We Americans LOVE our surveys! A recent study, conducted at the University of Innsbruck indicates people who prefer their coffee black are more likely to have psychopathic or sadistic tendencies than those who take cream and sugar. More than 1,000 people were questioned about their flavor preferences. They were then asked to take 4 different tests evaluating various personality traits. Those who preferred bitter flavors were reportedly more prone to antisocial behavior. The survey, reported by rare.us, indicated those who sweeten and cream their coffee have more agreeable personality traits than black coffee drinkers. My Mom uses half & half, and stevia. My fiancee uses half & half & honey. She thinks I'm weird because I don't sweeten mine. I prefer a little milk, preferably skim or 1%.
