You can easily distinguish what is clearly an illusion or lie that is not going to work.

But you're right that recognizing which platform will actually work is very hard.

When it comes to economics one can find a plausable theory from a Nobel Prize winner to fit numerous competing platforms.

And social science isn't as solid as that.

I would say there are more equivocal problems than unequivocal and society looks for a leader to make gut feeling decisions. The only discriminator is the success of previous gut feeling decisions or even "it went wrong but it sounded good".
