Growing up as a minority in a predominantly white community, I often felt like I had to work harder than my peers to prove myself. I felt like I had to go above and beyond to be seen as equal or even just competent. This bias was not just limited to my peers, but it was also present in the form of institutionalized racism and discrimination. I have also noticed my own biases when interacting with others. I have caught myself making assumptions about people based on their appearance, accent, or cultural background. It is a natural tendency to make snap judgments, but I have learned to be mindful of these biases and challenge them.
These algorithms are created by humans, and they can be influenced by human biases, whether intentional or not. For example, if a dataset used to train a machine learning model is biased towards a certain group, the model will inevitably produce biased results. The good news is that being aware of bias is the first step to reducing its impact. By acknowledging our own biases and challenging them, we can make more informed decisions and interact with others more fairly. Similarly, by identifying and correcting biases in algorithms and data, we can work towards creating more equitable systems.
What is bias?
Bias is a tendency or inclination, often unconscious, that can affect the way we think, behave or make decisions. It can be influenced by a variety of factors such as personal experiences, cultural background, education, beliefs, and values. We can all have biases, and they can be positive or negative, but when they are negative, they can lead to unfair treatment or discrimination towards others. It is important to recognize our biases and work to minimize their impact, especially in situations where objectivity and fairness are critical.
Why is addressing biases in the performance review important?
Addressing biases in performance reviews is important because biases can lead to unfair evaluations of an employee’s performance. Biases can come in many forms, such as gender, race, age, and personal preferences, among others. These biases can result in an employee receiving either a higher or lower score than they deserve based on their actual performance. For example, if a manager has a personal preference for extroverted employees, they may give higher marks to those who are outgoing, even if their work is not as good as a more introverted employee. This can lead to an unfair review that does not accurately reflect the employee’s performance. Addressing biases in performance reviews is crucial for creating a fair and equitable workplace. When employees are evaluated based solely on their actual performance, they are more likely to feel valued and motivated to perform their best. This, in turn, can lead to greater employee engagement and productivity.
Furthermore, addressing biases in performance reviews is essential for promoting diversity and inclusion in the workplace. If biases are allowed to persist, it can lead to an environment where only certain types of employees are recognized and rewarded, while others are overlooked. Addressing biases can help ensure that all employees have an equal opportunity to succeed and thrive in the workplace. In conclusion, addressing biases in performance reviews is crucial for creating a fair and equitable workplace that values diversity and inclusion. By recognizing and minimizing the impact of biases, employers can help ensure that all employees are evaluated based solely on their actual performance, leading to greater employee engagement and productivity.
10 biases that affect performance reviews
1. Recency bias
Recency bias is a psychological phenomenon that affects our ability to make objective judgments about events or people based on their most recent or readily available information. It is a tendency to rely too heavily on recent experiences, rather than considering the full range of information available.
Recency bias can occur in many areas of life, including business, politics, sports, and personal relationships. For example, a hiring manager might be more likely to hire a candidate who had a strong interview performance, even if their previous work experience is not as impressive. A sports commentator might praise a player who had a good game, even if their previous performances were mediocre. For example, if a user has a negative experience with a particular feature or functionality, they might assume that it is always problematic, even if it has been improved in subsequent updates. This can lead to a reluctance to use that feature or even the entire platform.
2. Primacy bias
Primacy bias is a cognitive bias that affects our ability to make objective judgments based on the order in which information is presented. It refers to the tendency to remember and be influenced more by the first information presented, rather than the later information presented. This bias can manifest in many areas of life, including marketing, politics, and personal relationships. For example, a political candidate who speaks first in a debate may have an advantage over their opponents, as their message is more likely to stick in the minds of the audience. Similarly, a marketer may be more successful in selling a product if they emphasize its positive qualities first.
For example, if a user is introduced to a new feature or functionality, they may be more likely to use it if it is presented to them first. Conversely, if a user is presented with a feature after having used the platform for a long time, they may be less likely to adopt it.
3. Halo/horns effect bias
The halo/horns effect is a cognitive bias that occurs when our perception of one trait of a person colors our judgment of their other traits. It can happen when we have either a positive or negative overall impression of a person based on a single trait or characteristic, and it influences our perception of that person’s other qualities and abilities. For example, if we see someone who is physically attractive or successful, we may automatically think of them as being kind, intelligent, and competent in other areas. This is known as the halo effect. Conversely, if we perceive someone to be unattractive or unsuccessful in one area, we may assume that they are also unkind, unintelligent, or incompetent in other areas. This is known as the horns effect.
