*Biases that cause decisions to be influenced by less relevant information.*
[Recency Bias](http://en.wikipedia.org/wiki/Recency_bias#Recency_effect): Over-weighting the most **recent information** (e.g., projects at the end of the quarters)
- Consider concrete data points from throughout the review period.
[Halos & Horns](http://en.wikipedia.org/wiki/Halo_effect): Over-weighting a **general impression** (e.g., overall positive/negative feelings)
- Consider concrete, behavioral examples over review period
[Recall Bias](http://en.wikipedia.org/wiki/Availability_heuristic): Over-weighting information that **comes to mind easily** (e.g., big, flashy projects)
- Review archives (bugs, project plans) for more examples over review period
[Fundamental Attribution Error](http://en.wikipedia.org/wiki/Fundamental_attribution_error): Over-weighting **personal explanations** for performance; under-weighting situation-based explanations for performance (e.g., poor ability vs. lacked resources)
- Consider context or situational factors that affected performance

## Motivational biases
*Biases that cause decisions to be influenced by desires and goals.*
**Central Tendency**: Choosing a middle rating in order to play it safe and avoid risk
- Provide justification, especially when scores hover around the middle
**Agreement Bias**/Spiral of Silence: Agreeing with others to avoid conflict

**Self-serving Bias**: Inflating ratings of employee to make self look good
**Similar-to-me Error**: Rating employee highly based on similarities to you in order to self-enhance
