Virtual superpowers encourage real-world empathy:

With a whoosh of air, the subjects left the ground – either controlling their flight by a series of arm motions, like Superman, or as a passenger in a helicopter. As they scoured the city, wall-mounted speakers gave the impression of wind whistling by; powerful speakers in the floor produced vibrations to simulate riding in a helicopter. The experiment was set so that two minutes into the simulation, no matter what mode of transport, the subject found the sick child.

After removing the virtual reality goggles, each person then sat with an experimenter to answer a few questions about the experience. This questionnaire, however, was a ruse: During the interview, the experimenter would "accidentally" knock over a cup filled with 15 pens. She would wait five seconds to see if the subject would help her pick them up, and then begin collecting the pens, one pen per second, to give the person another opportunity to come to her aid.

The people who had just flown as Superman were quick to lend a hand, beginning to pick up the pens within three seconds. The helicopter group, however, picked up the first pen, on average, after six seconds (one second after the experimenter began picking them up herself).

The superhero group not only pitched in first, they also picked up about 15 percent more pens on average. While everyone who flew like Superman picked up some pens, six participants who rode in the helicopter failed to offer any help at all.

The conclusion:

"If we can identify the mechanism that encourages empathy, then perhaps we can design technology and video games that people will enjoy and that will successfully promote altruistic behavior in the real world."

Seems a bit dark-artsy, using a known cognitive bias, even for good ends, but probably nothing out of the ordinary.
