The word "thinking" used here is the problem. You are using it in the context of rationalizing particular factors and making a decision seeing this happening in the brain and labelling thinking. You are also taking the preemptive action spoken about as the same brain enacting measures for self preservation and equating the two.When you see a big guy coming at you with a big knife and run is your preemptive action a result of your thinking "this doesn't look good/looks dangerous?
Yes, they both occur in the brain but the processes are different. Being startled by a loud noise suddenly happening near isn't you thinking "i must move" as it is an automatic and natural response initiated from the brain.
