What makes something objectively right or wrong?

Nothing really makes something objectively right or wrong in the way we might want - morality seems to come from a mix of human values, cultural agreements, and what actually reduces suffering or promotes wellbeing. You can build consistent frameworks for ethics (like "actions that maximize flourishing are good"), but you'll always run into people who disagree on the fundamentals because we don't all share the same ultimate goals or beliefs. Most philosophers accept that while we can have strong reasons for calling things right or wrong, true objectivity - like you'd have with math or physics - doesn't apply the same way to moral questions.

The tricky part is that people often confuse "widely agreed upon" with "objectively true" - just because most societies converge on certain moral rules (don't murder, keep promises) doesn't mean those rules exist independently of human minds the way gravity does. We're really good at building solid ethical systems based on reducing harm and respecting autonomy, but that's still a human construction, not a law of the universe.

Don't expect to find objectivity by looking outward - you'll just find more humans arguing. What gets interesting is realizing that even when we can't prove something is objectively right, our actual choices still have real consequences for real people, and that might matter more than whether we can ground morality in some cosmic rulebook. The question isn't really "what makes it objective" but maybe "what makes it binding on me anyway," and that's where personal conviction and community actually do the heavy lifting.
