Why is arachnophobia so prevalent although only about 5% of spiders species are lethal to humans?
Your freeze flight or fight instinct doesn't distinguish the thing you're seeing consciously. Spiders are a combination of fear triggers: long and angular legs, dark colours, darting and erratic movement. Your [amygdala](_URL_0_) noticed those little things and went "this is fast, I can't predict…
The Short Answer
Your freeze flight or fight instinct doesn't distinguish the thing you're seeing consciously. Spiders are a combination of fear triggers: long and angular legs, dark colours, darting and erratic movement. Your [amygdala](_URL_0_) noticed those little things and went "this is fast, I can't predict it, I don't know what it is, get ready." The amygdala also plays a role in associating emotion with memory and fear gets a prominent attachment, so people can feel unease just looking at a picture of a spider. That and a lot of kids inherit their parent's fears. We learn through social interaction how to behave and this helps with survival of the species. My mother is deathly afraid of spiders and despite rationally knowing they're (mostly) harmless, I still panic a little. Spiders are also fuckin' everywhere. all. the. time.
