"blind test" doesn't work.

Please explain.

Based on what I understand from this presentation:

http://www.ted.com/talks/malcolm_gladwell_on_spaghetti_sauce...

Gladwell means that people don't always know what they want (or wont be able to tell you).

Always is the operative word in that sentence. Most of the time they know quite well what they want, sometimes they don't.
