One $2013$ study askedAlmost $2500$ workers to analyze medical images for objectives of interest. $80$ one group that though Work would be disregarded, they told the other group that objectives were "concerous tumor cells."the workers were paid per image analyzed. The latter group, or "meaning" group,spent more time on each image, earning $10\%$ less, on average, then the "discard" group$-$but the Quality of their work was higher. What can we in for from this?
