“University of Hawaii researcher Lou Herman ‘has proved that dolphins are capable of complex problem solving, demonstrating prodigious feats of learning, memory and creativity,’ reports Reader’s Digest. ‘One well-known anecdote involves a clever aquarium dolphin who was rewarded by his trainers for retrieving one piece of garbage after another. It turns out that, in order to maximize his fishy rewards, the dolphin had stashed an entire newspaper at the bottom of the tank and was tearing off one small piece at a time.’”

“Economists... conducted an experiment at a poor, minority school district near Chicago where they randomly assigned some teachers to receive end-of-year bonuses based on student improvement, while other teachers received upfront bonuses that could be revoked at the end of the year if student improvement was below average.... the only difference was the timing of the bonus. There were ‘large and statistically significant gains’ on math test scores when bonuses were paid upfront, but not when bonuses were paid at the end of the year.... the prospect of having to give back money they had already received was more motivating for teachers than the prospect of getting money.”
