Three parts of the thumb
- Top phalange (tip): willpower and determination.
- Middle phalange: logic and reasoning.
- Base (mount of Venus): love, vitality and passion.
Thumb length
- Long thumb (reaching above the middle of the index finger's lower section): strong will, leadership and independence.
- Short thumb: more emotional, easily influenced, guided by the heart.
Thumb shape
- Thick, broad tip: forceful, determined, sometimes stubborn.
- Slim, refined tip: tactful and diplomatic.
- Waisted middle section: tact and good judgement.
A balanced thumb, where will and logic are of similar length, shows someone who thinks before acting.
