The real Turing test requires an expert doing the test, not just some random easily impressed person.

The ELIZA-style bots work very well on the later kind, as the bot is just repeating your own text back at you with some grammatical remixing, e.g. you say "I am afraid of horses", bot says "Why do you say you are afraid of horses?". You can have very long conversation with yourself that way, as the bot contributes nothing to the discussion. It just provides enough plausible English to keep you talking. Meanwhile when you have an expert (or really just any person with a little bit of a clue) test ELIZA, the bot falls completely apart within just three lines of dialog. The bot is incredible basic and really can't do anything by itself, it completely depends on the user to provide all the content of the conversation.
