I don’t buy it.
Turkeys are not capable of the complex thought proccess it would take to identify a blind as a threat.
I think as turkey hunter we all assume that something was wrong with our setup, blind, calling, or decoys. Truth is sometimes it is something we’ve done, and sometimes a branch moving from the wind could send them running. I don’t know as much as some of you, but from what I’ve seen in the times I’ve hunted is a turkey will hang up on anything. A branch, a puddle, a shadow, or even an immaginary line, yet we assume they are capable of associating a stationary object with danger? I’m not drinking that cool-aid.
I think some are giving these birds a little to much credit. They are a basic animal that do have survival instincts, but those instincts are pretty much limited to breeding, food/water, and roosting. Of course, Im not sure I have enough experiance, so its just my opinion.
