Weir finds the conscientious earn more
"Being conscientious can be worth $158,000" - UPI. 3/29/2011.
David Weir and colleague Angela Lee Duckworth examined earnings, savings, and self-evaluated personality traits of about 10,000 US adults, age 50 and older. They found those at the 85th percentile for conscientiousness earn about $1,500 more per year than the average American, which amounts to about $96,000 more in lifetime earnings and $158,000 more in lifetime savings.
