I know you must be surprised about how come bad handwriting would be a sign of fast brain functioning but that is now a scientific fact as per the claims of Arnold L. Gesell’s research work published as open access status in American Journal of Psychology with this DOI.
This research basically claims that students with very high scores have sloppy/bad hand writing such as doctors but notable thing is that their spellings, sentences, and information is always correct which altogether depicts fast processing of information by brain whereas at the same time, physical muscle movements in hand for writing fast is not as possible compared to brain which processes the data at much higher speed.
This psychological research also confirms that if someone’s hand writing is sloppy or bad then there are super high chances that the IQ level, cognitive ability, or intelligence of that person must be on another level.
Another researcher and professor of Harward University known as Howard Gardner’s also claims the same as per his theory of multiple intelligence that you may have higher IQ with creative/intelligent (fast) mind if your hand writing is bad because psychologically there must be a mismatch between functioning of your brain and hand muscles to write fast with good hand writing.
