Why Does Overthinking Make Us Doubt Ourselves?

You make a decision and feel reasonably comfortable with it. Then you think about it again. You imagine another possibility, notice something you may have missed, question your original reasoning, and eventually become less certain than you were at the beginning. How can more thinking sometimes create less confidence?

Thinking carefully is useful. We need reflection to make decisions, learn from mistakes, anticipate consequences, and reconsider assumptions that may be wrong. Changing our minds after discovering new information can be a sign of good judgment rather than weakness.

But thinking does not always continue producing useful information simply because we continue doing it.

There are moments when reflection begins to circle around the same uncertainties. We revisit a conversation without learning anything new from it. We evaluate a decision from ten slightly different angles. We imagine what other people might think, then question our interpretation of what they might think. Eventually, the original question becomes surrounded by so many hypothetical possibilities that certainty feels impossible.

This is where overthinking can affect confidence. Not necessarily because the thoughts are false, and not because self-doubt is always harmful, but because repeatedly reopening a question can make it difficult to know when we have enough information to move forward.

The important distinction is therefore not between thinking and not thinking. It is between thinking that helps us understand something and thinking that repeatedly returns us to the same uncertainty.

When Does Thinking Become Overthinking?

There is no exact number of minutes after which ordinary reflection becomes overthinking. The difference often has more to do with what the thinking is accomplishing.

Imagine preparing for an important presentation. You review your slides and notice that one explanation is confusing. You rewrite it. Then you rehearse and realize that another section is too long, so you shorten it. Your thinking is producing identifiable changes.

Now imagine that the presentation is finished. You have checked the information, practiced several times, and corrected the problems you found. Yet you continue asking: What if everyone thinks this is obvious? What if I sound nervous? What if someone asks a question I can’t answer? What if the presentation isn’t as good as I think it is?

Those questions are not impossible scenarios. Some of them could happen. The problem is that repeatedly asking them may no longer produce an action that meaningfully improves your preparation.

A useful question is therefore: “Is this thought giving me new information or a reasonable action to take?”

If the answer is yes, continuing to think may be useful. If the answer is repeatedly no, you may have moved from problem-solving into repetition.

Why Can Repetition Make a Thought Feel More Convincing?

A thought does not become true merely because it appears frequently. Yet familiarity can influence how convincing something feels.

Suppose you make a small mistake during a meeting and later think, “I probably looked unprepared.” You replay the moment while driving home. You remember it again before sleeping. The next morning, you imagine how your colleagues may have interpreted it.

After enough repetition, you may stop experiencing “I probably looked unprepared” as one interpretation among several possibilities. It begins to feel like a description of what definitely happened.

But what new evidence appeared between the first thought and the twentieth?

Perhaps none.

This is an important question because repetition can create familiarity without creating evidence. The fact that a thought keeps returning tells us that our attention keeps returning to it. It does not, by itself, tell us whether the conclusion is accurate.

That does not mean we should automatically replace every negative thought with a positive one. “Everyone thought I was brilliant” would be just as unsupported if we had no evidence for it.

A more grounded alternative might be: “I made one mistake during the meeting. I don’t actually know how everyone interpreted it.”

The goal is not forced optimism. It is greater accuracy.

Why Does Overthinking Often Search for Certainty?

Many situations do not provide complete certainty. We cannot know exactly how another person interpreted our words. We cannot guarantee that a decision will produce the outcome we want. We cannot predict every question we might be asked or every problem that could appear.

When uncertainty feels uncomfortable, more thinking can seem like a way to remove it.

Consider choosing between two opportunities. You compare the advantages and disadvantages, gather the information available, and speak with people who can answer practical questions. Eventually, however, there may still be uncertainty because neither option comes with a preview of the future.

At that point, another three hours of thinking may not reveal the objectively correct choice. There may not be one.

But if we believe that enough analysis should eventually eliminate uncertainty, we can interpret the remaining uncertainty as evidence that we have not thought hard enough. So we return to the decision again.

