That linked study doesn't particularly resemble Turing's test, though? The authors asked an LLM some questions (like personality tests, or econ games), then reduced the responses to low-dimensional aggregates (like into "Big Five" personality traits), and compared those aggregates against human responses to the same questions. They found those aggregates to be indistinguishable, but that aggregation throws away almost all the information a typical human interrogator would use to judge.

Turing's interrogator also gets to ask whatever questions they think will most effectively distinguish human from machine. Everything those authors asked must appear in the training set countless times (and also corresponds closely to likely RLHF targets), making it a particularly unhelpful choice.
