In one experiment, Wiseman asked people to self identify themselves as lucky or unlucky. Then he gave his test subjects a newspaper. “Count the number of photographs inside”, he told them.
There were 43 photographs.
On average, the unlucky people took 2 minutes to count them all. The lucky people? Seconds.
The lucky people noticed the giant message that took up half the second page of the newspaper. It said, “Stop counting — There are 43 photographs in this newspaper.”
“Just as effort alone can’t deliver results, praising effort isn’t enough to help a child develop a love for the challenge of learning.”
