You're a horse that cannot reason and you're instincts are self-preservation. What keeps your self-preservation in check is the built-in fear. Fear makes you run from danger. Fear is what keeps you alive. If you don't understand something you fear it even more.

Now knowing all that, imagine you're the horse and you're standing at the edge of the river. You won't cross it because you think there's danger in it somehow. On top of that, someone is on your back, pissed off and kicking you in the ribs because you won't go forward.

Not only are you scared of the water, but now you're getting kicked in the ribs and feeling punished. You want to be obedient and go forward but your instinct is too powerful and tells you not to.

It would be like telling a scared child who just saw a scary movie that he had to sleep in his own damn room.

But what if Gene had understood his horse was scared? What if he helped his horse deal with his fear.

How would he do this?

When Gene and his horse approached the water he could have spoke to his horse in a pleasant, soothing manner. When the horse was getting scared Gene should have recognized it as fear and not as disobedience.

He could have petted his horse to reassure him all is okay. He could have talked to his horse in a pleasant manner. He could have let his horse sniff the water and check it out on his own.

Instead, the horse was now confused, scared, feeling punished, less trusting of his rider, and who knows what else.

But if Gene would've recognized the fear in his horse then he could have helped his horse overcome it. Gene lost the awesome opportunity to gain a significant amount of the horse's confidence and friendship in that river scene. Too bad too. That's a beautiful paint horse.
