The effects of coffee on our health and productivity are debated ad nauseam, but your need for that 10:00 a.m. double espresso each morning might say more about you as a person than it does about your wellbeing.

Recruiter.com dove into the heaping research on both sides of the argument to find out if coffee-drinkers are, in fact, more incline to have Type-A personalities.

“Consider what is perhaps the most obvious conjecture: that heavy coffee-drinking is somehow related to ‘Type-A’ personalities—variously described as competitive, aggressive, clock-chasing, impatient, bad-tempered, ambitious, workaholic go-getters. In terms of popular stereotypes and iconic images of time-pressed young professionals juggling a coffee while racing back to the office or to a high-powered meeting, it would make sense that coffee is their high-octane gasoline.”

What Recruiter.com found, however, was pretty inconclusive. Although one study suggests a connection between Type A personalities and caffeine consumption, there’s also plenty of anecdotal evidence to suggest otherwise. (How many aggressive people do you know who abstain coffee? Probably quite a few.)

Whether or not science can find a connection between personality and caffeine, many coffee drinkers at least believe that their holy bean holds the secret to performing better at work. According to a 2011 survey conducted by Alterra Coffee Roasters, one in five people surveyed said their work would suffer without their caffeinated friend, and 30 percent believe it helps them remain focused.

I don’t think my work would suffer without coffee. However, my coworkers might, and that’s not fair to them. For their sake, I’ll keep the coffee pot on and my cup full.
