Why Can’t I Make Decisions?

You need to make a decision. What should I buy? Which job should I choose? Should I move? Should I stay? Should I say yes? Should I say no?

So you start comparing your options. Then you think about the advantages, the disadvantages, the possible consequences, and what other people might think. You search for more information, ask someone what they would do, change your mind, and then wonder whether your first choice was actually better.

Eventually, you're still sitting there thinking -

“Why can’t I just decide?”

This can happen with major life choices, but it can also happen with surprisingly ordinary decisions. You might spend twenty minutes deciding what to order, days choosing between two phones, or weeks wondering whether you should take an opportunity.

The frustrating part is that you may genuinely want to make a decision. You just don't feel confident enough to choose one option and stop thinking about the others.

That is where psychology becomes useful.

Indecisiveness is not simply “thinking a lot.” Research has linked difficulty making decisions with factors such as intolerance of uncertainty, perfectionistic concerns, regret, and choice overload. Recent experimental research has also found evidence that increasing intolerance of uncertainty can increase indecisiveness in personally relevant decisions.

So before calling yourself indecisive, ask a better question -

“What am I afraid will happen if I choose wrong?”

That question often gets closer to the real issue.

Being Careful Is Not the Same as Being Indecisive

Not every person who takes time to decide has a problem.

Sometimes a decision genuinely deserves careful thought. Choosing a university is different from choosing a restaurant. Buying a house is different from choosing a shirt. Ending a relationship is different from deciding what to watch tonight.

Taking your time can be completely reasonable when the decision is important, complicated, or difficult to reverse.

Indecisiveness becomes more noticeable when thinking no longer improves the decision.

You keep collecting information without feeling closer to a choice. You keep comparing options after you already know enough. You repeatedly ask for reassurance. You choose something and immediately wonder whether another option would have been better.

Careful decision-making

“I need more information because this decision has important consequences.”

Indecisiveness

“I already have enough information, but I still don't feel certain enough to choose.”

That difference matters.

The second situation is often less about information and more about how you experience uncertainty.

1. You May Be Uncomfortable With Uncertainty

Every decision contains uncertainty.

You cannot know exactly what your future job will be like. You cannot guarantee that a relationship will work. You cannot know whether moving to another city will make you happier. You cannot know whether one option will eventually turn out better than another.

That uncertainty is unavoidable.

But some people experience uncertainty as especially uncomfortable.

The mind then starts searching for a level of certainty that the decision simply cannot provide.

Research on intolerance of uncertainty has found a strong relationship between difficulty tolerating uncertainty and indecisiveness. A 2025 preregistered experiment found that increasing intolerance of uncertainty led to greater indecisiveness across personally relevant decisions.

That gives us an important insight -

You may not have trouble making decisions because you don't know enough. You may have trouble because you want to feel certain before deciding.

And certainty often arrives after a decision, not before it.

2. You May Be Afraid of Making the Wrong Choice

Some decisions can feel like they have only two outcomes -

Right decision.

Wrong decision.

So your brain treats choosing like a test.

“What if I choose badly?”

“What if I regret this?”

“What if everyone thinks I made the wrong choice?”

“What if there was a better option?”

Now the decision is no longer simply about choosing.

It becomes a threat to your future self.

This can lead to decision avoidance—delaying, delegating, or abandoning a choice to reduce the emotional risk of being responsible for a negative outcome. Research on decision avoidance suggests that postponing or delegating decisions can help people escape the immediate discomfort and responsibility associated with choosing, even though the unresolved decision may create later costs such as regret.

So delaying a decision can feel safer in the moment.

But the decision hasn't disappeared.

You've simply delayed the discomfort.

3. Perfectionism Can Make Every Choice Feel Too Important

Perfectionism doesn't only affect studying, work, or appearance.

It can affect decisions too.

You may feel that there is a best possible choice and that you should be able to find it.

So instead of asking -

“Which option is good enough for what I need?”

you ask -

“Which option is absolutely the best?”

That changes everything.

Now every tiny difference matters. You compare features, prices, reviews, pros, cons, possible consequences, and future consequences of those consequences.

Suddenly, a relatively simple decision becomes a research project.

Recent research has linked perfectionistic concerns with indecisiveness, uncertainty, and sensitivity about mistakes.

