For this study [...] volunteers who had been kept awake all night were divided into two groups. All were asked to chew gum in the morning, but one group got a plain wintergreen placebo, while the other chomped on gum laced with 200 milligrams of caffeine, or about the same amount that's in two cups of black coffee. The participants were then put in situations where researchers "encouraged them to go along with a lie in order to earn some extra money," Christian says. "We tried to replicate a situation where a boss or a peer was pressuring them to cut ethical corners at work."
The results: Those who got the extra boost of caffeine consistently balked when researchers urged them to cheat, while those who were just exhausted — and had chewed the non-caffeinated gum — showed a marked willingness to cast conscience aside and go along with the deception.
-This study another way: sleep deprivation turns you into a shithead, which, sure. "Two other suggestions," says Fortune. "Put in nap rooms at the office and don't skimp on the free coffee." If you work at home, the world is your nap room! [Fortune]
