Your signature is a representation of your public self-image, or how you act in public and around other people, or your social persona. What you think of yourself in public, what you’d like others to think of you, and what you think others think of you are all included in the term public self-image. It’s similar to having your own stamp. It reflects how you feel about yourself, how you’d like people to feel about you, and how you think they feel about you. A signature reveals a person’s personality by displaying essential personal characteristics; it also reveals the writer’s inferiority problem, whether he is actively striving to compensate for it or whether he feels himself too superior to do so.
Everyone does not act the same way in public (in crowds, at school, or at work) as they do in private (in relationships, at home with family and friends). Some people, for example, are OK in small groups but get insecure when they are in a public setting, such as a party. Then there are those who only come alive and sparkle when they are invited to a party. They may have a gregarious personality, but they are insecure and/or dull when it comes to one-on-one interactions.
What does your signature mean in terms of your public image? Why is it analyzed in a different way than the rest of the data? We infer that your signature represents your public self-image based on a straightforward psychological deduction. When you write sentences and paragraphs, you are communicating feelings and ideas. Your conscious attention is drawn to these feelings and ideas, as well as how to communicate them. When it comes to signing, however, you’re conveying something very different: you’re leaving your name, your self, and your public identify on the page.
Graphologists will be able to tell whether you are not the same person in public as you are in private based on your writing. How? By contrasting your signature (your public persona) with the rest of your work (your real, or private, self-image). When someone says, “You know, my signature doesn’t look anything like the rest of my handwriting,” what they’re really saying is that his public behavior isn’t representative of his private behavior; what you see isn’t always what you get.
It’s best to incorporate the writer’s natural signature when assessing a sample of handwriting. There may be a clear contrast between the writer’s personality and character, who may not be who he appears to be; this may manifest itself in a signature that is more forceful than the specimen’s body. When a person’s disposition is modest or meek, but his or her character is stronger than first appears, this will be reflected in a humble signature, even if the rest of the writing reveals hints of strength.
We have a person whose façade is guarded and distant, even though underneath he may be kind and responsive, where the text flows to the right yet the signature is written at a vertical angle. He may have been obliged to adopt a calm, dignified demeanor due to circumstances.
When the body of the writing is vertical and the signature flows to the right, you’ll notice a reserved person who gives off the idea of being friendly and spontaneous, but who doesn’t easily warm up or become close with others. Although a person’s job may need him to have an outgoing attitude in order to win others over, there will always be some barrier between him and others. This person is an introvert with an outgoing personality.

If the signature has the same size, style, slant, pressure, and spacing as the rest of the text, then the person operates the same manner in public as in private. When in public, such a person does not put on airs or switch personalities. You get exactly what you see.

When a person’s signature is larger than the rest of the text, we know we’re dealing with someone who thinks he’s significant. Because he did it and said it, he believes what he does or says is significant. He is the leader, and when he exercises his power over others, it is felt. Your signature should be the same size as, or somewhat larger than, the rest of your writing if you have a healthy sense of self-confidence in public. This characteristic denotes a good sense of self-assurance in public.

When the signature is ineffective, possibly smaller than the rest of the writing, we judge the personality negatively. Such people tend to minimize their own importance, and the specimen’s physique will show evidence of masochism and self-abnegation. There have been times where such retired persons have made an impression on the outside world through their profession.

An illegible signature indicates that the author does not want the public to know too much about him. He could be hiding something, or he could be unconcerned about whether or not others understand him. We may be confident that the writer has an engaged and perhaps unique personality if the signature is so complicated and involved that it is illegible, and we wonder what kind of person he is. Many people, on the other hand, sign their names so frequently throughout the day that they lack the patience to write them legibly. That is something we must consider. As a result, if you believe a signature was illegible due to the writer’s haste, that’s all it means, and it’s not necessarily noncommunication.
Underscoring means underlining. If present in the signature, the underscore is a sign of assertiveness in and of itself. It also tells us whether we’re dealing with a strong and magnetic personality, a one-of-a-kind individual, or someone who is unusually extroverted. It is an attention-getting device that is commonly found in the handwriting of people who are in the public eye or who aspire to be in the public eye. A simple underline in your signature denotes healthy self-confidence and self-reaffirmation. However, if there are too many lines, the opposite feeling is compensated for. Someone who uses a lot of underscores in her signature is someone who is unsure of her public importance and is attempting to make herself appear more important.

Though it is not possible to make a definitive analysis based solely on a signature, the signature contains a significant amount of information about the character. To draw firm conclusions solely based on the signature, more perspicacity and experience are required.