The problem isn't caring about doing well.

The problem is believing that a good decision is not enough.

It has to be the perfect one.

4. You May Be Trying to Avoid Future Regret

Regret is one of the hidden forces behind indecisiveness.

You don't just think -

“Which option do I want?”

You also think -

“Which option will I regret less?”

That changes the decision from choosing what fits you best to trying to protect yourself from future disappointment.

Research on decision-making and regret shows that anticipated regret can influence how people search for and evaluate choices before deciding.

Example

Imagine you are choosing between two jobs.

Job A pays more.

Job B offers better work-life balance.

You may already know that both are reasonable choices.

But your mind asks -

“What if I choose A and later wish I had chosen B?”

Then -

“What if I choose B and regret losing the money?”

Now you're not really choosing between two jobs.

You're trying to choose the option that guarantees no regret.

That option may not exist.

5. Too Many Options Can Make Choosing Harder

More choice sounds good until there is too much of it.

One product becomes twenty. One career option becomes six. One course becomes dozens. One holiday destination becomes hundreds of possibilities.

You begin thinking -

“There might be something better.”

Research on choice overload suggests that having many options can sometimes lead to difficulty deciding, avoidance, and regret, particularly when the complexity of the choice becomes difficult to manage.

This doesn't mean more options always create worse decisions.

It means that more options require more comparison, and comparison can become exhausting.

At some point, searching for another option stops adding useful information and starts adding noise.

6. Decision Fatigue Can Make Your Mind Want to Stop Choosing

Think about how many decisions you make in one ordinary day.

When will I wake up? What should I eat? What should I wear? Should I reply now? Should I finish this task first? Which email should I answer? Should I exercise? What should I buy?

By evening, even a simple decision can feel strangely difficult.

Decision fatigue is a useful term for the strain associated with repeated or demanding decisions, although researchers use the concept in somewhat different ways and continue to study its exact mechanisms.

So sometimes the problem isn't -

“I don't know what to choose.”

It is -

“I've already made too many choices today.”

That distinction can change what you need.

Maybe you need a decision-making system, not more thinking.

7. You May Not Fully Trust Your Own Judgment

There is another layer beneath indecisiveness -

self-trust.

You may repeatedly think -

“What if I can't trust my judgment?”

So you ask other people. You read more reviews. You search for another opinion. You make a choice and then reopen the question.

You look for someone to confirm that you made the right decision.

External advice can help you gather information, but it cannot permanently replace your own judgment.

At some point, every decision requires you to say -

“Based on what I know, this is the choice I'm making.”

If you struggle to do that, the real problem may be less about the available options and more about confidence in your ability to handle the outcome.

Why Indecisiveness Can Become a Cycle

Indecisiveness often follows a predictable pattern -

DECISION APPEARS
↓
UNCERTAINTY
↓
"WHAT IF I CHOOSE WRONG?"
↓
MORE RESEARCH
↓
MORE OPTIONS
↓
MORE COMPARISON
↓
MORE DOUBT
↓
DELAY THE DECISION
↓
TEMPORARY RELIEF
↓
DECISION STILL EXISTS
↓
MORE WORRY

Notice something important.

Avoiding the decision can feel good temporarily.

The moment you postpone it, the pressure drops.

That short-term relief can make avoidance tempting the next time you're faced with a difficult choice.

Research on decision avoidance supports the idea that postponing or delegating decisions can reduce the immediate burden of choosing while creating other costs, such as unresolved decisions and regret.

So the goal isn't simply -

“Make decisions faster.”

It is -

“Learn to tolerate the discomfort that comes with making a decision.”

How to Make Decisions Without Overthinking Everything

You don't need to become impulsive.

You need a better process.

Step 1 - Decide How Important the Decision Actually Is

Before spending an hour analysing something, ask -

“How much will this decision actually affect my life?”

A low-stakes decision doesn't deserve the same amount of mental energy as a major life decision.

You can use a simple rule -

Low impact → decide quickly.

High impact → take reasonable time.

Not every decision deserves a courtroom.

Step 2 - Reduce the Number of Options

If you have fifteen options, don't compare all fifteen equally.

Narrow them down to three.

Then compare those three using the things that genuinely matter.

