Research-Backed Data
Calibration vs. No Calibration
The Real Outcomes
What does skipping calibration actually cost? We pulled the data so you don't have to. G2 reviews, SHRM research, and customer usage — all in one place.
Rating Distribution
Without calibration, ratings cluster at extremes
Managers with inflated standards rate everyone higher. Strict managers rate everyone lower. The result: ratings that say more about the manager than the employee.
Performance Rating Distribution: With vs. Without Calibration
Distribution of employee performance ratings across a 5,000-person organization. Source: SHRM 2024 Performance Management Benchmarks + Confirm customer data.
Without Calibration
Skew: 63% rated Exceeds or Outstanding — grade inflation reduces differentiation
With Calibration (Confirm)
Normal curve: meaningful differentiation. Promotions and top performers are identifiable.
Bias Reduction
Manager bias is structural — calibration removes it
Without calibration, demographic gaps in performance ratings are statistically significant. Calibration sessions, especially with behavioral data, close those gaps by anchoring to evidence.

Legal Risk
Uncalibrated reviews are your biggest employment law exposure
When a promotion or termination is challenged, your defense is the performance record. If that record is inconsistent across managers, it falls apart under scrutiny.
| Risk Factor | Without Calibration | With Calibration (Confirm) |
|---|---|---|
| Discrimination claim defensibility | Weak — inconsistent manager standards expose you | Strong — cross-calibrated ratings + behavioral data trail |
| Wrongful termination evidence | Anecdotal, based on single manager's memory | 12-month behavioral record, calibrated peer comparison |
| Pay equity audit readiness | High risk — rating variance inflates pay gaps | Defensible — ratings normalized before comp decisions |
| Promotion challenge rate | 3.2× higher employee appeals and HR escalations | Normal — decisions backed by calibrated evidence |
| EEOC complaint correlation | Statistically linked to high rating variance across demographics | No statistically significant correlation found in customer data |
| Manager documentation quality | Inconsistent, often written post-hoc to justify decision | Consistent, pre-decision evidence captured continuously |
Process Efficiency
Calibration sessions without data take weeks. With data, hours.
The bottleneck in most calibration processes is arguing about employees nobody has objective data on. Behavioral data eliminates 80% of that debate.
Calibration Process: Time Comparison
Average time per 100 employees, mid-market company
Managers compile anecdotes. No shared evidence. Prep time dominates.
With Confirm: Continuous
ONA data captured year-round. Zero prep time.
Debates dominate. Political advocacy for favored employees.
With Confirm: 90–120 min
Behavior data anchors discussion. Conflicts resolve in minutes.
From 3–4 weeks of calendar time down to under 10 days.
That's ~40 hours of saved HR leader time per review cycle.
Mini Case Studies
What Confirm customers actually experienced
From G2 reviews and verified customer outcomes. Names withheld per agreement; industries disclosed.
"Before Confirm, our calibration sessions were four hours of managers defending their people. After, we ran the same session in 90 minutes because everyone was looking at the same data."
"We found three high performers who had been systematically under-rated because they were remote. The ONA data showed they were in the top 10% for cross-functional influence."
"Our legal team was nervous about the calibration process after an EEOC inquiry. Using Confirm, we produced a complete audit trail for every rating decision. The inquiry went away."
"The bias flagging alone was worth it. We discovered that four managers were rating clinical staff 0.4 points lower than non-clinical peers with identical ONA scores. We corrected it before ratings went final."
"Our prior calibration process consumed 3 weeks of HR calendar every cycle. Now it's 8 days. Our HRBP team went from burned out to actually strategic."
"Confirm made our calibration sessions data-driven for the first time. We could finally see who was actually driving cross-functional work versus who had the loudest manager."
Promotion Fairness
Calibration changes who gets promoted — in the right direction
When calibration is backed by behavioral data, hidden contributors surface. The employees who were getting overlooked for advocacy reasons — not performance — start advancing.
