Well it depends on what instinct. I will guess you mean in a dangerous situation for a horse. If there is a frightening event a domesticated horse will usually gallop to their home, or most likely, the barn. That is very dangerous, especially if the barn has caught fire. But for a wild horse their first instinct is usually to run away.
to run that is a horses first instinct
Fight or Flee
its first instinct is usually to flee from that person but depends how scared it is if its not that scared it will just bite

The horse may spook for many reasons. There may be shadows you don't notice, litter blowing by, a new or missing object, impaired vision or just high spirits. To correct the spooking you must first identify what is causing the spooking in the first place and then attempt to get the horse desensitized to it through a repeated approach and retreat method until the horse is no longer afraid of what's causing the problem.

Horses are prey animals, there instincts are flight and then fight. So they first will flee from the situation and then if that doesnt work they fight.
Horses have two main instincts when they are faced with a situation that they find frightening. One is fright. This when the horse runs away from the threat, by either spooking or simply getting away from the thing scaring it. The other is fight. This is when the horse stays and tackles the thing it is frightened of head on. It often bucks or rears when it sees what is scaring it.
