Good point. I'll try to add a little qualifier.

I would say that sales is definitely a creative task (but you're right that's the important question w/r/t Ariely). There is a rote aspect to working the phones, or keeping records, but sales is a performance skill that requires a lot of thought about strategy, rhetoric, timing, etc. etc. By no means is it rocket science (I wrote a bit about that here: http://www.fogcreek.com/guide/The-most-basic-things-your-com...), but there is a lot to consider and get good at.
