It's a methodology that fails to be part of science since it can't be always give 100% consistent scientific result. Is it bad? Not really, since graphology always spot on with the base traits. Although you'll need to have many years of experience to dig deeper in analysis.
Have you ever wondered why your handwriting is clear and neat at start of exam and very messy at end. It happens because your mind is running fast at last moment and was calm at start. Another example is introvert, extrovert. Einstein was an introvert and his handwriting was small. Check your own handwriting if it's medium then you are an Ambivert, small then introvert, large then extrovert
Psychology and graphology only fails to be 100% consistent. But most of the time, it can easily reach 90% end result. So yeah it's not pseudoscience, but a working methodology that's just slightly off to be always 100% consistent.
