People judge others based on 2 criteria on first meeting

People are quick to size you up in seconds as soon as they meet you. But what exactly are they assessing?

Harvard Business School professor Amy Cuddy has been studying first impressions alongside fellow psychologists Susan Fiske and Peter Glick for more than 15 years, and has discovered patterns in these interactions, reports Business Insider.

According to the Business Insider, Cuddy in her new book 'Presence' says people quickly answer two questions when they first meet you:

"Can I trust this person?"

"Can I respect this person?"

These dimensions are referred to as warmth and competence respectively by psychologists and ideally you want to be perceived as having both.

Interestingly, Cuddy says that most people, especially in a professional context, believe that competence is the more important factor, reports the news portal Business Insider.

After all, they want to prove that they are smart and talented enough to handle your business.

But in fact warmth, or trustworthiness, is the most important factor in how people evaluate you.

"From an evolutionary perspective," Cuddy says, "it is more crucial to our survival to know whether a person deserves our trust." It makes sense when you consider that in cavemen days it was more important to figure out if your fellow man was going to kill you and steal all your possessions than if he was competent enough to build a good fire.

While competence is highly valued, Cuddy says it is evaluated only after trust is established. And focusing too much on displaying your strength can backfire.

Cuddy says MBA interns are often so concerned about coming across as smart and competent that it can lead them to skip social events, not ask for help, and generally come off as unapproachable.

These overachievers are in for a rude awakening when they don't get the job offer because nobody got to know and trust them as people.

"If someone you're trying to influence doesn't trust you, you're not going to get very far; in fact, you might even elicit suspicion because you come across as manipulative," Cuddy says.

"A warm, trustworthy person who is also strong elicits admiration, but only after you've established trust does your strength become a gift rather than a threat."
