Hmmm.
Well, I'm not sure if the study was ethical or not. The article doesn't get into the details about it. However, I see nothing wrong with trying to discern how good or bad nutrition plays a role in preparing people to learn and/or make economic contributions to the community.
I also think that human beings are motivated by different things, or not motivated. Nutrition is but one of those variables that go into the mix that determines a person's ability to work, be healthy, etc.
