And speaking of psychology, what of virtual reality?

Yikes. Don’t like the look of this at all. How virtual reality environments can be genuinely scarifying. Of course waling between the towers of the original WTC on a rope in a virtual environment would be fairly scary (apparently they had to roll back the element where if you fell… you… gulp… fell). But it reminds me of Halloween Haunted Houses. East Wall has a particularly good one where a very large tent structure is kitted out with half light, ghouls, hands grabbing at you, assorted sound effects and so on. It probably takes six minutes at most to get through but the first time was visceral in a way I’d not expected having never done one before. Subsequent times it was less so. But that’s contained in a way. In a virtual environment literally anything can be thrown at you.
