Horses are 'flighty' because they are prey animals, in other words, they are on the menu. Their number one defense is speed, and when in doubt, they run. They can be trained to compensate for this, search 'sacking out'.
Yes. Horses are herd animals, they find safety in the herd. Being separated from the herd can cause a horse to be very nervous and flighty.

A wild or feral horse will be weary of anything new, they tend to be very flighty and will run at first chance. However if they deem whatever is nearby to be safe they may move in to investigate it. If cornered a wild / feral horse can and will become aggressive and violent.
