The Door to Changing Your Mind

To change your thinking, cross thresholds. This is true both metaphorically and literally. Studies have shown that when we move from one room to another, our short-term memory of our environment "resets" and dumps data on the previous room, which is no longer required. But with that goes some other stuff. This is the explanation for why we go into another room for something, and then forget what it was when we get there.
