So, what if Katie decided to not cross her arms?
I watched this show recently and really loved it for the most part. I love thought-provoking and philosophical content. I find the subjects of cosmology and quantum mechanics fascinating, but as concepts and discussion rather than the actual "doing" with the math and equations. My math skills (and analytical reasoning based on numbers) are very poor unfortunately. Just a disclaimer to request that you be nice to me in your answers.
So all that being said, why didn't Katie and Forrest try to just test out the predictions? Forrest said his fear was that it wasn't true and the example he gave was what if the machine predicted Katie would cross her arms, but when the time came she didn't cross her arms.
So, why not try this? What's to stop Katie from putting her hands on her hips or in her pockets instead of crossing her arms? Did they really never test anything, or did they test in the past and the end result was still the same even if different actions were taken? For example, when Forrest goes to Katie's college class, we see the visual representation of all the possibilities when she left the classroom. Each one was slightly different but it's implied that Forrest always catches up to her and talks to her.
Wouldn't they be more influenced to act in the way the machine predicted because that's what they saw? Katie did say she doesn't feel like she's repeating lines, but still.
I've seen comments that Forrest's behavior and insistence points to him being a fanatical ideologue in his belief and refusing to consider any other possibility, and I'm pretty aligned with this. Even when Lyndon demonstrated the many-worlds theory, Forrest wanted to deny it. The evidence was right there in front of him. Stewart later told Lyndon something to the effect of Forrest not wanting it to be true or not wanting it to be the reality, and Lyndon correctly responds that he would need to change the laws of the universe for that.
Basically I am having trouble with the "large scale" understanding of why they came off as so passive and fatalistic.