Confidence in situations like these does not necessarily mean becoming completely certain. Sometimes it means recognizing that we have gathered enough information to make a reasonable decision even though some uncertainty remains.

Can Self-Doubt Ever Be Useful?

Self-doubt is often described as something we need to defeat, but a complete absence of doubt would not necessarily improve our judgment. Questioning ourselves can be valuable.

If you are about to make an important financial decision, checking whether you have overlooked something is sensible. If someone tells you that your behavior hurt them, immediately assuming your own perspective must be correct may prevent you from listening. If you are working on something unfamiliar, recognizing the limits of your knowledge can encourage you to ask questions or seek additional information.

The problem is not that doubt exists. The problem arises when doubt becomes difficult to satisfy.

Healthy doubt can respond to evidence. You check the numbers, correct an error, learn what you were missing, and continue.

Repetitive self-doubt can move the standard every time you meet it. You prepare, but wonder whether you prepared enough. Someone reassures you, but you wonder whether they were only being polite. You succeed, but decide the task must have been easy. You receive a compliment, but search for a reason it may not count.

If every piece of evidence that could support confidence is immediately disqualified, the problem may no longer be a lack of evidence.

How Can Overthinking Affect Confidence Over Time?

Confidence is not simply a feeling we either possess or lack. Part of it develops through experience: making decisions, attempting things, responding to mistakes, learning what we can handle, and discovering that uncertainty does not always prevent us from functioning.

Overthinking can interfere with that process when it repeatedly delays action.

Imagine wanting to contribute an idea during a meeting. You think of what you want to say, then wonder whether it is useful. You revise it mentally. Someone else begins speaking, so you wait. You reconsider whether your point is still relevant. By the time there is another opportunity, you decide it is probably better not to say anything.

Nothing necessarily went wrong. Nobody rejected the idea. But you also did not get the experience of expressing it and seeing what happened.

If this pattern repeats, confidence may have fewer opportunities to develop through actual feedback. Instead, predictions begin replacing experiences: They probably wouldn’t find it useful. I might explain it badly. Someone else probably knows more.

This can create a difficult cycle. Doubt reduces action, reduced action produces less real-world information, and the lack of new information leaves more room for doubt.

Are You Evaluating Yourself or Predicting Other People’s Thoughts?

Overthinking often includes imagined evaluations from other people. They probably thought I sounded foolish. She must think I’m difficult. He probably noticed that I was nervous. They must be wondering why I said that.

Sometimes other people do judge us negatively. It would be unrealistic to pretend otherwise. But unless they communicate what they think or we have other meaningful evidence, our prediction remains a prediction.

One way to notice this is to examine the language of the thought. Words such as probably, must, surely, and I bet they think can sometimes reveal that we have moved from observable events into interpretation.

For example:

“I paused for several seconds while answering the question” describes something observable.

“Everyone realized I didn’t know what I was talking about” interprets what other people thought about that pause.

The interpretation may be correct, partly correct, or completely wrong. The important point is knowing which part we actually observed.

Separating those two layers can prevent an imagined judgment from quietly becoming evidence against our confidence.

Why Doesn’t “Just Stop Overthinking” Usually Solve the Problem?

Telling ourselves to stop thinking about something can sound simple, but it does not tell us what to do when the thought returns. And trying to force a thought away can sometimes give it even more importance because we begin monitoring whether we are still thinking about it.

A more practical response may be to change our relationship with the question.

Instead of “How do I stop thinking about this?”, ask “Is there anything left for me to do with this thought?”

If you made a mistake, perhaps there is something to correct. If information is missing, perhaps you can obtain it. If a decision still needs to be made, perhaps you can identify the criteria that matter most.

But if nothing new can reasonably be checked, corrected, decided, or acted upon, continuing the mental review may not bring you closer to an answer.

Sometimes the next step is not another thought. It is allowing an unresolved amount of uncertainty to remain while you continue with what comes next.

How Can You Separate Facts From Interpretations?

