How to Overcome Perfectionism: Evidence-Based Strategies

9 min read · Reviewed against current psychological research

You’ve read the advice. Lower your standards. Done is better than perfect. Nobody’s looking that closely anyway.

If any of that had worked you wouldn’t be here. And there’s a reason it doesn’t: it aims at the wrong half of the problem.

This guide covers what the trial evidence actually supports, the one habit worth breaking first, and what to do if the pressure isn’t coming from you.

What the evidence supports

Perfectionism is unusual among self-help topics in having a real intervention literature. A systematic review and meta-analysis identified 15 randomised controlled trials of cognitive behavioural therapy specifically adapted for perfectionism, covering 912 participants with a mean age of 23. It concluded that the approach reduces perfectionism, and also reduces symptoms of depression, anxiety and eating disorders.

That second half matters more than it first appears. Treating perfectionism improved other things, which suggests it sits upstream of them rather than beside them.

The effect sizes are worth quoting properly rather than in the abstract. Against control groups, the review reported medium to large effects on perfectionism measures: personal standards g = 0.57, concern over mistakes g = 0.89, and clinical perfectionism g = 0.87 (Galloway et al., 2022).

Notice the gap between the first number and the other two. The intervention moved the fear component substantially more than it moved the standards. That is the treatment doing exactly what the model predicts, and it is also the most reassuring number in this article if you have been worried that working on perfectionism means becoming someone who cares less.

Two honest caveats. The mean age of 23 means much of this was tested on students rather than mid-career adults. And the trials are modest in number and size, so treat the direction as well supported and the precise magnitude as provisional.

The model the treatments are built on

The trials aren’t testing generic therapy pointed at perfectionism. They’re testing a specific model of what perfectionism is, and understanding it makes the strategies below make sense rather than sound arbitrary.

Shafran, Cooper and Fairburn defined clinical perfectionism as the overdependence of self-evaluation on pursuing and achieving demanding standards, in at least one domain that matters to you, despite the costs (Shafran et al., 2002).

Read that definition twice, because the load-bearing word is self-evaluation. What makes perfectionism clinical is not the height of the standard. It’s that your verdict on yourself is wired to whether you meet it.

Their model also describes what keeps it running: the evaluation of the pursuit is biased in a way that guarantees the system never updates. Meet the standard and it gets reclassified as too easy, so the standard rises. Miss it and that confirms you are insufficient. Both outcomes feed the same conclusion, which is why success has never yet fixed this for you.

Every strategy below is aimed at one of those two joints: the wiring between standard and self-worth, or the biased review that keeps it intact.

Aim at the fear, not the standard

This is the single most useful reframe available, and it explains why the popular advice fails.

Perfectionism splits into two components. Perfectionistic strivings are the high standards themselves. Perfectionistic concerns are the fear of falling short and the doubt attached to it. Across the literature, concerns predict distress while strivings often track with self-efficacy and performance.

“Lower your standards” targets strivings. For most people that’s the half doing no harm, which is why the advice feels both wrong and vaguely insulting. The half worth working on is the part that treats a shortfall as information about your worth. Our breakdown of the types of perfectionism goes through the distinction properly.

Step 1: Stop using self-criticism as fuel

Most perfectionists believe, usually without examining it, that the harshness is what makes them good. Take it away and the work gets worse.

Test the belief rather than arguing with it. Think of your best work and ask whether it arrived during a period of self-attack or during one where you were absorbed and reasonably calm. For most people the honest answer undercuts the theory.

This goes first because it’s load-bearing. Every other change gets processed by the same critic, and a critic left running will turn “be less perfectionist” into one more standard you’re failing.

Step 2: Separate the standard from the verdict

The mechanism worth interrupting is the jump from “this fell short” to “I am insufficient.”

When something disappoints you, write the two sentences separately. The output sentence: what was wrong with the thing, specifically. The self sentence: what you concluded about yourself. Seeing them apart on a page makes visible how little the second follows from the first.

