Five Perfect Reviews, One Bad One. Guess Which One Keeps You Up at Night?

You just finished a 10-hour shift. On your way out, you stop by the front desk to grab your things, and the receptionist hands you a stack of papers.

“Patient satisfaction surveys from this week,” she says.

You flip through them in your car.

“Michelle was so kind and thorough—5 stars”

“Best PA I’ve ever seen—took time to really listen—5 stars”

“Explained everything in a way I could understand—5 stars”

“Felt rushed. She didn’t seem to care about my concerns—2 stars“

“Professional and knowledgeable—5 stars”

“Great experience, will definitely request her again—5 stars”

Six surveys. Five glowing reviews. One criticism.

Which one will you be thinking about at 11 PM tonight? At 2 AM, when you can’t sleep? Tomorrow morning, when you’re driving to work?

Not the five people who felt cared for and helped. The ONE person who felt rushed.

You’ll replay that appointment in your head frame by frame. What did I say wrong? Should I have spent more time? Am I really that uncaring? Maybe I’m not cut out for this.

The five wins? They’ve already evaporated from your memory.

Welcome to negativity bias, your brain’s annoying evolutionary feature that’s making you miserable.

Your Brain Is Working Against You (And It’s Not Your Fault)

Here’s what nobody tells you: Your brain is wired to remember threats, mistakes, and criticism far more vividly than successes, compliments, and wins. This isn’t a character flaw. It’s neuroscience.

Psychologist Rick Hanson describes it perfectly: “The brain is like Velcro for negative experiences and Teflon for positive ones.”

Why? For our ancestors, remembering where the tiger attacked was more critical for survival than remembering where the berries were sweet. The cost of ignoring danger was death. The cost of ignoring something pleasant was just a missed opportunity.

Your brain evolved to prioritize negative information because it kept you alive.

But here’s the problem: You’re not running from tigers. You’re practicing medicine. And in modern clinical practice, negativity bias doesn’t protect you; it destroys you.

The Research That Changes Everything

Psychologist Roy Baumeister’s research revealed something startling: it takes approximately five positive experiences to counterbalance one negative experience.

Think about that. One criticism from your attending requires FIVE compliments to neutralize its emotional impact. One mistake requires FIVE wins to restore your confidence.

No wonder you feel like you’re failing even on objectively good days.

Here’s what this looks like in your clinical life:

What actually happened today:

• Correctly diagnosed four patients
• Gave excellent patient education that led to visible relief
• Caught an abnormal EKG before the patient decompensated
• Received thanks from 3 different patients
• Made one documentation error

What your brain remembers:

• That documentation error (in vivid, painful detail)

Your brain isn’t giving you an accurate picture of your performance. It’s giving you a threat-detection report. And if you don’t actively counter this bias, you’ll start believing the distorted version.

Why This Is Destroying Your Confidence (And Your Career)

Negativity bias doesn’t just make you feel bad. It has measurable consequences on your clinical development:

1. It creates a false narrative of incompetence When you only encode and remember failures, you build a story about yourself that says, “I’m not good at this.” Even when the data shows otherwise.

2. It prevents learning from success You spend hours analyzing what went wrong, but zero time analyzing what went right. This means you can’t replicate your wins or understand your strengths.

3. It accelerates burnout Research from positive psychology founder Martin Seligman shows that a chronic focus on negative events is one of the strongest predictors of depression and burnout.

4. It makes you risk-averse When mistakes feel catastrophic, you start practicing defensive medicine. You order unnecessary tests. You avoid complex patients. You stop growing.

The irony? The PAs most plagued by negativity bias are often the most conscientious, careful clinicians. Your attention to what could go wrong is part of what makes you good at this job. But unchecked, it becomes the thing that drives you out of it.

The Positive Psychology Solution: Retraining Your Brain

Here’s the good news: Neuroplasticity means your brain can change. You can literally rewire the neural pathways that determine what you notice, remember, and internalize.

Positive psychology isn’t about toxic positivity or pretending everything is fine. It’s about correcting the distortion, helping your brain see reality more accurately, rather than through a threat-detection filter.

Let me show you how.

Three Practices to Rewire Negativity Bias

Practice #1: The Three Good Things Exercise (5 Minutes Daily)

This is the single most researched positive psychology intervention for countering negativity bias. Developed by Martin Seligman at UPenn, it’s deceptively simple:

Every evening, write down three things that went well today and why they went well.

But here’s the key for clinicians: Make them clinical moments.

Not this:

• “I had a good day”
• “My patient was nice”
• “I didn’t make mistakes”

But this:

• “I recognized that my patient’s chest pain pattern didn’t fit typical angina, which led me to consider PE; my clinical reasoning is developing.”
• “I took extra time to explain a diagnosis to an anxious patient, and I could see her relax; my communication skills made a difference.”
• “I asked my attending for help before I was completely stuck; I’m learning to identify my limits appropriately.”

