Mate, this is going to look like I’m trying to **** on you because it seems like I always have something to say, but I’m honestly not lol. But there’s a ton of red flags in that study. First, peertechz is a predatory publication that is not a legitimate scientific journal. You can read a
little more here, but yeah it can be hard to tell. Second that article is very very dodgy. I'm not sure how used you are to reading academic articles, but I will just point out some red flags that jump out:
1-Bad English and poor referencing
2-The way the article is written is highly irregular and does not follow the format or rules of research papers. There's no info about how participants were recruited or how the data was analysed or what statistical tests were done in order to imply a correlation ( I don't believe there was any done to be honest). Basically this "study" has not run the statistical tests necessary to compare two populations (tattoo vs no tattoo) and has not provided the results of any tests. It talks about "significant results" but doesn't actually provide any p values. Honestly if I presented this in uni they'd tell me to go back to year 1.
3-Papers usually talk about the various limitations and caveats that there may be in any given study, his only limitation is "The main limitations of the research is one: the PICI-1 is not yet standardised psychometric instruments but are proposed, despite the excellent results obtained ". Using a non-standardised test to diagnose is silly, first off. But upon further research, I realised he is actually the author of the instrument too (actually PICI stands for Perrotta Integrative Clinical Interview, Perrota being himself) and it was published in the same dodgy journal. Of which as it turns out, he is Editor-In-Chief.
4- Of the 49 references in the article, 38 are articles he himself has authored, and some of them are not relevant at all. I suspect this is so it appears that they have been cited more often than they actually have.
5- Our boy Giulio is extremely prolific, he has published 97 books, papers, and psychometric instruments since 2019 about honestly all sorts of things. I don't need to explain why that is impossible and just crazy. This includes articles about clinical evidence in alien abductions and demonic possession, a psychopathological profile of the biblical god Yahwe, every psychopathology under the sun, cuckolding, epilepsy, spleen trauma, and his own protocol to improve your gut flora.
6-He claims to be working as a PhD student in a university but the department he is in doesn't actually exist as far as I can tell.
Honestly I'm losing my mind. I just wanted to mention a few pointers about how to tell if a paper is likely to be legit and I've been down this rabbit hole for I kid you not, 2 hours. I'm so sorry. I don't even know if this guy is real.
We need a thread for Giulio
