I personally think this way after yrs of using trying and NOT using them
there are SO many variables involved in calling of deer that there is NO clear answer on if they work to help or hurt you at times
age structure of deer in your area, pressure, cover, deer density numbers all have SO much to do with calls working or not IMO
I personally tend to always CARRY a grunt tube, and or bleat/can call
but seldom use them, I sort of use them as if a BIG buck is out of range and ONLY going to get farther away(AKA going wrong way) and I don't think he will be back any time soon
THEN when I can SEE the buck I will try calling as a last ditch effort to get him!
I am NOT a fan of calling blindly
all my yrs of hunting , I have had WAY more encounters with big bucks NOT calling than calling, so thats MY preference
when the stars line up , things can be magical with calling, but from my experience, more times than not, all you do is let smarter deer know some idiot is up a tree with a fake call LOL and they then avoid the area! having doen more harm than good to your spot!
I have hunted whitetail deer in about 15+ states and Canada, and that's my 2 cents!
