The terms come from the French Revolution: in the National Assembly of 1789, supporters of the revolution sat to the president's left, defenders of monarchy and tradition to his right. The seating chart became shorthand for a real divide — between those who want society deliberately changed toward greater equality, and those who want its inherited institutions preserved.
Leaning left typically means favoring economic redistribution, a stronger social safety net, and social change: the sense that existing hierarchies are unjust and that collective action — usually through government — should correct them.
Leaning right typically means favoring free markets, lower taxes, and cultural continuity: the sense that inherited institutions carry accumulated wisdom, and that change should be gradual and earned rather than engineered.
Both descriptions are honest — and both are incomplete, because they bundle together questions that don't have to move together.
