I had this very discussion many moons ago with my sister in law, a research scientist. Her take, how we think is the product of a great many things, even diet. Of course the environment you grew up in plays a factor. She was looking and studying hormones, these are things we can not control willingly.
Enter the scientists who think they can.
that's how I felt reading this. there's no foundation for what they're saying, no rationalization as far as I've seen that it'll work. I mean I had fun reading this and wbw's article, it's a fun thought experiment, but I don't see how it'll actually work. Unless there's some translation or whatever, but then you're back at square one, except maybe slightly faster transfer of flawed communication.
And that's without getting into why you would want this, or how you expect to turn a really individualised society into one where enough people want this.
I mean I have arguments with my wife sometimes about whatever, and we reaaaaaaaaaally talk it out and at the end I feel like I understand her argumentation, why she feels that way, etc, and still disagree. Not seeing how literally thinking what the other person thinks will somehow improve my empathic abilities.
