The right hand's historical privilege is so deeply embedded in language, gesture, and social practice that it is almost impossible to discuss neutrally. Oaths are sworn on it. Deals are sealed with it. Divine favour, in most iconographic traditions, descends from the right hand of God. The left has been associated, across cultures from ancient Rome to medieval Christianity to several Asian traditions, with the sinister, the inauspicious, and the impure.
Palmistry inherited this bias and formalised it. The right hand became the hand of manifest life — action, achievement, the future. The left became the hand of what you were given at birth — potential, character, the inheritance you did nothing to earn.
The irony is that the left hand is sometimes specifically identified as the hand money flows into — the receiving hand. In this interpretation, the left hand is where luck arrives, even if the right hand is where it is deployed. Whether your left or right hand is luckier therefore depends on whether you are asking about causing good fortune or receiving it.
