Hey class,

This is a great Ted talk by a "ad guy" Rory Sutherland that speaks on perception and the power of perceived value versus real value. I think he is funny and worth taking 16 minutes to watch but the following time markers address class topics:

2:13 - Talks of placebos and the concept of "placebo education"
3:13 - A historical account of how perceptions of potatoes changed market demand
6:44 - Perceived value trumps material value of jewelry
11:55 to 14:20  - A couple great video advertisments about a campaign that was based on pure perception and humor.

Enjoy!
Rob
