Performance Reviews Are Vibes in a Trench Coat
Let’s be honest about what they are.
You know what performance reviews really are? They’re vibes in a trench coat, pretending to be a rigorous, objective evaluation process. We dress them up with competency matrices, rating scales, and calibration meetings. We talk about them like they’re scientific. Data-driven. Fair.
But strip away the corporate theatre and you’ll find something much simpler: your manager’s gut feeling about you, justified after the fact with whatever evidence supports that feeling.
The Illusion of Objectivity
Let’s start with the obvious lie. Performance reviews claim to measure your work objectively. You get rated on competencies like “communication” or “leadership” or “technical execution.” There are helpful definitions for each rating level. Look, we even have a rubric!
Except nobody actually uses the rubric the way it’s written. Your manager already knows what rating they want to give you. The rubric is just there to make that rating look defensible. It’s not a measurement tool. It’s a justification engine.
I’ve sat through enough calibration meetings to see how this works. A manager comes in ready to give someone a high rating. Someone else asks for examples. The manager rattles off a few things. The group nods. Rating approved. Then another manager wants to give someone else the same high rating. They provide similar examples. But this time, someone pushes back. “That doesn’t seem like enough for that rating.” The examples get picked apart. The rating gets lowered.
Same quality of examples. Different outcomes. Why? Because the room had different vibes about the two people.
The Performance Review Playbook
Here’s how performance reviews actually work in most organizations:
Your manager forms an opinion about you based on the last few months of working together. Maybe the last few weeks, if they’re particularly forgetful or busy. That opinion is largely vibes. Do they like working with you? Do you make their life easier or harder? Do you remind them of someone they used to work with? How did that one project go that they remember clearly?
Then your manager sits down to write the review. They already know what rating they want to give you. Now they need to justify it. So they go looking for evidence. If they think you’re great, they’ll remember all the times you did great work. If they think you’re struggling, they’ll remember all the times you struggled. Confirmation bias is a hell of a drug.
The really good managers are at least aware they’re doing this. They’ll try to balance it out. Look for contradicting evidence. Check their assumptions. The mediocre managers just run with their gut and call it performance management.
The Calibration Theatre
Then comes calibration, where a group of managers get together to “ensure consistency” across ratings. In theory, this is where we catch bias and make sure everyone’s being evaluated fairly.
In practice, it’s where managers horse-trade and play politics.
“I’ll support your high rating for Sarah if you support mine for Tom.” “I can’t have two people on my team in the top rating because HR says we need a curve.” “This person is definitely getting promoted next cycle, so we need to justify it now with this rating.”
The strongest personalities in the room have outsized influence. If you’re a new manager, good luck pushing back on the senior director who’s been at the company for eight years. If you’ve got a VP in your corner, your direct reports are probably getting better ratings than the person whose manager is conflict-averse.
None of this has anything to do with actual performance. It’s all vibes and power dynamics.
The Feedback Lag Problem
Even if we could magically make performance reviews objective, they’d still be useless for actually improving performance. You know why? Because they’re retrospective.
You’re getting feedback on things that happened months ago. Maybe six months ago if you’re on an annual cycle. By the time you hear about it, the moment has passed. The project is done. The stakeholders have moved on. You can’t go back and do it differently.
Good feedback is immediate. You do something, your manager tells you how it landed, you adjust. That’s how people actually learn and grow. Not by reading a document once a year that tells them they need to “communicate more proactively” or “demonstrate more strategic thinking.” What the fuck does that even mean in practice?
Performance reviews turn feedback into this big formal thing that happens on a schedule. And because it’s formal and scheduled, managers save up all their feedback for review time instead of just telling you things when they happen. So you spend months doing something your manager doesn’t love, and you don’t find out until it’s already affected your rating.
It’s the worst possible way to help someone improve.
The Real Purpose
So if performance reviews don’t actually measure performance objectively, and they’re terrible at improving performance, what are they for?
They’re for documentation and liability management.
Companies need performance reviews so they can justify their decisions about who gets promoted, who gets raises, and who gets fired. It’s much harder to sue for wrongful termination if the company has a paper trail showing your performance was documented as inadequate.
They need calibration so they can say they have a consistent, fair process. When someone complains about their rating, HR can point to the calibration meeting and say, “Multiple managers reviewed your case.” Never mind that those managers barely know you and were mostly just going along with what your manager said.
The entire system is designed to protect the company from legal risk and give managers a structured way to make the decisions they were already going to make. Everything else is just set dressing.
What Actually Matters
Here’s the thing that makes all of this extra frustrating: your manager’s vibes about you actually do matter. They matter a lot.
If your manager thinks you’re great, you’ll get better projects, more opportunities, and more support when things go wrong. If your manager thinks you’re struggling, you’ll get more scrutiny, less autonomy, and fewer chances to prove yourself. Performance reviews don’t create this dynamic. They just formalize it and pretend it’s objective.
The real work of managing your career isn’t optimizing for the performance review rubric. It’s managing your manager’s vibes about you. Which means the normal stuff: do good work, be easy to work with, communicate clearly, and don’t create unnecessary problems. Make your manager look good to their manager. Be the kind of person they want to fight for in calibration meetings.
Is this fair? Fuck no. Should your career depend on whether your manager happens to vibe with you? Absolutely not. But that’s how it works. Performance reviews just add extra steps and paperwork to a fundamentally subjective process.
A Better Way Forward
Look, I’m not saying we should blow up performance reviews entirely. Some amount of formal feedback and documentation is probably necessary, even if just for legal reasons. But we should at least be honest about what they are and aren’t.
They aren’t objective measurements of performance. They’re formalized records of subjective opinions, influenced by recency bias, availability bias, and organizational politics. The sooner we admit that, the sooner we can stop pretending the process is something it’s not.
And maybe, just maybe, we can start putting more energy into actual performance management. Regular feedback. Clear expectations. Real conversations about growth and development, not once a year, but ongoing. You know, the stuff that might actually help people improve.
But that would require managers to do more work and companies to give up the illusion of objectivity. So I’m not holding my breath.
In the meantime, just remember: when performance review season rolls around, your manager is going to decide what they think about you first, and justify it second. That’s not a bug in the system. That’s the system.
The trench coat is just there to make the vibes look official.