One reason overthinking can become convincing is that facts and interpretations often appear together in our minds. After a while, we may stop noticing where one ends and the other begins.

Suppose you send someone an important message and they do not reply for several hours. The observable fact is simple: they have not replied yet. But the mind can quickly add explanations: They’re annoyed with me. I said too much. They don’t know how to respond. They are deliberately ignoring me.

Any of those explanations might eventually turn out to be correct. But at that moment, they are possibilities rather than established facts. The person could also be working, sleeping, traveling, distracted, thinking about their response, or dealing with something completely unrelated to you.

A useful exercise is to divide what you are thinking into three categories: what you know, what you are interpreting, and what you are predicting.

What I know: They haven’t replied since I sent the message this morning.

What I’m interpreting: I think the message may have bothered them.

What I’m predicting: I’m worried this will affect our relationship.

This exercise does not tell you that your interpretation is wrong. Instead, it gives each thought the level of certainty it actually deserves.

That small distinction can be particularly useful when self-confidence is involved. “I made a mistake” and “I’m terrible at this” may feel closely connected, but they are not the same statement. The first can describe an event. The second is a much broader conclusion about your ability.

What Evidence Are You Using Against Yourself?

When self-doubt becomes repetitive, we may become surprisingly selective about what counts as evidence. Negative information receives considerable attention while positive information is quickly explained away.

Imagine receiving feedback on a project. Four comments are positive and one identifies something that needs improvement. Later that evening, which comment are you replaying?

Perhaps it is the critical one.

There is nothing wrong with paying attention to useful criticism. In fact, the critical comment may contain the most actionable information. The problem begins if you use that one observation to erase everything else: They said several things went well, but they were probably just being nice. The criticism is what they really think.

Notice what happened. Positive evidence was subjected to suspicion, while negative evidence was accepted immediately.

You can test this pattern by asking: “What evidence would I accept if it supported the opposite conclusion?”

If no success is sufficient, no compliment is believable, and no positive outcome counts because there is always another explanation for it, your standard may have become impossible to satisfy.

Balanced thinking does not mean collecting only evidence that makes you feel good. It means applying roughly the same level of scrutiny to evidence that supports you and evidence that challenges you.

Are You Asking a Question That Can Actually Be Answered?

Some overthinking continues because the question itself has no definite answer available to us.

“Did everyone like me?”

“Did I make the perfect decision?”

“What if I regret this five years from now?”

“Can I guarantee that this won’t fail?”

“What did they really think about me?”

We can spend enormous amounts of time trying to solve questions like these without noticing that the information required to answer them may not exist.

Changing the question can sometimes make reflection more useful. Instead of “Did everyone like my presentation?”, ask, “What feedback did I actually receive, and what would I improve next time?” Instead of “How do I know I won’t regret this decision?”, ask, “Given what I know today, what reasons support each option?”

The new question may not remove uncertainty, but it gives you something you can realistically examine.

Why Can Replaying Conversations Damage Confidence?

Conversation replay is a familiar form of overthinking. A discussion ends, but mentally it continues. We reconsider our wording, imagine better responses, analyze the other person’s expression, and wonder whether a particular sentence sounded strange.

Reviewing a conversation can sometimes be useful. Perhaps you realize that you interrupted someone repeatedly or that an explanation was unclear. You can remember that information and respond differently next time.

But replay becomes less useful when each review creates another hypothetical problem. Maybe my joke sounded rude. Maybe they noticed I was nervous. Maybe I talked too much. Maybe I didn’t talk enough.

The difficulty is that memory is not a video recording that lets us return to the event and obtain perfect certainty about what everyone thought. We are reviewing the interaction through our current concerns and interpretations.

If there is a specific issue you can reasonably clarify or repair, that gives the reflection a direction. If there is not, it may help to acknowledge: “I am reviewing this conversation again, but I do not have new information about how the other person interpreted it.”

That does not force the thought to disappear. It simply prevents repetition from being mistaken for investigation.