Notice the difference? The second version is specific AND explains why it went well. This trains your brain to:

1. Notice positive clinical moments in real-time
2. Attribute them to your developing skills (not luck)
3. Encode them into long-term memory

The research: In Seligman’s studies, participants who did this exercise for just one week were happier and less depressed, not just immediately, but six months later. Your brain literally begins scanning for positive experiences throughout the day because it knows you’ll write them down later.

Practice #2: The Positive Event Savoring Protocol (2 Minutes Per Win)

Negativity bias works because negative experiences automatically activate your amygdala (threat center) and create strong emotional memories. Positive experiences? They pass right through unless you deliberately pause to encode them.

Here’s how to “install” positive experiences (Rick Hanson’s term):

When something good happens:

Step 1: NOTICE it (10 seconds) “That patient just thanked me for listening. That was a positive moment.”

Step 2: SAVOR it (20 seconds) Stay with the feeling. What does appreciation feel like in your body? Where do you feel warmth or lightness? Let yourself actually experience the win.

Step 3: ABSORB it (30 seconds). Imagine this positive experience sinking in, becoming part of your clinical identity. “I’m the kind of PA who takes time to listen. Patients notice and appreciate this about me.”

This sounds hokey. I get it. But neuroscience backs this up: Positive experiences need 10-20 seconds of focused attention to transfer from short-term to long-term memory. Negative experiences? They’re encoded automatically and instantly.

You’re not inflating your ego. You’re leveling the playing field.

Practice #3: The Mistake-to-Learning Reframe (After Every Error)

Your negativity bias wants you to ruminate on mistakes. Positive psychology offers an alternative: the benefit-finding process.

When you make a mistake, your default brain response is:

• Replay it on loop
• Globalize it (“I’m terrible at this”)
• Catastrophize it (“I’ll probably hurt someone”)

Instead, try this structured reflection:

1. Acknowledge the negative emotion (30 seconds) “I feel embarrassed/scared/incompetent right now. That’s valid.”

2. Extract the learning (2 minutes) “What specifically can I learn from this? What will I do differently next time? What system can I put in place to prevent this?”

3. Find the benefit (1 minute) “What’s one positive thing that came from this mistake?”

Wait, positive? From a mistake?

• “I caught this before it reached the patient.”
• “My attending’s correction taught me something I’ll remember forever”
• “This revealed a gap in my knowledge I can now address.”
• “I’m building my mistake-recovery skills, which every clinician needs.”

Research from positive psychologists shows that benefit-finding after negative events is one of the strongest predictors of resilience and growth. You’re not minimizing the mistake. You’re refusing to let it become your entire identity.

What 32 Years Taught Me About Remembering Wins

In my fifteenth year as a PA, I kept a “Good Catch” journal. Every time I made a diagnosis that could have been missed, every time a patient specifically thanked me, every time I taught a student something valuable, I wrote it down.

At the end of the year, I had 347 entries.

I would have remembered exactly zero of them without writing them down. But I would have remembered every single mistake.

Here’s what shocked me: When I read through that journal, I barely recognized some of the entries. “Did I really do that?” My brain had completely discarded evidence of my competence because it didn’t fit the threat-detection narrative.

That journal became my counter-narrative. When imposter syndrome whispered “You don’t know what you’re doing,” I had documented proof that I did.

I still keep one. After 32 years, my brain still defaults to the negative. But now I have a practice that corrects for it.

The Negativity Bias Reality Check

Let me be clear: I’m not asking you to ignore mistakes or pretend everything is perfect. Clinical errors matter. Learning from failures is essential.

But here’s the reality check you need:

If you’re dwelling on mistakes, you’re NOT learning from them more effectively. You’re just suffering more.

Research shows that rumination (repetitive negative thinking) actually IMPAIRS learning and problem-solving. It activates your stress response, which shuts down the prefrontal cortex, the part of your brain that you need for clinical reasoning.

The PAs who learn best from mistakes are the ones who:

1. Acknowledge the error
2. Extract the lesson
3. Implement the change
4. Move on

They don’t ruminate. They learn and release.

Meanwhile, they’re ALSO actively encoding their wins, which builds the confidence and self-efficacy needed to take appropriate clinical risks and continue developing expertise.

Your Assignment This Week

Here’s your challenge:

For the next 7 days, keep a “Clinical Wins” note on your phone.

Every time something goes right, even small things, add it to the list:

• “Remembered the dosing without looking it up”
• “Patient said I made them feel heard.”
• “My assessment matched my attending’s”
• “I stayed calm during a difficult patient interaction.”

At the end of the week, count them.

I bet you’ll have 30-50 wins you’d otherwise forgotten.

That’s not toxic positivity. That’s accurate accounting.

Your brain has been keeping receipts of every failure. It’s also time to keep receipts of every success.

You’re not failing as much as your brain says you are. You’re succeeding far more than your brain lets you remember.

The PAs who thrive aren’t the ones who never make mistakes. They’re the ones who’ve learned to weigh their wins and losses accurately.

Stop letting your negativity bias write your story. Start collecting the evidence of your competence.

This week, I challenge you: Write down three clinical wins every evening. Come back here in 7 days and share one thing you learned about yourself. Let’s rewrite the narrative together.
