all businesspeople, and especially for entrepreneurs, whose livelihoods depend on the outcome of certain momentous decisions. The good news here is that influencing skills can be learned — and improved — with the right methodology.

If you've ever considered improving your powers of persuasion, you may have come across Robert Cialdini's "The Psychology of Persuasion," or Dale Carnegie's "How to Win Friends and Influence People." While these books are great, they were also both written in the in the 20th century — I don't have to tell you that the world of work has changed enormously in the past few years, let alone since 1984.

Today's business professionals have been missing a model for influence at work specifically designed for the 21st century. As a business school professor, I sought to fix that problem. Eighteen months ago, I examined the last four decades of behavioral science research on the factors that influence people's decisions and actions. As a former entrepreneur and corporate executive in the Middle East, it was my goal to include research from Asia, Africa, and the Middle East, as well as studies from Europe and the US.

The result is my book, "Working With Influence: Nine Principles Of Persuasion To Accelerate Your Career." It is based on more than 200 peer-reviewed journal articles, revealing nine universal principles for increasing your influence at work. These nine principles are organized into three sets of three to ensure they are easy to learn and remember: principles one to three are people-related, principles four to six are perception-related, and principles seven to nine are behavior-related.

Principle #1: Status

In all cultures, people who have higher status are given preferential treatment. The key to gaining influence via principle one is to understand that status rankings are often done subconsciously, so think carefully about how you present yourself. The key is to avoid mentioning factors that reduce your status, like a lack of experience in one specific area, and instead make others aware of any experience, qualifications, or past successes you have, such as previous work experience at a big-name company. Be careful that the words you use are not simply the first ones that come out of your mouth.

Principle #2: Social imitation

Our choices are heavily influenced by those of people around us or like us. Numerous studies have shown that when people receive information about what others have done in the same situation, they modify their own preferences in the same direction. The effect is stronger the more the target audience identifies with the referent group. To influence a decision in favor of the direction you propose, present the option you want people to choose as the standard or normative choice for the decision-maker's social grouping.

Principle #3: Affiliation

Our decisions about people are influenced by whether or not we feel a person is like us or part of our in-group. Research data shows that decision-makers can feel affiliation towards someone who graduated from the same school, who has friends or colleagues in common, or even someone who has the same first name. Creating a sense of affiliation between yourself and other people can help to tip decisions in your favor during an interview or a client meeting, or when you are seeking help and resources.

Principle #4: Value-framing

In our day-to-day communication, we often fail to express the value of our work in terms that are inherently valuable. For example, we say "This is a great solution," instead of "This solution can reduce the hours your employees spend on data processing by more than 50%." Both statements can be true, but only the second statement is expressed in units that are inherently meaningful to a customer. Value framing works because the tendency to judge value in relative, rather than absolute, terms is universal in humans.

Principle #5: Effort

Humans globally behave as if they're programmed to expend the absolute minimum seconds or calories of effort to achieve a given outcome, unless they have a very good reason to work harder. This is a facet of influencing we rarely consider. If you control the effort involved, you control the likelihood it'll be done. Don't want people to do something? Ensure that it's a lot of work, and you won't have to say "no." Want people to do something? Make it as easy as possible, and people will often comply, just because you ask nicely.

Principle #6: Reasoning

Studies show that when people at work attempt to influence others, the most common tactic is rational persuasion, i.e. providing logical reasons. Those same studies also show this isn't very effective. Human decisions are far less influenced by logical reasons than by the prospect of reward. To use principle six, generate an influential reason by tapping into emotion. What would make someone feel, rather than think, that your idea is a good choice?

Principle #7: Inertia

In many situations, human behavior occurs in a predictable sequence, as if actions were being driven by an invisible force, such as inertia. Perhaps you have a specific sequence when you enter your front door — keys on the rack, drink from the fridge, feet on the coffee table, TV on! As Bruce Lee suggested, it's often easier to go with the flow of water than to fight against it. Given what is most likely to happen, what is your best move?

Principle #8: End-goal focus

Imagine you're on a motorboat, attempting to reach a faraway-shore with a dwindling source of fuel. The more you waiver from side-to-side, the less likely you are to reach your goal. The fuel analogy is highly relevant, because people have limited energy with which to make decisions. Focus your energy and efforts against achieving one outcome — not against trying to win all arguments at the meeting. A 16th-century proverb says: "If you try to run after two hares, you will catch neither."

Principle #9: Execution

Planning and executing that plan aren't the same thing. The key to applying to principle nine is to practice the aspects of execution and delivery most strongly linked to persuasion — an upright-posture, familiar words, and a voice that matches the emotion of the message. Practicing micro-adjustments in your execution must be done in advance, because it's too hard to focus on what you're saying and how you are saying it, at the same time.

When it comes to influence at work, you don't have to be the best influencer there ever was. Your goal should be to develop your skill so that your success improves relative to what it has been. Aim for steady improvement!
