You've been paying a man to warn you if there are tigers on the main street. Every day for the last 10 years he's been telling you there are no tigers on the main street and you've taken the main street or he's told you there are tigers there and you've taken the side street. Today he said that there was a tiger on the main street but you took it anyway and didn't see the tiger. Has his trustworthiness collapsed or was he always scamming you?
