I don't think it's a decision at all. Even if I am hoping (in my movie example), I never really believe that anything is going to change. I do not decide to hope, I just do. I don't think I have any control over it. Someone else (with a more pessimistic world view) might not hope for the better. This agrees with a deterministic world, where previous influences made me an optimistic person, making me feel hope.Sparklehorse, your comments about hope reinforce my assumption that hope is a decision to choose to believe differently about what is to come, particularly in the face of evidence suggesting a likely unfavourable outcome.
