After playing the game Eliza, I came across a study from this year.
They found strikingly interesting results (particularly the first one), quoting from their abstract:
‘In a large sample (N = 830), we showed that a) participants could rarely tell the difference between responses written by ChatGPT and responses written by a therapist, b) the responses written by ChatGPT were generally rated higher in key psychotherapy principles, and c) the language patterns between ChatGPT and therapists were different.’
My first reflex is to check the data and analysis. So, I quickly went to the method section, here is a screenshot:

Here is the second given link above. Below, you can see what is available on the OSF (Open Science Framework).

All locked, I have seen nothing, no data. As a published author, I can understand how overwhelming this process is. What I do not understand is: how is this published without open access while giving that promise? There are so many professionals involved in the process… Anyhow, I could not see any email to notify the authors so that they can add the data / or make it public.
I hope they will rectify that soon. Otherwise, it is discouraging to read studies..
Cheers,
