How to Stop Overthinking Decisions: A 7-Step Method

Why do you overthink decisions?

You overthink a decision when more thinking feels safer than committing. While the question stays open, you can’t be wrong and you haven’t lost any option. The thinking feels responsible, so it never registers as avoidance.

Three causes do most of the work, and each one needs a different fix:

The third cause is loss aversion at work: every option you reject feels like something taken from you, so rejecting nothing feels best.

Overthinking vs careful thinking: how do you tell?

Careful thinking produces something new, and overthinking doesn’t. That is the whole test. Psychologists call the repetitive version rumination: Susan Nolen-Hoeksema spent much of her career showing that going over the same material tends to deepen a low mood rather than solve anything.

How to stop overthinking a decision in 7 steps

These steps assume you have one real decision in front of you. Open a note and write as you go, because a loop that stays in your head can run forever and a loop on paper repeats itself where you can see it.

1. Write the decision in one sentence. “Should I take the offer from Company B by Friday?” If you can’t do this, you may be chewing on several decisions at once. Split them and take one.
2. Score how much thinking it deserves. Use the Decision Weight Score: rate Reversibility, Impact and Uncertainty from 1 to 3. A score of 1 to 3 means decide in under 10 minutes. A score of 4 to 6 means about an hour. A score of 7 to 10 means the full process and a night’s sleep.
3. Set a stopping rule. Pick a deadline, then write the one thing you still need to learn. Stop gathering information when you have it, or when the deadline arrives, whichever comes first.
4. Define good enough before you look. Write three or four requirements an option must meet. The first option that meets them wins. Herbert Simon called this satisficing, and it is the direct cure for “there might be something better.”
5. Cut the list to two or three. More options means more comparing, as Hick’s law describes for simple choices. Drop anything that fails a requirement, and don’t bring it back.
6. Turn the remaining doubt into a test. Ask what small, reversible step would show you something thinking can’t. Talk to someone who made this choice. Rent before you buy. Try it for a week.
7. Decide, write it down, close the file. Record the choice, your reasons and your confidence as a percentage, then set one date to review it. Until that date, the decision is closed. A decision journal is built for this.

The steps also run in a stripped-down version. For a low-score decision, step 1, step 4 and a choice is enough.

How much thinking does a decision actually deserve?

Much less than it feels like, in most cases. Here is how a few hypothetical decisions score. The formula is R × I × U ÷ 27 × 10, rounded, with a minimum of 1.

Notice that reversibility pulls most of these down. Very few decisions rate a 3 on it. Jeff Bezos made the same point in his 2015 letter to Amazon shareholders, separating consequential, nearly irreversible Type 1 decisions from Type 2 decisions that can be changed. His warning was that organizations tend to run the heavy Type 1 process on everything.

A score isn’t a verdict, and you can overrule it. Its job is to give you an outside opinion when your nerves have inflated the stakes.

When do you have enough information to decide?

You have enough when no answer you could still find would change your choice. Before you do more research, ask: “What could I learn that would make me pick differently?” If you can’t name it, stop. If you can name it, go get that one thing and nothing else.

Bezos put a rough number on this in his 2016 shareholder letter: most decisions should probably be made with about 70% of the information you wish you had, because waiting for 90% usually means you are being slow. Treat that as a rule of thumb from a business leader, not a measured threshold. The useful part is the admission that the feeling of certainty isn’t coming, and that waiting for it has a cost.

The cost of delay belongs in the comparison. The job offer expires, the price changes, the team waits, and your attention stays tied up. In expected value terms, another week of research is worth it only if it improves the decision by more than the week costs.

Why does looking for the best option backfire?

Trying to find the best option tends to get you a slightly better result and a worse feeling about it. Barry Schwartz and colleagues (2002) distinguished maximizers, who look for the best, from satisficers, who look for good enough. Maximizers reported less happiness and more regret. A later study by Sheena Iyengar, Rachael Wells and Schwartz (2006) followed graduating job seekers and found that maximizers landed higher starting salaries but felt worse about the outcome.

There is a second trap after you choose. Daniel Gilbert and Jane Ebert (2002) found that people preferred keeping the option to change their mind, yet were less satisfied with what they chose when they kept it. Leaving a decision open feels like freedom, and it keeps you comparing.

That is why step 7 says to close the file. A set review date lets you stop reopening the question without pretending it can never be revisited.

3 examples of overthinking, and the way out

These are hypothetical, but the patterns are common.

Career

Say you have a job offer and you have made the same pros and cons list three times. The list hasn’t changed, so the problem isn’t missing data. The DWS comes out at 4, so you give yourself one more hour and one question: what would change your mind? The answer is what the manager is like to work for. Two calls with people on that team settle it by Thursday.

Business

Say a founder has spent three weeks comparing email tools. It scores a 3, and a switch would be annoying but possible. The founder writes three requirements, picks the first tool that meets them, and notes a review date in six months. Three weeks of research was the most expensive part of the decision.

Personal purchase

Say you have 14 tabs open on one sofa. You write your limits: under your budget, fits the room, delivered this month, free returns. Four sofas pass. You cut to two by the one that matters most and buy it. The free return is what makes this safe, because it makes the choice reversible.

What to do when you keep reopening a decision

Second-guessing after a decision is a separate loop, and it needs a different move. You aren’t short of information; you are short of closure.

• Check your note. You wrote down what you knew and why you chose. Ask whether anything has actually changed since then. If not, the doubt is a feeling and not a fact.
• Save it for the review date. Write the new thought down with the date and leave it for then. Writing it down usually quiets it, because you no longer need to hold it in your head.
• Separate decision from outcome. A good decision can turn out badly through luck. Judge the reasoning, not the result.
• Check your energy. Doubts grow late in the day and after a long run of choices. Decision fatigue has an uneven research record, but tired judgment is a fine reason to postpone a re-decision until morning.

If you are stuck for a deeper reason, such as each option costing something you care about, more process won’t fix it. The guide on how to make a hard decision covers that case. For a structured partner, the free Mentarium Decision Coach runs the Decision Loop with you inside Claude or ChatGPT.

The Mentarium take

Most advice treats overthinking as a mood problem: breathe, go for a walk, trust your gut. Those can help you feel better for an hour. They don’t change the fact that the decision is still open, and an open decision will call you back.

Our view is that overthinking is mostly a missing rule. Nobody said how long this deserves, what counts as good enough, or what would end the search. So the search has no natural end, and it runs until something external forces a choice or until you run out of energy.

Set those three things before you start and the problem gets smaller. The doubt won’t vanish, and you should stop waiting for it to. Feeling sure is not a condition for deciding. Most good decisions are made while still a little unsure, and then made to work.