Example

Instead of asking -

“Which of these twenty laptops is the best?”

ask -

“Which three meet my budget, performance needs, and battery requirements?”

Now you're making a decision.

You aren't trying to become an expert on every laptop ever made.

Step 3 - Choose Your Top Three Criteria

Decisions become harder when every factor feels equally important.

Pick your three most important criteria.

For example -

Job decision - salary, growth, work-life balance.

House decision - location, cost, safety.

Course decision - quality, affordability, career relevance.

Everything else becomes secondary.

This reduces mental noise.

Step 4 - Use “Good Enough” Instead of “Perfect”

Ask -

“What would make this a good decision, even if it isn't perfect?”

That question changes the standard.

You don't need the decision that eliminates every possible downside. You need a decision that fits your priorities well enough.

Research on choice and decision-making suggests that extensive searching and large choice sets can sometimes increase avoidance and regret rather than automatically improving outcomes.

So give yourself permission to stop searching when you already have enough information.

Step 5 - Set a Decision Deadline

Indecision grows when the decision has no boundary.

You keep telling yourself -

“I'll decide tomorrow.”

Tomorrow becomes next week.

Then another week.

For decisions that don't require endless research, give yourself a reasonable deadline.

“I'll gather information until Friday, then I'll choose.”

The deadline isn't there to force a perfect answer.

It's there to stop endless analysis.

Step 6 - Separate the Decision From the Outcome

This is one of the biggest mindset shifts.

A good decision does not guarantee a good outcome.

You can make a sensible decision and still experience an unexpected problem.

You can make a reasonable career choice and later discover that the company isn't what you expected.

You can choose a relationship carefully and still experience disappointment.

That's life.

Your responsibility is to make the best decision you reasonably can with the information available at the time.

You are not responsible for controlling every future consequence.

Step 7 - Stop Reopening a Decision Without New Information

You finally choose.

Then your mind says -

“But what if the other option was better?”

This is where many people restart the entire process.

Ask -

“Has anything new happened?”

If the answer is no, you may simply be experiencing post-decision doubt.

You don't need to solve the same decision again unless meaningful new information appears.

Step 8 - Practise With Small Decisions

Self-trust develops through experience.

Start with low-risk decisions.

Choose the restaurant without asking five people.

Buy the item that meets your criteria without reading another forty reviews.

Pick a study schedule and follow it for a week.

Decide what you're going to do this evening and stop reconsidering it every fifteen minutes.

These small experiences teach your brain:

“I can choose, adapt, and handle the result.”

That is more valuable than trying to become 100% certain before every decision.

Step 9 - Notice the Thought Without Automatically Following It

You may hear your mind say -

“What if I'm making a terrible mistake?”

Instead of immediately reopening the decision, notice the thought -

“I'm having the thought that I might be making the wrong choice.”

Then return to the criteria you already decided mattered.

Mind Desk's “What Mindfulness Really Means (A Calm Psychology Explanation)” explains this approach further and shows how mindfulness can help you notice thoughts without automatically reacting to every thought that appears.

The goal isn't to stop doubt from appearing.

It's to stop every doubt from becoming a new decision.

A Simple Decision-Making Reset

WHAT DECISION AM I ACTUALLY MAKING?
↓
HOW IMPORTANT IS IT?
↓
WHAT ARE MY 3 MAIN
CRITERIA?
↓
WHAT ARE MY TOP 3 OPTIONS?
↓
DO I HAVE ENOUGH INFORMATION?
↓
WHAT IS "GOOD ENOUGH"?
↓
SET A DECISION DEADLINE
↓
CHOOSE
↓
DON'T REOPEN WITHOUT
NEW INFORMATION

This doesn't guarantee a perfect choice.

It gives your brain a clear stopping point.

And for someone who tends to overthink, that stopping point can be just as important as the decision itself.

What If You Still Can't Decide?

Sometimes the decision itself isn't the real issue.

Maybe both options are genuinely difficult. Maybe there is no clearly superior choice. Maybe every option has a cost.

Maybe you're trying to choose between what you want and what other people expect from you.

In that situation, more analysis may not solve the problem.

You may need to ask a different question -

“Which trade-off am I more willing to live with?”

Many important decisions are not about finding an option with no downside.

They're about deciding which downside you are willing to accept.

That is a much more realistic way to think about difficult choices.

