Handwriting and Personality

So I was watching Sherlock Holmes: A Game of Shadows when I saw this scene where Sherlock Holmes deduces from Professor Moriarty's handwriting that he has genius-level intellect and is basically a psychopath using his knowledge of graphology, or the psychological analysis of handwriting. This made me curious about whether this was legitimate, so I started to research it. I came across this PDF: https://www.ijarcsse.com/docs/papers/Volume_5/1_January2015/V5I1-0296.pdf, and I wanted to see what this theory said about my fellow ENTPs. According to this, I am intelligent, spontaneous, unstable, and stubborn, so it seems pretty accurate for me. What does this theory say about you?
