The secret to eating less and being happy about it may have been cracked(有裂缝的,声音沙哑的) years ago—by McDonald’s
The researchers, led by Martin Reimann, carried out a series of experiments to see if people would choose a smaller meal if it was paired with a non-food item.
They found that the majority of both kids and adults opted for a half-sized portion when combined(组合) with a prize
the promise of a future reward was enough to make adults choose the smaller portion
this was as effective as a tangible gift in persuading people to eat less.
The fact that participants were willing to substitute part of a food item for the mere prospect of a relatively small monetary award is interesting
He theorizes that it is the emotional component of these intangible prizes that make them effective
vaguely-stated possibilities of winning a prize were more effective than options with hard odds included