When Indecisiveness Needs More Attention

Taking time to decide is not automatically a problem.

Pay more attention when indecisiveness becomes frequent and starts interfering with everyday life.

For example, you may -

  1. spend excessive amounts of time on ordinary choices

  2. repeatedly ask other people to decide for you

  3. avoid important decisions until opportunities disappear

  4. constantly second-guess yourself

  5. feel intense anxiety whenever you need to choose

  6. repeatedly reopen decisions you've already made

  7. struggle to act even when you have enough information

  8. experience significant problems at work, school, or in relationships because you cannot decide

Indecisiveness can occur alongside anxiety and other psychological difficulties, but it is not itself a diagnosis. Research also suggests that indecisiveness can involve multiple psychological processes, including uncertainty, perfectionism, and avoidance.

When Should You Talk to a Professional?

Consider talking with a psychologist if difficulty making decisions is causing significant distress or repeatedly interfering with your work, studies, relationships, or daily life.

Professional support can be particularly useful when every decision triggers intense fear, when you rely heavily on reassurance, or when indecisiveness is connected with persistent anxiety, perfectionism, low mood, or other symptoms.

A psychologist can help you understand what's happening underneath the decision itself -

Am I afraid of uncertainty?

Am I afraid of making mistakes?

Do I expect myself to choose perfectly?

Am I trying to avoid regret?

Do I trust my own judgment?

What happens emotionally when I finally have to choose?

Once the underlying pattern is clearer, the goal becomes more specific than simply telling yourself -

“Just make a decision.”

Final Thoughts

Being unable to make decisions does not automatically mean you're weak, lazy, or incapable.

You may simply be trying to get something from a decision that decisions cannot give you:

complete certainty.

You may want to know that you are choosing correctly, that you won't regret it, that nothing will go wrong, that everyone will approve, and that your future self will agree with your present self.

But no decision can promise all of that.

A healthy decision is not necessarily the one with the perfect outcome.

It is often the one you can make reasonably, consciously, and without demanding impossible certainty from yourself.

So the next time you catch yourself thinking -

“Why can't I make decisions?”

try asking -

“Am I missing information—or am I waiting to feel completely certain?”

Those are very different problems.

Once you learn the difference, making decisions can become less about finding the perfect answer and more about learning to trust yourself enough to choose, adapt, and move forward.

Frequently Asked Questions

Why can't I make decisions?

Indecisiveness can have several causes, including difficulty tolerating uncertainty, fear of making the wrong choice, perfectionism, anticipated regret, too many options, decision fatigue, or low confidence in your own judgment.

Why am I so indecisive?

You may be more likely to feel indecisive when choosing feels emotionally risky. If you worry about making mistakes or regret, your mind may keep searching for more certainty before allowing you to choose.

Why do I overthink every decision?

Overthinking can become an attempt to reduce uncertainty. You keep analysing because you hope more thinking will eventually produce complete confidence, but some decisions simply cannot provide that level of certainty.

Is indecisiveness a sign of anxiety?

It can occur alongside anxiety, especially when decisions trigger excessive worry or fear of negative outcomes. However, indecisiveness alone does not mean that you have an anxiety disorder.

Can perfectionism make it hard to make decisions?

Yes. If you believe there is one perfect choice and that choosing incorrectly means failure, even ordinary decisions can become unnecessarily difficult.

What is decision fatigue?

Decision fatigue is a term used to describe the strain associated with repeated or demanding decisions. Research suggests that decisional and situational factors can contribute to this experience, although researchers continue to refine how the concept is defined and measured.

How can I make decisions without overthinking?

Start by deciding how important the choice is, reducing the number of options, identifying your top criteria, deciding what “good enough” looks like, setting a reasonable deadline, and avoiding reopening the decision without new information.

How do I stop second-guessing myself?

Ask whether you have received genuinely new information. If nothing meaningful has changed, recognise that doubt may simply be part of making an uncertain decision. You can acknowledge the doubt without automatically changing your choice.

When should I see a psychologist for indecisiveness?

Consider professional support when difficulty making decisions is persistent, causes significant distress, or interferes with work, studies, relationships, or daily functioning. A psychologist can help identify whether uncertainty, perfectionism, anxiety, avoidance, or another pattern is maintaining the problem.