What Can You Write Down When Your Thoughts Keep Circling?

Writing can sometimes help because it moves a vague mental loop into a form that can be examined. Instead of repeatedly thinking “I messed everything up,” you have to decide what you actually mean by that sentence.

You might begin with five questions:

“What happened?”

“What am I telling myself that it means?”

“Which parts do I know, and which parts am I assuming?”

“Is there something useful I can do now?”

“If there is nothing more I can do, what uncertainty am I trying to eliminate by continuing to think?”

Suppose the thought is “I’m not good enough for this job.” Writing may reveal that the thought appeared after one difficult assignment. You can then become more specific: “I struggled with this particular task because I didn’t understand part of the process.”

That statement creates different possibilities. Perhaps you need more practice, clearer instructions, feedback, or additional knowledge. Those are problems that can potentially be addressed. “I’m not good enough” offers far less information about what to do next.

If you prefer guided questions rather than beginning with a blank page, you can explore the Mibosma Free Tools. Choose a prompt that helps you examine the thought rather than using journaling to repeat the same conclusion for another page.

Can Journaling Become Another Form of Overthinking?

Yes. Writing is not automatically reflective simply because thoughts are placed on paper. We can reproduce the same mental loop in a journal, sometimes in considerably greater detail.

Imagine writing five pages about why someone has not replied to your message. You describe every possible interpretation, reread the previous conversation, analyze their punctuation, compare their response time with earlier messages, and finish without having acquired any new information.

You have written extensively, but the central uncertainty remains exactly where it began.

This does not mean the writing was necessarily useless. Perhaps you needed a private place to express frustration or anxiety. But if your goal was clarity, it is worth noticing whether the journal is helping you distinguish information or simply giving the loop more space.

A useful stopping question is: “Have I learned anything new in the last paragraph?”

If the answer is no, you might summarize what you currently know in one or two sentences and close the journal. You can return when new information exists or when you have a different question to explore.

What Happens When We Wait for Confidence Before Acting?

It is natural to want confidence before taking a risk. We imagine that once we feel sufficiently certain, speaking up, applying, publishing, deciding, or trying something unfamiliar will become easier.

Sometimes additional preparation genuinely does increase confidence. If you have never given a presentation before, practicing it is useful. If you are applying for a position that requires particular knowledge, learning more can improve both competence and confidence.

But there are situations in which confidence cannot be completed entirely in advance because part of the information comes from doing the thing itself.

You cannot know exactly how you will handle every question until you participate in the meeting. You cannot know whether people will respond to your work until you share it. You cannot discover what an unfamiliar responsibility feels like without beginning to experience it.

If action is postponed until all self-doubt disappears, the threshold can keep moving.

A different standard might be: “Am I prepared enough to take the next reasonable step?”

The next step does not have to be enormous. It could mean asking one question, sharing one idea, submitting one application, requesting feedback, or trying something once rather than deciding in advance whether you are capable of doing it forever.

Can Action Give Us Information That Thinking Cannot?

Thinking produces possibilities. Action sometimes produces evidence.

If you believe, “I’ll embarrass myself if I speak during the meeting,” you can analyze that prediction repeatedly without learning exactly what will happen. Speaking once provides new information. Perhaps the idea is well received. Perhaps someone disagrees. Perhaps the moment is completely ordinary and nobody reacts strongly at all.

Even an imperfect outcome can be informative. If your explanation is unclear and someone asks you to clarify, you learn something specific that can improve the next attempt. That is different from remaining silent and allowing an imagined failure to become the only available version of events.

This does not mean every fear should be confronted impulsively or that every risk is worth taking. Context matters. Preparation matters. Consequences matter.

But when a reasonable action is available and the main obstacle is repeated uncertainty, doing something small can sometimes answer questions that another hour of internal debate cannot.

How Do You Know When You Have Thought About Something Enough?

There is rarely a perfect moment when the mind announces that analysis is complete. It can therefore help to create practical stopping criteria.

