The Jump-Juice Paradox
The study, conducted on rats, found that caffeine and other stimulants such as amphetamines don't actually raise motivation levels if they already worked hard -- only if they were lazy.
When presented with stimulants, the slacker rats, that typically avoided challenges, worked significantly harder when given amphetamines, while worker rats, that typically embraced challenges, were less motivated by caffeine or amphetamine.
