In animals some things are definitely hardwired. I had a pet rabbit and made the mistake of watching a nature documentary about snakes when she was in the room. The mere sound of a rattle snake on TV caused the rabbit to stamp a few times, spray urine, and run away to her hutch (skidding on the floor as the left).

I'm sure humans have similar instincts. For example, the tendency of young kids to avoid plants until they are shown that they are edible - possibly leading to the general preference of artificial foods over anything that might be found in a garden. [1]

I've also noticed that toddlers don't gravitate towards knives the same way they do everything else. I certainly wouldn't rely on this behaviour, but I've noticed it in my own children and others.
