I've been reading quite a bit about emotional intelligence lately.

Partly, I'm trying to up my game and be more aware of how body language, my tone and eye contact, and even how much I am paying attention can send hidden messages.

Most of the research I've seen suggests your IQ stays fairly constant and doesn't change even if you keep educating yourself, but your Emotional Intelligence Quotient (or EQ) can change with a little due diligence, a little effort, and a little...math.

To help, I've started to pay more attention to the details. (That's right, as a highly analytical introvert I have figured out a way to use data to help me in social situations.) Here are a few stats and figures that can help you gain a higher EQ rating.

65% to 93%: The percentage of impact non-verbal cues carry over spoken cues

10,000: The number of non-verbal cues you send out every minute during a conversation

4 to 8 feet: The distance most people prefer for formal business interactions

1.5 to 4 feet: The distance most people prefer for casual business interactions

80%: The degree of accuracy experts say they can predict how a negotiation will turn out based on non-verbal cues.

55%: The percentage of non-verbal cues that are related to gestures and posture

12.5 times: The number to multiply your non-verbal cues like attitude and feelings against your verbal cues to determine which carry more weight in a conversation.

7%: The percentage of communication that is actually verbal

38% The percentage that is related to tone (not what you say but how you say it)

2.5 seconds: How long it takes to say the average sentence

250,000: The number of facial expressions we can recognize

10-11 minutes: The total amount of time you spend per day speaking on average

87% Percentage of accuracy when women are reading expressions

42%: The accuracy when men are reading the same expressions

90%: The percentage attributed to emotional intelligence versus other factors for the best leaders in business compared to average leaders

$190 million: The amount the US Air Force saves when pre-screening pararescue jumpers for high emotional intelligence each year

24%: The percentage increase in sales at Sheraton Hotels after running an EQ program
