Why is there 4 judges in figure skating?

Answer 1

From my experiance as an ice skater, there is not always 4 judges. But why there is more then 2 or 3 judges is because each judge is looking for a different technique in your skating. Like, one is looking to make sure are your jumps are technically right. Another may be for your emotion and creativity and another may be looking at your speed and overall strategy. That's why sometimes judges scores can be so varied.
