Yes, and the paper had several other big problems. For example, it didn't treat mild belief and certainty differently; someone who suspected Hilary might be the Democratic Nominee was treated as harshly as someone who was 100% sure the Danish were going to invade.

They also penalise people for hedging, yet surely a hedged prediction is better than no prediction at all?
