When Daniel Goleman published the book Emotional Intelligence in 1995, few had heard of the term. In academic circles, it was a new concept - a theory formed by two psychologists, John D. Mayer and Peter Salovey, that posited that just as people have a wide range of intellectual abilities, they also have a wide range of emotional skills that profoundly affect their thinking and actions.

Fast forward to today. You'll find references to emotional intelligence just about everywhere, most of them positive: how emotional intelligence can make you a better leader, a better employee or even a better spouse or parent.

What you don't see very often are references to the negative aspects of emotional intelligence. But it's important to remember that emotional intelligence, much like "traditional" intelligence, is not inherently virtuous. It's a tool.

In other words, emotional intelligence can be used for good or evil.

This is the dark side of emotional intelligence: using one's knowledge of emotions to strategically achieve self-serving goals. Much as a person possessing a brilliant intellect could become an accomplished detective or a criminal mastermind, one with a superior emotional quotient has a choice between two very different paths: using their influence to help or to harm.

Scientists have become more interested in this dark side in recent years. For example:
  • In 2010, a group of scientists found that individuals who demonstrated certain narcissistic traits (in essence, a pervasive pattern of grandiosity, self-focus and self-importance) made better first impressions on their peers by using humor and charming facial expressions. That is to say: people with their own interests at heart are more talented at gaining others' support, at least at first.
  • A 2011 study indicated that "Machiavellians" (people who show a tendency to manipulate others for personal gain) who rated high in knowledge of emotion-regulation were more likely to engage in deviant actions, such as publicly embarrassing someone at work.
  • A 2013 study found that those who tended to exploit others for personal gain were also good at reading those peoples' emotions, especially negative ones.
Such attempts to influence and manipulate your emotions are very common place. From politicians attempting to win your vote to companies attempting to win your dollars, everyone works hard to pull at the heart strings.

So, how can you deal effectively with others' attempts to manipulate your emotions, to avoid making unwise or harmful decisions?

One of the best ways is by working to increase your own emotional intelligence.

For example, your capacity to accurately perceive others' abilities to persuade, influence or even manipulate people can serve as a self-defense mechanism - a type of "emotional alarm system" that alerts you to the fact that someone is attempting to manipulate your feelings, to get you to act in a way that is not in your best interests or that conflicts with your values and principles.

If you notice someone is trying to inspire fear to move you to drastic action, your alarm system should go off. Instead of quickly jumping on the bandwagon, this alarm should move you to research facts and consider opposing opinions before passing judgment or making a decision.

But what if someone is intentionally trying to get you riled up, angry, frustrated? Maybe it's a competitor who tries to throw you off your game or an online troll seeking attention or entertainment.

How you choose to engage with these people depends much on the situation and what you hope to accomplish. But Dr. Drew Brannon, who has spent over a decade advising high-level athletes, teams and coaches on how to deal with trash talk, teaches his clients to have a plan, a pre-established routine of how to respond. The goal is to form a mental cue that blocks out the other person's attempt to manipulate or distract, and allows you to focus your attention on moving forward.
