Why You Overthink Every Decision: Perfectionism and the Fear of Getting It Wrong

Perfectionism can turn ordinary choices into exhausting attempts to find the one “right” decision.

Some people make a decision and move on. Others make a decision, reconsider it, research it again, ask someone else what they think, imagine three different ways it could go wrong, and then wonder whether the fact that they are still uncertain means they have chosen badly.

If that sounds familiar, the problem may not be that you are bad at making decisions. In fact, many people who struggle with indecision are thoughtful, conscientious, responsible, and very good at anticipating consequences. The difficulty is that when perfectionism gets involved, making a decision can start to feel less like choosing between two reasonable options and more like trying to identify the one choice you will never regret.

That is an impossible standard, but it can be a surprisingly hard one to let go of.

Perfectionism often gets described as simply having high standards, but in practice it tends to be much more complicated than that. For many people, it involves a strong fear of making mistakes, disappointing others, overlooking something important, or discovering afterward that they “should have known better.” When that same pattern shows up in decision-making, even ordinary choices can become exhausting.

You may find yourself overthinking decisions about work, relationships, purchases, parenting, social situations, or even small things that objectively do not matter very much. The specific decision changes, but the internal process is often remarkably similar: you want to make sure you are getting it right.

Why perfectionists struggle with decision-making

Most decisions involve some degree of uncertainty. You can gather information, weigh the pros and cons, and make a thoughtful choice, but you usually cannot know in advance exactly how things will turn out.

For someone with perfectionistic tendencies, that gap between “I have enough information to decide” and “I know for certain this is the right decision” can be deeply uncomfortable.

This is one reason perfectionism and overthinking so often travel together. Instead of using thought to help you make a choice, you may begin using thought to try to eliminate uncertainty altogether.

You might keep researching because you are afraid you missed something. You may ask several people what they would do, then feel even more confused when they give you different answers. You might imagine every possible outcome and try to determine which one you could live with. Sometimes you finally make the decision, only to start second-guessing it almost immediately.

At that point, the goal is no longer simply to make a reasonable decision. The goal has quietly become to feel completely certain about it.

And that is where people tend to get stuck.

This is also closely related to the way perfectionism can fuel anxiety. When mistakes feel unusually consequential, the mind naturally spends more time trying to prevent them. The problem is that the more seriously you treat the possibility of making the “wrong” choice, the more threatening uncertainty starts to feel.

The fear of making the wrong decision

One of the most common themes I see in perfectionistic thinking is the belief that there must be a correct answer if you think hard enough.

Sometimes there is. If you are comparing interest rates or checking whether a medication interacts with another medication, gathering more information may genuinely lead to a clearer answer.

But many of the decisions that people agonize over are not that kind of decision.

Should you take the new job or stay where you are? Should you move? Should you end a relationship? Should you speak up about something that bothered you? Should you take a risk or choose the safer option?

There may be good reasons on both sides. Neither choice may be perfect. You may gain something and lose something either way.

For a perfectionistic person, this can be incredibly frustrating because there is no amount of analysis that can turn an uncertain life decision into a guaranteed outcome.

You are eventually forced to do something perfectionism hates: make the best decision you can with the information you have, while accepting that you cannot know everything.

When research turns into reassurance

Research is not inherently a problem. Neither is asking for advice. Both can be useful parts of thoughtful decision-making.

The difference is what happens after you already have enough information.

If you have compared the realistic options, identified what matters to you, and gathered the information you need, but you still feel compelled to keep looking, you may no longer be problem-solving. You may be trying to reassure yourself.

This can look productive because you are technically doing something. You are reading, comparing, asking questions, making lists, or thinking through scenarios. But psychologically, the purpose has changed. Instead of helping you arrive at a decision, the process is helping you temporarily manage the anxiety of not knowing.

Unfortunately, reassurance tends to have a short shelf life.

You find one answer that makes you feel better, and then another question appears. You read ten positive reviews, but one negative review suddenly feels more important than the other ten. Someone tells you they think you are making the right choice, but later you remember that another person disagreed.

The search continues because what you are really looking for is not more information. You are looking for a feeling of certainty.

This same pattern often shows up in people who struggle with high-functioning anxiety and chronic overthinking. From the outside, they may look highly capable and careful. Internally, however, they can spend an enormous amount of mental energy trying to avoid mistakes or prevent future regret.

