This is probably only the case in agricultural areas where humans are often working in the area. In my case I hunt Wildlife Management Areas and deeper woods types of areas that don't see much human intrusion except during hunting season. So in the case of these deer, you would think they are spooked by human scent because it is not a norm and is only present during hunting season.

I always try go scent free. Why risk spooking a buck out of the area?
