![In 2007 a Harvard psychologist set out to test her theory that "Mind-Set Matters."¹ She recruited 75 female maids² working in
different hotels to participate in her study, and informed 41 maids (randomly chosen) that the work they do satisfies the Surgeon
General's recommendations for an active lifestyle (which is true), giving the maids examples on how their work qualifies as good
exercise. The other 34 maids were told nothing. After four weeks, the exercise habits of the two groups had not changed, but the
informed group had lost an average of 1.79 lbs (s = 2.88) and the uninformed group had lost an average of 0.2 lbs (s = 2.32). The
data are stored in MindsetMatters. Based on this study, does "Mind-Set Matter"? In other words, for maids, does simply thinking they
are exercising more actually cause them to lose more weight?
