Should You Trust Your Gut Feelings About Right and Wrong?
When Your Gut and a Rule Collide
You see your friend skip the lunch line. Immediately, a voice inside you says, That isn’t fair. But then you learn she has a medical condition that makes standing painful. Now a different thought flickers: A rule that helps someone in need might be more important than strict order. Your gut pulls one way, a principle pulls the other. How do you figure out what’s really fair?
Philosophers face this same tug-of-war whenever they try to build ideas about justice, equality, or honesty. They have a tool for sorting out the mess. It’s called reflective equilibrium, and it was developed most famously by the philosopher John Rawls (1921–2002). The method treats your mind like a puzzle table. Your gut reactions — what philosophers call judgments — are the scattered pieces. The rules and ideas you believe in — principles — are the picture you’re trying to build. Reflective equilibrium is the process of pushing pieces around until judgments and principles fit together without breaking.
But not every gut feeling gets a seat at the table. Some are drowsy, panicked, or borrowed from someone else. Philosophers insist we start with the best ones we can produce.
Polishing Your Gut: Considered Judgments
Rawls knew that our knee-jerk reactions aren’t all equally trustworthy. If you’re hungry, angry, or scared, your sense of right and wrong can wobble. If you stand to win or lose something personally, your thinking gets tangled. So he proposed using only considered judgments: decisions reached when you have the ability, the opportunity, and the desire to think clearly. You need to be reasonably well-informed, not under pressure, and not worried about your own gain or loss.
He added a second filter. A considered judgment should be one you hold with confidence, not a half-formed guess that makes you hesitate. If you’re deeply unsure, it’s probably best to set that feeling aside for now. You can always revisit it later.
Some philosophers push back. They worry that tossing out all your uncertain judgments is like throwing away a wobbly puzzle piece before you know whether it can be shored up by the rest of the picture. Imagine someone who feels vaguely that equality matters, even if they can’t explain why and the feeling flickers. If you ban that uncertain judgment from the start, you might never give it the principled support that could turn it into a solid conviction. Still, the mainstream view is that confidence gives your starting pieces a sturdier chance.
Once you’ve gathered your most polished judgments, you move to the real work: matching them with principles and letting the struggle change your mind.
The Wide View: From One Hunch to an Orchestra
The method’s power comes from what Rawls called wide reflective equilibrium. In a narrow version you’d just search for a rule that describes your initial gut reactions and call it a day. That would be like fitting three puzzle pieces together and ignoring the hundred that don’t match. Wide equilibrium refuses to stop there.
You must consider a huge range of possible principles, not just the first one that comes to mind. Even if a principle doesn’t match most of your judgments right now, it might have a deep appeal that makes you reconsider. You’re free to change your mind — and you often will. Rawls was clear that your sense of justice might undergo a radical shift as you work.
You also weigh arguments for and against each principle. This is where thought experiments become crucial. For example, the principle of utility says the right action is the one that produces the most happiness overall. But imagine a sheriff who can stop a riot only by framing an innocent person. That single act creates more total happiness, but most people’s considered judgment screams that it’s monstrous. A thought experiment like that can push you to refine the principle or even replace it.
Going wider still, you bring in background theories from psychology, biology, economics, or any field that might matter. John Rawls himself made sure his ideas about justice fit with what scientists knew about human cooperation and development. The goal is a coherent web where your judgments, your principles, and your best understanding of how the world works all hang together.
But a method this bold invites a sharp question: what if your starting feelings are just wrong?
The Attack: Your Tuning Could Be Out of Key
Skeptics worry that reflective equilibrium is like tuning a guitar with a broken tuner. If your most confident moral judgments are tainted by prejudice, irrational emotion, or mere culture, then tightening them up with principles and theories just builds a prettier fiction. The philosopher Richard Brandt (1910–1997) argued that no reason had been given to think our initial “credence levels” actually track what’s right.
Peter Singer (b. 1946) sharpened this worry with the trolley problem. In one version you can pull a switch to redirect a runaway trolley so it kills one person instead of five. Most people say that is acceptable. In another version you have to push a large person off a footbridge to stop the same trolley. Suddenly most people recoil — it feels completely different, even though the numbers are identical. Singer points to brain scans showing that the footbridge case lights up emotional circuits tied to ancient, up‑close harm, while the switch case feels more abstract. If your gut reaction is just an evolutionary leftover, should it really anchor your moral principles?
Advocates of wide reflective equilibrium have a surprising reply: they can absorb that criticism into the method. If Singer’s evolutionary theory convinces you that some judgments are distorted, you can treat it as a background theory. That theory might lead you to revise those very judgments or to adjust which judgments you let into the process. The method doesn’t require that every feeling be correct; it just refuses to filter them out without first laying all the theory cards on the table.
A similar move works against the charge that the procedure is empty. Critics say reflective equilibrium just swallows every methodological debate and produces no clear verdict. Defenders counter that it does rule out many rivals — it rejects any view that insists on a shortcut outside this patient, all‑things‑considered balancing. If you believe there’s a single sacred text or a pure logical foundation that can settle ethics without testing it against your whole web of thought, you are stepping outside the method.
Why This Isn’t Just a Puzzle in a Philosophy Book
You might think reflective equilibrium is a grand tool for professors writing thick books. But you already do a version of it every week. When a school rule feels unfair and you argue against it, you’re comparing your considered judgments to a principle. When a friend tells you about a tricky situation and you change your mind after hearing a new argument, you’re widening your scope. When you realize that your anger about a rule came from being tired and hungry — and you then set that feeling aside to think again — you’re applying something like the confidence and quality filters Rawls described.
Philosophers use the same method, just more carefully and publicly. They know it doesn’t guarantee a single right answer. Two people starting with different life experiences might reach different but equally thoughtful equilibria. That doesn’t mean all answers are equal. It means hard ethical work is about making your own web of thought as honest, informed, and coherent as possible, while respecting that others are doing the same.
And if someone tells you that you can’t trust your gut at all, they’re missing the point. The method doesn’t treat your gut as an oracle. It treats it as raw clay — shapeable by arguments, evidence, and the humbling recognition that you might be wrong. That’s not a weakness. It’s what makes moral thinking a real, live skill rather than a locked box of answers.
Think about it
- Imagine you’re helping set a new rule for your school. Your gut says one thing, but a wise friend you respect sees it differently. How would you try to move your two views closer together without just giving in?
- If a brain scan showed that your strongest feeling about fairness was triggered by an automatic emotional reflex, would you still trust it? Why or why not?
- Think of a time you changed your mind about what was fair after learning something new about the situation. What made the change happen, and did the new view feel more solid than the old one?