For a decision, you might identify the information you genuinely need before choosing. Once you have it, additional thinking should have a specific reason rather than continuing indefinitely.

For a past event, ask whether there is anything to learn, clarify, apologize for, or do differently. If you have identified the lesson and there is no further action available, replaying the event may not add much.

For a future worry, ask whether there is a reasonable preparation you can make. If there is, make it. If there is not, recognize that the remaining problem may be uncertainty rather than insufficient planning.

The goal is not to become someone who never reconsiders anything. Good judgment includes revision. The goal is to notice when reconsideration has stopped changing the answer and started weakening your ability to trust any answer at all.

Is All Repetitive Thinking Unhelpful?

No. Repetition alone is not enough to decide whether a thought process is useful or harmful. We sometimes need to return to the same subject several times before we understand it, make a difficult decision, learn from an experience, or prepare for something important.

Imagine receiving detailed criticism on a piece of work. You may think about it that evening, return to it the following day, compare it with your original approach, and eventually decide what you want to change. The subject has occupied your mind repeatedly, but the thinking has produced greater understanding and a practical response.

Now imagine returning repeatedly to the same criticism while asking, “Why am I never good enough? Why do I always get things wrong? What if this proves I shouldn’t be doing this at all?” The subject may be similar, but the process is different. Instead of becoming more specific, the thinking becomes broader and more self-critical.

This distinction matters because the goal should not be to eliminate every thought that repeats. A better question is whether returning to the thought is helping you understand, decide, prepare, learn, or act — or whether you repeatedly arrive at the same distressing conclusion without gaining anything new.

What Does Research Say About Repetitive Thinking?

Research on repetitive thinking supports a more nuanced view than the idea that thinking about something repeatedly is always harmful. A review published in Perspectives on Psychological Science examined both constructive and unconstructive forms of repetitive thought and found that the consequences can differ depending on factors such as the content of the thinking, the situation in which it occurs, and whether the person is thinking in a broad, abstract way or in a more concrete and specific way.

This distinction fits an important idea throughout this article: repetition itself is not necessarily the problem. Thinking repeatedly about how to prepare for an upcoming challenge can be different from repeatedly asking what a mistake says about your worth. Reviewing a problem to identify the next action can be different from returning to a question that has no new information available.

If you would like to explore the research directly, you can read Constructive and Unconstructive Repetitive Thought through PubMed Central.

Research also uses terms such as rumination and repetitive negative thinking for particular patterns of repetitive thought. These concepts have more specific meanings in psychological research than the everyday word overthinking. For that reason, it is better not to assume that every period of thinking too much is clinical rumination. Everyday overthinking can describe many experiences, from repeatedly reconsidering a decision to replaying an awkward conversation.

Why Can Concrete Questions Be More Useful Than Global Ones?

Notice the difference between “Why am I so bad at this?” and “What part of this task did I struggle with?”

The first question asks for a judgment about the person. The second asks for information about a particular experience.

If you struggled during a presentation, “Why am I terrible at speaking?” can lead almost anywhere. You may begin reviewing old embarrassing moments, comparing yourself with confident speakers, or imagining future failures.

But “What part of the presentation was hardest?” creates something more specific. Perhaps you knew the material but rushed because you were nervous. Perhaps one section was poorly organized. Maybe answering unexpected questions was difficult.

Each possibility suggests a different response. You might rehearse more slowly, restructure the difficult section, or practice answering questions. The broad judgment “I’m terrible at speaking” does not provide the same direction.

When overthinking becomes self-critical, moving from global judgments toward specific observations can therefore be useful. Instead of asking what one experience proves about you, ask what actually happened and what, if anything, you want to do differently.

What If the Thought Keeps Returning After You Have Answered It?

Sometimes we reach a reasonable conclusion and the question still returns.

You decide that your message was respectful, but an hour later you wonder whether it sounded rude. You check it again. It still seems reasonable. Later, the doubt returns: Maybe I’m missing something.