Step 3: Run experiments, not affirmations

This is the mechanism the CBT trials lean on, and it works because it produces evidence rather than reassurance.

Pick something low-stakes and deliberately do it to about 80%. Send the email without the third read. Leave the slide with the imperfect alignment. Then record what happened. Not how it felt, what happened.

The prediction your perfectionism makes is specific and testable: that something bad will follow. Most of the time nothing does, and a stack of disconfirming instances moves the belief in a way that telling yourself it’ll be fine never has.

Start smaller than feels meaningful. The point is accumulating data, and a failed experiment at high stakes sets the whole thing back.

Step 4: Notice where the standard came from

Ask whose disappointment you’re imagining when you picture falling short. If it’s a person, or an audience, or a vague sense of being watched, you’re dealing with the socially prescribed dimension.

That matters because individual technique underperforms there. You can restructure your own thinking all you like; it doesn’t change your read of what others require. This is the dimension with the strongest links to depression and distress, and it’s the one where the useful moves are often external: testing the belief against what people actually say, or changing an environment that really does run on comparison.

It’s also the dimension that has risen most sharply over recent decades, which is covered in why perfectionism is getting worse.

Step 5: Widen what you evaluate yourself on

This one follows directly from the clinical definition and it is the most structural change available.

If self-evaluation depends on performance in one salient domain, then everything rides on that domain. A bad quarter at work is not a bad quarter, it is a referendum. The fix is not to care less about the domain but to have more than one.

Practically: notice what proportion of your sense of being an adequate person is currently sourced from a single area. For a lot of people the honest answer is most of it, and often from work specifically. Deliberately investing in a domain where you have no standards to meet, and no intention of getting good, does real structural work. Not as a hobby to optimise. As a place where the question of whether you are performing well does not arise.

This is slow and it is the change most likely to still be there in five years.

What tends not to help

Lowering your standards. Targets the wrong component and feels like being asked to care less about your work, which most people correctly refuse.

Positive affirmations. The perfectionist mind treats an unevidenced claim about yourself exactly as it treats an unevidenced claim about anything, which is to say it discounts it.

Becoming perfect at recovering from perfectionism. If you’ve built a tracking system for your imperfection practice, the pattern has absorbed the treatment.

Can you do this without a therapist?

Partly, and the evidence here is better than for most self-directed mental health work.

Guided self-help versions of CBT for perfectionism have been tested in randomised trials, delivered over the internet with a therapist providing support rather than sessions. Two such trials, one in Sweden and one in the UK, together randomised participants to guided self-help or a waitlist and followed them up afterwards (Rozental et al., 2018).

The word doing the work is guided. These were not apps you use alone. Someone was reading what participants wrote and responding, which is a meaningfully different thing from a workbook.

So the realistic reading: the structured content of these programmes can be delivered at a distance and in writing, which is encouraging if cost or access is the barrier. Reading an article, including this one, is not the same intervention, and it would be dishonest to imply otherwise.

When to talk to a professional

Perfectionism isn’t a diagnosis and there’s no threshold to clear before it’s worth addressing.

Worth raising with someone qualified: if falling short reliably produces shame rather than disappointment, if the standards are visibly costing more than they return, or if the pattern comes with persistent anxiety, low mood, or disordered eating. This is also one of the areas where the evidence points clearly at professional help rather than self-directed work, given that the trials tested therapist-delivered and guided programmes rather than reading an article.

The takeaway

The goal was never to care less. It’s to stop treating every shortfall as a verdict, which is a narrower and more achievable operation than the usual advice implies.

That distinction is also why this is worth doing rather than tolerating. The standards can stay. What goes is the tax you pay on them, which is the part quietly costing you sleep, enjoyment of your own work, and in the trial data a measurable amount of anxiety and low mood.

Start with the self-criticism. Everything else is downstream of whether the critic is still running the review. Our full guide to perfectionism covers the wider picture, and the signs are worth reading if you’re still not sure this describes you.
