My Bay's ears... :~D
I learned from my old grey Arab stallion, whose ears always pointed in the direction of his next idea.
Don't they though. Scotty's left ear would signal a refusal as he approached a jump. If you didn't stear around the jump when his left ear cocked back, you were going to go over the jump by yourself. But to Scotty's credit, something was usually not right. Jumps spaced to close, pace too fast or slow, girth too loose/tight or "busy hands". If Scotty was comfortable, his ears pointed straight over the rails.
