This study will learn things about how a biased sample of the population answer choices in a simple game depending on the context given; extrapolation from that basis to anything wider, for example the notion that the players view these choices as "moral" requires far more work. It is well known that people use games for escapism, so it does not seem straightforward that the decisions they make in a game always map cleanly to their real opinions just because you put "moral" in the title of the game.

Its also worth keeping in mind that moral decisions have been explored for quite some time, and the novelty here is mainly the mode with which the population is sampled.
