The study showed a difference in subsequent behavior between the people who chose to take the role of the hero and those who chose to take the role of the spectator.
A fine example of how study results tend to be either obvious or false.
...and taxpayers were forced to pay for that.
Okay, I don't know if this is a unicorn post or what, but:
1) The subjects didn't choose their role. The study was about the effect of media on people's altruism. Allowing them to choose their role would render it pointless.
2) There's nothing obvious about the role of media on your altruism. And such a study could eventually help people become better people.
3) Nowhere does it say that this study was paid for using government money. It was conducted by Stanford University. The source of the funding could have been a private grant, tuition and fees, or whatever. No matter where the funding came from, it probably wasn't a very expensive study. I suspect they already had the VR and sound equipment in their media department, and other than that, you only need some volunteers and some paper to write down the results. And even if there were some government funding involved, it was used to pay for helping to educate students and add to the body of human knowledge--that is, it was used precisely for what universities are
supposed to use funding for. So what's the problem? Are you under some misguided impression that you, representing the "taxpayers", have personal ultimate authority over deciding what research is and isn't worthwhile, with veto power over the university's leadership who does this sort of stuff for a living?
