The Top Things Every State Hates

I was looking at this list of the #1 thing hated in each state. My home state of Wisconsin hates "Traprock"
Arkansas hates cleaning. Colorado hates 'Nsync. 

See the full story.

Maybe I didn't see the details, but i'm wondering who they surveyed and how many?   How did they find that many people in one group who hate 'Nsync?  I asked a lifelong resident of Texas why the state hates sleeping with the window open?  She said "It throws off circulation of the air conditioning".  Is that true?
