Instantaneous Personal Magnetism will change how one acts and that changes how other people respond. That's the idea of that Paraliminal.
I agree that you cannot change another persons belief that's why I recommended the Instantaneous Personal Magnetism Paraliminal because one needs to change themselves they cannot change other peoples believe.
I think you misunderstood the reason why I suggested using Instantaneous Personal Magnetism and not the Belief one. And I did identify that decision2change was trying to change other peoples beliefs. That you cannot do but you can change how they react to you and how you perceive their reaction by changing yourself.
