Study: Pizza Can Increase Productivity

It turns out pizza can be an intense motivator for people at work. Psychologist Dan Ariely offered four groups of employees at a company in Israel different rewards for productivity. One group was offered a $30 bonus, another pizza, another a compliment from their boss, and the last group was offered nothing.