At this point, repeatedly producing the same answer may not create greater certainty. Instead, each new review can teach us that whenever doubt appears, the entire question must be reopened.

One alternative is to acknowledge both the conclusion and the uncertainty: “I reviewed the message and I think it was reasonable. I cannot know exactly how the other person will interpret it.”

That sentence does not provide perfect reassurance. It recognizes the limit of what you can know.

This can be difficult because uncertainty often feels unfinished. But not every unfinished feeling represents an unfinished problem.

Can Confidence Include the Possibility of Being Wrong?

Confidence is sometimes imagined as certainty: I know I am right. I know I can do this. I know this decision will work.

But that version of confidence is impossible in many ordinary situations. We make decisions with incomplete information. We attempt things we have never done before. We speak without knowing exactly how others will respond. We sometimes discover later that our judgment was wrong.

A more flexible form of confidence can include those possibilities.

“I think this is the best decision based on what I currently know.”

“I prepared carefully, even though I cannot control the outcome.”

“I may make a mistake, and I can respond if I do.”

“Someone may disagree with me, and that does not automatically mean I should never have spoken.”

This kind of confidence does not require eliminating doubt before acting. It allows us to move while recognizing that our knowledge and abilities have limits.

What If Overthinking Is Affecting Everyday Life?

Occasionally replaying a conversation or reconsidering a decision is a common human experience. But repetitive thinking can become much more difficult when it is persistent, hard to disengage from, or substantially interfering with sleep, concentration, work, relationships, or ordinary activities.

If that is happening regularly, the issue may deserve more than another self-help technique. An appropriate mental-health professional can help explore the particular pattern, what may be maintaining it, and what approaches are suitable for the individual situation.

This distinction is important because an article cannot determine whether someone’s experience is ordinary overthinking, clinically significant rumination or worry, or something else. The same outward description — “I can’t stop thinking about things” — can represent very different experiences.

Seeking support also does not require waiting until thinking becomes unbearable. Significant interference with everyday life can itself be a reasonable reason to discuss what is happening.

What Would Change If You Didn’t Need Perfect Certainty?

Many thought loops are difficult to finish because the standard for finishing them is impossible: complete certainty.

We want to know with certainty that we made the right decision, that nobody misunderstood us, that our work is good enough, that we will not fail, or that we will not regret what we choose.

But most meaningful decisions contain some uncertainty. If we require certainty before moving forward, thinking can continue indefinitely because the missing information belongs to the future, another person’s mind, or circumstances outside our control.

A more practical standard might be sufficient information rather than complete certainty.

Have I considered the most important information available to me?

Is there a specific fact I still need to check?

Is there a reasonable action I can take?

Would another hour of thinking meaningfully change the decision?

If new information appears later, can I adjust?

Sometimes confidence grows not from finally eliminating every doubt, but from discovering that we can make reasonable decisions while some doubt remains.

Final Reflection: Does This Thought Need Another Answer?

The next time you notice yourself returning to the same question, you do not have to immediately force yourself to stop thinking about it. Instead, notice what the thought is asking you to do.

Perhaps there really is something you overlooked. Check it.

Perhaps you made a mistake. Decide whether something can be corrected.

Perhaps you need more information. Identify what information would actually change your decision.

But perhaps you have already examined the situation and the mind is asking for something reality cannot provide: certainty about another person’s thoughts, a guarantee about the future, or proof that you will never make the wrong decision.

In those moments, another round of analysis may not strengthen confidence. It may simply reopen a question you had already answered as well as you reasonably could.

Confidence does not have to mean trusting every thought you have or believing that you will always make the right decision. It can be quieter than that. It can mean evaluating the information available, recognizing what you do not know, making the next reasonable choice, and allowing yourself to adjust if new information appears.

You do not need to eliminate every doubtful thought before moving forward. Sometimes the more important skill is learning which thoughts contain something useful to examine — and which ones are simply asking you to solve the same uncertainty again.
