A recent study claims that pizza is a bigger motivator than cash and can make people more productive at work when used as a stimulus. The discovery was made by psychologist Dan Ariely and detailed in his book Payoff: The Hidden Logic That Shapes Our Motivations.
The study stated that the promise of pizza increased productivity by 6.7 percent on the first day. That means that employees dreaming of cheesy, pepperoni sprinkled deliciousness worked 6.7 percent harder! As if you really needed a reason to eat more pizza!
