The number of times a batsman will be unsure of whether he's nicked something will be miniscule, and thus for a batsman who always walks when he nicks one this will not be a problem.If batsmen walk, when Umpires aren't sure (doubt is 'not out' btw), then when that batsman does not walk, the Umpire will naturally start to think "He must not be out". And that is a very dangerous situation. Obviously, too, the only time when walking comes into the picture (almost invariably) is when there's some obvious doubt.
Say Gilchrist is known for walking when he knows he's out. In the World Cup final, he gets a fine edge, West Indies appeal, and he decides not to walk. The Umpire, being a human being, will doubt whether he's out, on some level.
The Umpire has to be allowed to make the decision. Walking is an avoidable influence on the Umpire.
Selective walking is of course even more unfair play than non-walking.
But 100%-honest walking will reduce the number of incorrect decisions, not increase it.
