Predictive Analytics Concerns

I read Tom Davenport article that he wrote to Harvard Ph.D. students and graduates concerning predictive analytics.  It is a very good article.  The article explores some of the questions that students asked in the Analytics Academy class he teaches each May.   

Since I am not a Harvard student or graduate, I did not give any feedback.  However, the questions are really good and I do have a concern.    

My concern about Predictive Analytics is that if you can predict the outcome of what will happen in a situation, then how hard is it to change the situation so the outcome predicted is correct?  So then we are talking about manipulation. I am afraid everything will come down to manipulation.  That is not good. So, how can we avoid it?
