There is no central authority in palmistry. No licensing board. No standard textbook that all readers agree on. Instead, there are dozens of traditions: Indian, Chinese, Western, Cheiro, Benham, modern psychological palmistry, folk palmistry, and more.
Each tradition has its own rules. One counts any vertical line as a child. Another counts only deep, clear lines. One reads a heart line fork as balance. Another reads it as a love triangle. One sees a broken fate line as career change. Another sees it as an inheritance.
Add to this the fact that line visibility changes with skin condition, hand position, lighting, and the reader's eyesight. The result is a practice where disagreement is not an accident. It is a feature.
