Fixed Attitude: I hate Broccoli!
Manipulation: You wouldn't eat broccoli if you really loved me.
A more subtle version might be:
Fixed Attitude: I love broccoli!
Manipulation: I am obsessed with broccoli and behave badly (or well) in order to get my way.
Think of "Manipulation" (or its original label Psychology) as expressed through behavior, while Fixed Attitude as expressed through attitude or mindset.
In your Santa's elves example, you make the mistake of saying (story-wise) that you want it to go from Fixed Attitude to Manipulation, when a story would not explore both of those domains within the same context. I think it is better to look at the same subject matter and express it as two DIFFERENT story possibilities:
FIXED ATTITUDE: Santa, "My elves make the best toys in the world."
MANIPULATION: Santa, "I try to be the best Santa I can be so I can be a role model for my elves and inspire them to be the best toymakers they can be."
