New York University psychologist Gabriele Oettingen studied women enrolled in a weight‒reduction program trying to lose a few pounds. In the study, the participants used positive thinking ― imagining themselves reaching their goals ― as a motivator. The results weren’t so positive. “A year later, I checked in on these women from the weight‒loss study,” Oettingen writes in the New York Times, and “the more positively women had imagined themselves in these scenarios, the fewer pounds they had lost.” As the above study and others of Oettingen’s found, positive thinking makes people feel comfortable with their present state. Too comfortable. Dreaming of the future “can drain you of the energy you need to take action in pursuit of your goals,” she says. “Positive thinking fools our minds into perceiving that we’ve already attained our goal, slackening our readiness to pursue it.”
What does "checked in on" mean? How does it differ from "check in"?
"I checked in these women" doesn't make sense in the context.
"I checked in on" and "I checked on" mean more or less the same.
