Some random genius

Some random genius named Sarah Walker wrote this gem the comments of a TED talk:

The trouble with natural happiness is that it can be so short-lived. [. . .] Synthetic happiness on the other hand can be a choice of a state of mind and can therefore be more permanent. I think people have trouble with the words 'synthetic' and 'natural' where emotionally speaking, 'natural' is seen as superior. If we were to change the words to 'intrinsic' and 'extrinsic' maybe people would have an easier time accepting the notion that happiness can be a [choice]

I suspect she is right. Maybe Dan Gilbert or some marketing students will do an experiment.
