I dont think it lessens your chance of seeing does, but i guess it depends on the deer, some bucks dont wanna fight and they'll get scared and trot off, same with some does. I have rattled does in though, it was passed shooting light and i was walking back to the house with a full moon and in a field i walk across i saw a deer so i rattled just to see what would happen and i just kept walking as if i was a four legged animal, maybe like a cow and the deer i saw ran towards me untill about 20 yards away and it turned out to be a doe, or maybe a spike i couldnt tell that well because of the light situation.

So i guess i think i would rattle becvause you have that chance of haveing a nice deer come in to the calling, but you also have the chance of scaring that deer away.