Why second-guessing does not stop after you choose

For some people, making the decision does not actually end the decision-making process.

You choose the job and then wonder whether the other one would have been better. You buy something and immediately check the alternative again. You send the email and reread it several times. You decide not to attend something, then spend the evening wondering whether you should have gone.

This kind of second-guessing can create the impression that you must not really trust yourself.

Sometimes that is part of it. But often, what is happening is simpler: your brain is treating the continued presence of uncertainty as evidence that the decision is still unresolved.

It is not.

You can feel uncertain and still have made a perfectly reasonable decision.

You can wonder what would have happened if you had chosen differently and still move forward.

You can dislike part of an outcome without concluding that you made a mistake.

One of the most important shifts in working with perfectionism is learning that discomfort after a decision does not automatically mean the decision was wrong.

This same process can also show up as rumination after social interactions. If you tend to analyze what you said, how you came across, or whether someone interpreted you the wrong way, you may relate to why your mind keeps replaying conversations.

Perfectionists are often afraid of future regret

Sometimes the real fear is not even the outcome itself. It is the way you imagine you will treat yourself if the outcome is disappointing.

If you already know that your inner response will be, “I should have known better,” “I cannot believe I missed that,” or “Why didn’t I think this through more carefully?” it makes sense that you would feel enormous pressure before making a decision.

You are not only trying to protect yourself from a bad outcome. You are trying to protect yourself from future self-blame.

That is one reason simply telling yourself to “stop overthinking” rarely works. The overthinking is serving a function. It is an attempt to prevent criticism, regret, embarrassment, or the feeling that you failed.

This is similar to what happens when perfectionism leads to procrastination. Avoiding a decision or putting something off can reduce anxiety temporarily because you do not yet have to face the possibility of getting it wrong. Unfortunately, the relief does not last, and the decision often becomes even more emotionally loaded over time.

Why asking everyone else can make decisions harder

When you do not trust your own judgment, it is tempting to outsource the decision.

You ask your partner. Then your friend. Then another friend. Maybe you search online to see what strangers would do. Each opinion gives you a little more information, but it also introduces another perspective you now have to account for.

Eventually, instead of deciding between two options, you are also trying to decide whose opinion you should trust.

Seeking outside input can absolutely be helpful, especially when someone has expertise or knows you well. The problem is when you begin to feel unable to move forward without external validation.

Over time, that can weaken self-trust rather than strengthen it.

The more often you teach yourself, “I need someone else to confirm that this is okay,” the harder it becomes to tolerate making a decision that another person might not make.

Confidence is not the same thing as certainty

A lot of people assume that confident decision-makers simply feel more certain.

Sometimes they do. But often, confidence has much less to do with knowing what will happen and much more to do with trusting that you will be able to handle whatever happens next.

There is a meaningful difference between saying, “I know this is definitely the right decision,” and saying, “I have thought this through, this choice makes sense to me, and I can deal with the outcome.”

The second version is much more realistic.

Self-trust does not mean believing that you will never make the wrong call. Nobody can promise themselves that.

It means knowing that if you eventually discover you would have preferred a different choice, you can adjust, learn something, or make another decision.

That is much sturdier than certainty.

For people who appear very competent but still chronically doubt themselves, this dynamic can extend well beyond decision-making. It often overlaps with constant internal pressure, self-criticism, and the sense that you always need to anticipate the next problem before it happens.

How to stop overthinking decisions

If you tend to get stuck in decision paralysis, the goal is not to become impulsive or stop thinking things through. Thoughtfulness is a strength. The work is learning to notice when thoughtful reflection has crossed over into repetitive analysis that is no longer helping.

One useful question is: What information am I still waiting for?

If there is a concrete answer, such as waiting for a salary offer or getting a medical test result, then waiting may make sense.

If the answer is something closer to “I just want to feel more sure,” that tells you something important.

It can also help to decide in advance how much research a decision deserves. A major financial decision may warrant substantial thought. Choosing between two restaurants probably does not. Perfectionism often treats both as if there is an optimal answer that needs to be identified.

Another helpful question is: What matters most to me here?

Perfectionism tends to focus on avoiding the wrong outcome. Values-based decision-making shifts the question toward what you actually want to move toward.

