Types of Rater Bias That Can Be Addressed with Effective Training
Performance reviews are an essential part of the employee management process. They provide an opportunity for managers to assess their employees’ performance, provide feedback, and set goals for the future. However, performance reviews can also be biased, which can lead to unfair or inaccurate evaluations.
Key Facts
- Recency bias: This bias occurs when a rater focuses on the most recent performance of an employee and overlooks their overall performance.
- Primacy bias: Primacy bias refers to the tendency to give more weight to the initial impressions of an employee, which can overshadow their subsequent performance.
- Halo/horns effect bias: This bias occurs when a rater allows one positive or negative trait of an employee to influence their overall evaluation, leading to an inflated or deflated rating.
- Centrality/central tendency bias: Centrality bias refers to the tendency to rate most employees in the middle of the rating scale, making it difficult to differentiate between high and low performers.
- Leniency bias: Leniency bias occurs when a rater consistently gives high ratings to all employees, making it challenging to identify top performers and provide appropriate rewards.
- Similar-to-me bias: This bias involves giving higher ratings to employees who share similar interests, skills, or backgrounds with the rater, potentially leading to a less diverse and inclusive evaluation process.
- Contrast bias: Contrast bias occurs when a rater compares an employee’s performance to others rather than evaluating them based on their own merits, leading to unfair evaluations.
There are many different types of rater bias that can affect performance reviews. Some of the most common types of bias include:
- Recency bias: This bias occurs when a rater focuses on the most recent performance of an employee and overlooks their overall performance.
