The rules, in plain language

How it works

Normally a graphologist looks at handwriting and describes a personality. Here it runs the other way. You describe yourself in everyday words. Each word nudges one or more of 20 personality scales. Those scales are combined into 33 handwriting features with weights taken from the classic interpretations. For example, slant mostly comes from head vs. heart, with some from reserved vs. outgoing. The features then drive a handwriting engine that writes every letter as a moving pen.

Most features have several causes, and most traits affect several features. That is how graphology itself works: no single sign means anything on its own. Only the whole picture, the gestalt, does. Two people who both call themselves “outgoing” can still get quite different handwriting if the rest of their description differs.

The compare page uses the same weights in reverse. It measures your real writing and finds the personality that best explains what it sees.

How the pen moves

Graphology also reads how the writing was made: its speed, rhythm and pressure, and the order of the strokes. The engine doesn’t just draw letter shapes. It simulates a pen:

• School-model stroke order. Ovals in a, o, d, g are written counter-clockwise from the top right. The upstroke into an oval climbs its left side, and the oval then retraces it. Loops in l, b, h go up on the right and come down on the left.
• Joins between letters come from the connective form. Garland writers swing up through cups, arcade writers hug the downstroke and arch over, angular writers zig-zag and thread writers flatten out.
• Speed follows curvature. Real hands slow down in tight curves and speed up on straight strokes, roughly following the “two-thirds power law” of motor control. The animation does the same. Overall speed comes from the writing speed feature.
• Delayed strokes. Quick writers dot the i and cross the t after finishing the word, and often cross a double t with one stroke. Slow, careful writers stop and do it at once, which leaves a break in the word.
• Pressure is heavier on downstrokes. Fast writers start and end strokes thin and pointed. Slow, heavy writers leave blunt, club-shaped endings. Light pressure also gives paler ink, as with a real ballpoint.
• Natural variation. No one writes the same letter twice. Irregular and moody profiles vary more in size, slant, spacing and baseline. “Another sample” on the main page shows the same person writing again.
• Legibility. Fast, private writers let the ends of long words trail off into thread-like strokes.

Is graphology real?

Honestly: not as a way to read personality. When graphologists are tested under controlled conditions, without the content of the text to give clues, their personality judgements are no better than chance, and they don’t predict job performance. Several reviews and meta-analyses have concluded this, for example Neter & Ben-Shakhar (1989) and Dean (1992).

Handwriting does carry real information of other kinds. Forensic document examiners can tell writers apart. Handwriting also changes with age, fatigue, illness and medication, for example the shrinking “micrographia” of Parkinson’s disease.

So enjoy this as what it is: a playful, faithful rendering of a historical rulebook, not a psychological test. The compare page shows how well the rulebook happens to fit you.
