I run psychology experiments (motor control/spatial decision making) in VR and and its been a gamechanger in the last few years. Create your experiments completely in software to allow them to copied, modified, and distributed much more easily.
Imagine allowing a class of undergraduate students to participate in a version of Zimbardo's Stanford Prison Experiment and draw their own conclusions as to potential flaws in its methodology.
Or, as a philosophy student: allow students to engage in a real life rendition of Searle's Chinese Room thought experiment, where a student "competes" against his or her classmates and various versions of text generation algorithms from simple Markov chain generators, to OpenAI's GPT-2 and beyond.
