Shapes and proportions of hands reveal one of four basic personality types. INTUITIVE or PRACTICAL qualities dominate when fingers are shorter than palms. Intuitive types with their long palms and short fingers take chances when they’re inspired and are impatient and easily bored when they’re not. Practical types with square palms and short fingers are logical, methodical, pragmatic, and make decisions based on objective reality. When fingers are longer than palms, THINKING or FEELING qualities dominate. Thinking types with square palms and long fingers are communicators who have to work hard to stay focused, disciplined, and structured and not spread themselves too thin. Feeling types with long palms and long fingers have to build trust in order to be comfortable with others. Large hands enjoy detail and organization. Small hands detest detail, are conceptual, and love big ideas. Small-handed folk need to delegate the detail work. Reading hands is like a Meyers Briggs personality test incarnate.
Speaking of details, every detail needs to be examined in the context of the whole and all other details at the same time. The danger in interpreting details out of context is in substituting one form of pre-determinism for another by reducing individuality to cookbook formulas. Most palmistry books do that. Every detail has meaning (even rings, scars, warts and birthmarks). Until you have determined the basic hand type, all details are superficial. The meaning of any detail can change depending on the question asked and the character of the individual. No matter what our circumstances, we still have plenty of free will to exercise our thinking, feelings, and actions. We cannot alter the past, but we can change our present and influence our futures.
