We have all slacked off at one point in time in our lives. There are numerous causes that lead to slacking, or doing sub-par work, or the bare minimum needed to get by, but now there are research findings, from the Journal of Personality and Social Psychology, that say that slackers outperform hard working, high achievers in certain areas, for specific reasons.
A new study suggests that hard, motivated workers generally excel at certain tasks, WHEN they are reminded of the benefits or optimal outcomes of their hard work. That makes sense. If you dangle the carrot in front of the hare before the race, that hare will probably run faster than if you didn't tell him he was working for his dinner.
