Curran's mechanism for why perfectionism damages rather than drives. It begins not with ambition but with deficiency: I am not good enough, so I must prove otherwise. That produces standards deliberately set beyond reach, which guarantees shortfall. Shortfall reads as public failure, so anxiety rises and self-esteem drops. The perfectionist overcompensates by raising standards further, which produces more failure, and the loop accelerates and entrenches. The spiral has two performance consequences documented in his lab and in the literature: working past the point of diminishing returns while sacrificing sleep, diet and exercise, and withdrawing effort entirely once failure looks likely, because you cannot fail at something you did not try. In real life that withdrawal looks like procrastination. Breaking the loop means addressing the deficit, not the standards.

How to run it
- 1
Identify the deficit at the start of the loop
The spiral does not begin with ambition. It begins with a worldview: I'm not good enough, I'm not perfect enough, and therefore I must prove to other people that I'm worth something. Everything downstream is an attempt to manage that starting premise.
Pro tip Ask what a given standard is for. If the honest answer is proof of worth rather than a result you want, you are in the loop.

Watch the standards get set beyond reach
To prove worth you must excel, so standards climb to levels that are, by design, too high. Curran is blunt that this sets you up for failure, and that even an objectively high grade can feel disappointing because the better you do, the better you are expected to do.
Watch out Excessive expectations churn permanently ahead of reality, so the standard moves every time you reach it.
- 3
Notice the shortfall converting into shame
When the standard is missed, the perfectionist does not read it as a missed standard but as looking like a failure to other people. Anxiety spikes, self-esteem plummets, and the setback is overgeneralised to the self: there must be something wrong with me, I'm flawed and irredeemable.
Pro tip Name the overgeneralisation out loud. The event is a result; the story is about your worth.

Catch the overcompensation
To escape those feelings the perfectionist raises standards further, which produces more failure, more anxiety, lower self-esteem. Curran calls this a negative downward spiral that gets entrenched and accelerates with every setback. Overwork past diminishing returns and sacrificed sleep, diet and exercise are part of this stage, and burnout correlates strongly.
Watch out Extra input past the point of diminishing returns buys nothing; the data shows no relationship between perfectionism and performance.

Spot the withdrawal, which looks like procrastination
Once failure looks certain, effort collapses, because you cannot fail at something you did not try. In the lab that is effort dropping off a cliff on the second attempt. In real life it is Netflix, TikTok recipes and anything else that defers the anxiety-provoking task until the work goes in late or substandard.
Pro tip Treat sudden avoidance of an important task as a failure-probability signal, not a motivation problem.
Watch out Avoidance genuinely eases anxiety in the moment, which is exactly why it is so hard to interrupt.

Intervene at the deficit, not the standards
Because the loop is powered by deficiency, lowering standards alone does not stop it. Curran's exits are self-acceptance and self-compassion, accepting that a jagged path with plateaus and regressions is normal, and letting the anxiety sit next to you while you keep going toward the goal.
Pro tip Understanding that the deficit is culturally manufactured takes power away from it.
In the wild
Curran's team gives participants a cycling target they should comfortably hit, and lets them work hard at it. At the end they are told they did not quite make the target. Then, as Curran puts it, they do something really naughty: they ask them to try again. Highly perfectionistic participants, ashamed and embarrassed by the failure feedback, see their effort drop off a cliff on the second attempt. Less perfectionistic participants show no change, or slightly more effort. The design isolates withdrawal as the mechanism rather than ability or motivation.
→ Perfectionists systematically withhold effort once failure looks likely, which is why hard work does not convert into performance.
Curran admits his own book on perfectionism ran two years late and that he believes his editor was ready to throttle him, since he was still tinkering the day before it went to press. His diagnosis of himself is the same spiral: perfectionists cannot help tinkering and iterating because they find it psychologically challenging for the work not to be perfect, so they work too hard, put things off, and manage anxiety in suboptimal ways. He knows done is better than perfect and still finds it tough.
→ Deadline slippage and last-minute tinkering as the visible output of the withdrawal stage.
Common mistakes
Fixing the standards, not the deficit
Lowering a target while the underlying premise is still I have to prove I'm good enough just resets the loop at a new altitude. The standards are a symptom of deficit thinking, not its cause.
Reading withdrawal as laziness
The procrastination stage looks like a discipline failure and is actually shame avoidance. Treating it with more pressure raises the failure stakes and deepens the withdrawal.
Assuming perfectionism produced the success
Conventional wisdom points at self-confessed perfectionists at the top of their fields and credits the perfectionism. Curran's data finds no relationship between perfectionism and performance; those people succeeded with the trait, not because of it.
From the transcript
“But what we're doing is we're setting ourselves up for failure because those excessive standards are too high.”
“we strive for even higher standards, which means we fail more, which means we feel more anxious”
“Because you can't fail at something you didn't try.”
