I judged a little schooling show for horses yesterday. It is hard to be fair sitting on the other side of the run. I wanted to reward the cute, the sad, the hard trier. I didn't really want to use the rider I overheard making nasty comments about her competition. Judging the classes I was judging yesterday is a lot more subjective than agility - more like rally maybe - and sometimes more like figuring skating. But even so I made every effort to put everything out of my mind except what I could actually see in front of me. The subjective bit popped up when I had two equal performances and had to split them somehow. Then I made every effort to share the love around ;)
Fair standards, clarity and consistency that's what the best judges embrace and uphold that means a "bad" judge might just be the best of judges. Embrace them. Learn from them. And use what they teach you the next time you compete!
