JK Rowling isn’t just the author of the Harry Potter saga: she’s also the undeniable queen of Twitter – particularly when it comes to her social media takedowns.

From Theresa May to Piers Morgan, the author has used her digital version of the Quick Quotes Quill to call out a plethora of public figures on their actions. Unsurprisingly, President Donald Trump is often in Rowling’s sights – but she recently upped the ante and used his own signature to troll him.

Oh yes.

It all kicked off when someone shared a photo of Trump’s abnormally large signature on Twitter.

“Why?” they captioned it. “Why is his signature so big? Why, god, why?”

Rowling, thankfully, had the answer, offering up a graphologist’s reasoning for the POTUS’ exaggerated autograph.

Sharing a screenshot of an article, originally posted on Handwriting & Graphology, Rowling admitted: “I didn’t believe in graphology until about three minutes ago.”

So what changed her mind? 

Well, the article Rowling has cited suggests those who have overly large writing are arrogant megalomaniacs who possess tyrannical qualities.

“Large writing means that we are before an arrogant person, conceited, haughty, who needs to exhibit compliments and recognitions, tyrant tendencies, exhibitionist and phony personality that may become megalomaniac with a lack of critical sense,” it reads.

“The insecurity and inferiority complex and lack of self-esteem may be compensated with large writing. [And], when the signature is larger than the text, this reflects pride, consciousness of self-value and […] shows the individual has more ambitions than real possibilities.”

It’s a subtle drag, but it certainly gets Rowling’s point across.

While there is no evidence to suggest graphology is a legitimate science, the write-up does match Harvard psychiatrist Lance Dodes’ analysis of Trump’s personality to a tee.

“The best diagnosis for Trump is that he is a malignant narcissist,” he previously shared with Salon. 

“It contains the narcissistic part, which is no big deal alone – lots of people are narcissistic – but the malignant part is the sociopathy dimension.

“These terms suggest that Trump is a very primitive man. He is also a man who has a fundamental, deep psychological defect. It is expressed in his inability to empathize with others and his lack of genuine loyalty to anyone.

“You will notice that Trump wants everyone to be loyal to him, but he is loyal to nobody.”