Maybe the safest job is not the one that gives you the most room to grow. Maybe the apartment with the larger kitchen is not in the neighborhood you actually want to live in. Maybe keeping everyone else happy is not the same thing as making a choice that fits your own needs.

There is rarely one decision that maximizes every possible value at the same time.

Part of making decisions is accepting tradeoffs.

Practice making low-stakes decisions without reopening them

If you have spent years second-guessing yourself, building self-trust usually happens through practice rather than insight alone.

Start with small decisions.

Choose what you want for dinner without reading thirty reviews. Pick the shirt. Send the email after reviewing it once or twice rather than repeatedly. Make the weekend plan and resist reopening it simply because another option occurred to you later.

Then notice the urge to revisit the decision without automatically obeying it.

This is not about proving that your original choice was perfect. It is about learning that you can tolerate the ordinary uncertainty that comes with choosing.

Over time, your brain gets more experience with something important: a decision does not have to feel completely certain in order to be finished.

Therapy can help when perfectionism and overthinking take over

When chronic indecision is driven by perfectionism, the work is usually deeper than learning how to make a better pros-and-cons list.

In therapy, we may look at why being wrong feels so threatening, where your standards came from, how much responsibility you tend to take for preventing negative outcomes, and what happens internally when you cannot be certain.

For some people, these patterns are closely connected to self-criticism. For others, they are tied to anxiety, fear of disappointing people, family expectations, or an identity built around being competent and responsible.

The goal is not to make you care less about your choices. It is to help you make thoughtful decisions without spending hours trying to guarantee an outcome that cannot be guaranteed.

If you recognize yourself in this pattern, you may also relate to my articles on the connection between perfectionism and anxiety, why perfectionists procrastinate, why your mind replays conversations, and high-functioning anxiety.

I work with adults who struggle with perfectionism, chronic overthinking, self-doubt, and anxiety. Therapy can help you build greater confidence in your own judgment while becoming more comfortable with the uncertainty that is part of making real-life decisions.

Frequently Asked Questions

• Why do I overthink every decision?

  People often overthink decisions because they are trying to reduce uncertainty, avoid regret, or prevent themselves from making a mistake. Perfectionism can intensify this pattern by creating the expectation that there is one “right” choice and that you should be able to identify it if you think hard enough.

• Is indecisiveness a sign of perfectionism?

  It can be. Not everyone who struggles with indecision is perfectionistic, but perfectionism often contributes to difficulty making decisions because mistakes can feel unusually important. You may spend excessive time researching, comparing options, asking for reassurance, or second-guessing yourself because you are afraid of choosing incorrectly.

• What is analysis paralysis?

  Analysis paralysis describes getting so caught up in evaluating options that it becomes difficult to make a decision. Instead of helping you reach a conclusion, continued analysis creates more possibilities, more uncertainty, and more reasons to keep thinking.

• Why am I so afraid of making the wrong decision?

  Fear of making the wrong decision is often connected to anxiety, perfectionism, fear of regret, low self-trust, or harsh self-criticism. If you believe you should always make the best possible choice, normal uncertainty can start to feel like a sign that you have not thought enough.

• Why do I keep second-guessing myself after making a decision?

  Second-guessing often happens because your brain continues searching for certainty even after the decision has been made. New doubts do not necessarily mean you chose incorrectly. They may simply reflect discomfort with uncertainty or a longstanding habit of mentally reviewing your choices.

• How do I know when I have thought about a decision enough?

  A useful question is whether additional thinking is producing genuinely new information. If you are repeating the same arguments, seeking reassurance, or reviewing the same options without learning anything new, more thinking is unlikely to make the decision clearer.

• How can I stop overthinking and make decisions faster?

  Try identifying the most important factors, setting limits on research, noticing when you are seeking certainty rather than information, and practicing making lower-stakes decisions without reopening them. The goal is not to make perfect decisions faster. It is to become more comfortable making reasonable decisions without complete certainty.

• Can therapy help with indecision and overthinking?

  Yes. Therapy can help you understand what makes decisions feel so high-stakes, address perfectionistic thinking and anxiety, reduce reassurance-seeking and rumination, and build more confidence in your own judgment. For many people, the goal is not simply faster decision-making but greater self-trust.
