Indoctrination has symptoms, of which shepard displays none. It makes you paranoid, you get headaches, feel subtle whispers that can't be ignored. And when we do see attempts at straight up indoctrination, i.e, the Illusive man controlling you, there is even a visual effect on screen that bioware made to show when you were being controlled, at no other time does the visual effect appear, nor does he exhibit any symptom of indoctrination, and I feel the most compelling argument against IT is that if they did control shepard, they wouldn't risk giving him the choice of using the catalyst, but force him to either pick control or synthesis, or simply do nothing and have him betray his allies, seriously, when you control somebody's mind you don't give him a gun, point it at yourself, and see if he'll shoot.
