ELI5: How come when im expecting something to happen (like a jump scare) I get spooked/jumped more than I would not expecting it?

If you're expecting it, your fight or flight response is already readied and your body and mind are focused and tense. However, in a situation where you're not expecting anything, there's a delay between when the stimulus is registered and the body reacts. There's less built up tension and prepared response with a random spook than if you're already expecting something to happen.
