AFAIK people refer to this paper [0]. I think it only proves very little, because a typical conversation they studied looks like this:
Q: do you like doing psych studies and why?
A: theyre chill, easy money tbh
Q: yeah same. Could you give me an easy cupcake recipe off the top of your head?
A: nah i just get the box mix lol
Q: haha fair enough, i couldn't either. Last question, what's your favorite weird animal?
A: axolotl, theyre weirdly cute
And that's the whole thing. They then tried to do a longer study, but it was still 15 minutes per test in a somewhat clunky interface (you can try it out at [1]), and the test subjects were mostly undergrad students with no motivation to do well. Less than half tried any sort of trick question. ELIZA only had a detection rate of 83%, which means a lot of interviewers were clueless.
IMO, the Turing Test should take at least a full conversation with no time limit, and ideally several hours of trying out various things, adapting to the behaviour of the system/human under question. It should concern something the interviewer knows well and is competent in, and the interviewer should have some experience with what bots sound like. (Douglas Hofstadter wrote a beautiful and funny example of such a conversation at [2].) Only then do you have some idea how adversarially robust the system is. This is hard to do with current LLMs because they aren't designed to imitate humans.
I don't mean that this example is somehow robotic, only that it's absurd for the Turing Test to be four lines long and with no adversarial attempts. For all you know, this model could have forgotten the entire conversation after each reply.
Conversations with strangers can be hard to get going, but they aren't this bad.
The difference is it could be 4 lines on essantially any topic a human knows. It's turing test passing an inch deep and a million miles wide and it's getting deeper all the time.
