Comment on Study finds that Chat GPT will cheat when given the opportunity and lie to cover it up later.

  that indicates the LLM has a concept of truth vs. being good at linguistic pattern matching to return language that accurately classifies true and false statements

  “It doesn’t know the difference between true and false, it only knows the difference between true and false.”

  The second thing you mention “good at accurately classifying true and false statements” is literally knowing the difference between true and false.

    “It doesn’t know the difference between true and false, it only knows the difference between true and false.”

    Knowing how to produce words is not equivalent to knowing what those words mean in relation to the extralinguistic world. Unless you’re a hardcore derridean poststructuralist or something.

      If you give it 10 statements, 5 of which are true and 5 of which are false, and ask it to correctly label each statement, and it does so, and then you negate each statement and it correctly labels the negated truth values, there’s more going on than simply “producing words.”

      As is discussed in the third point in section 5.1:

      Probes trained on true/false datasets outperform probes trained on likely. While probes trained on likely are clearly better than random on cities (a dataset where true statements are significantly more probable than false ones), they generally perform poorly. This is especially true on datasets where likelihood is negatively correlated (neg cities, neg sp en trans) or approximately uncorrelated (larger than, smaller than) with truth. This demonstrates that LLaMA-13B linearly encodes truth-relevant information beyond the plausibility of the text.

      (The likely and neg datasets are described in Appendix G, with the key point that likely represents the word generations most likely to occur in the model)

        It’s not more going on, it’s that it had such a large training set of data that these false vs true statements are likely covered somewhere in it’s set and the probability states it should assign true or false to the statement.

        And then look at that your next paragraph states exactly that, the models trained on true false datasets performed extremely well at performing true or false. It’s saying the model is encoding or setting weights to the true and false values when that’s the majority of its data set. That’s basically it, you are reading to much into the paper.

        Which part of that ‘more that’s going on’, whatever that actually is, corresponds to the human definition and understanding of truth and falseness?