For example, if a user has a positive experience with a particular feature or functionality of a platform, they may be more likely to overlook its flaws or shortcomings. Conversely, if a user has a negative experience with a particular feature or functionality, they may be more critical of the entire platform, even if other features are well-designed and effective.
4. Centrality/central tendency bias
Centrality bias, also known as central tendency bias or the “average effect,” is a cognitive bias that occurs when we rely too heavily on central or typical pieces of information, rather than considering the full range of information available. This bias leads us to focus on information that falls within the center of distribution or range while ignoring information at the extremes. For example, if we are asked to rate a product or service on a scale of 1 to 10, we may be more likely to give it a score of 5 or 6, as these values are seen as typical or central, rather than considering the full range of scores available. Similarly, if we are asked to remember a list of items, we may be more likely to remember items that are in the middle of the list, rather than those at the beginning or end.
For example, if a user is asked to rate a feature or functionality of a platform, they may be more likely to give a score that falls within the middle of the scale, rather than considering the full range of scores available. This can lead to a skewed perception of the effectiveness or popularity of a feature.
5. Leniency bias
Leniency bias is a psychological phenomenon that describes the tendency of people to rate others more favorably than they deserve. This bias can occur in various contexts, such as performance evaluations, academic grading, or hiring decisions. Essentially, leniency bias means that the rater or evaluator is too kind or generous in their assessment, leading to inflated scores or ratings for the recipient. While leniency bias may seem harmless, it can have significant consequences for individuals or organizations. For example, if a manager consistently gives high ratings to underperforming employees, it can create a false sense of security and prevent the company from addressing the problem effectively. Likewise, if a teacher gives high grades to students who did not earn them, it can lead to overconfidence and lack of motivation to improve.
One reason why leniency bias occurs is that people tend to avoid conflict or confrontation. They may feel uncomfortable giving low ratings or negative feedback, especially if they have a personal relationship with the person being evaluated. Additionally, some raters may be more lenient than others due to their personality traits, beliefs, or culture. For instance, people from collectivist cultures may prioritize harmony and group cohesion over individual achievement, leading to more lenient evaluations.
6. Similar-to-me bias
Similar-to-me bias is a cognitive bias that describes the tendency of people to feel more positively towards others who share similar characteristics, such as background, interests, or beliefs. This bias can occur in a variety of situations, such as hiring decisions, team formation, or social interactions. Essentially, people prefer others who are like them and may unconsciously discriminate against those who are different. While similar-to-me bias may seem harmless or natural, it can have significant consequences for individuals and society. For example, if a hiring manager favors candidates who resemble them in terms of gender, race, or education, it can perpetuate existing inequalities and limit diversity and inclusion in the workplace. Likewise, if a teacher favors students who share their interests or style of learning, it can disadvantage other students and hinder their development.
One reason why similar-to-me bias occurs is that people tend to perceive those who are similar to them as more trustworthy, competent, and likable. This is because people naturally seek validation and affirmation from others, and seeing someone who shares their values or experiences can create a sense of familiarity and comfort. Additionally, people may be more likely to trust and cooperate with those who they perceive as part of their in-group, leading to a self-fulfilling prophecy of similarity.
7. Idiosyncratic rater bias
One reason why idiosyncratic rater bias occurs is that people have unique perspectives, beliefs, and experiences that shape their judgments and evaluations. This can include their personality traits, cognitive biases, or emotional states, which may influence their attention, memory, or interpretation of the target. Additionally, people may have different standards or criteria for evaluation, based on their expertise, preferences, or values, leading to inconsistencies or subjectivity in the process.
8. Confirmation bias
Confirmation bias is a cognitive bias that affects people’s decision-making skills, including my own. It refers to the tendency of individuals to seek out information that confirms their pre-existing beliefs, rather than looking at evidence that contradicts their views. In other words, we tend to interpret information in a way that validates our current opinions and ignore facts that do not align with our beliefs. I have personally experienced confirmation bias in my life, both in my personal and professional realms. Whenever I come across an argument or discussion that challenges my beliefs, I tend to ignore it or dismiss it as irrelevant. Instead, I search for information that aligns with my opinions and reaffirms my views.
For instance, I remember a time when I was discussing a political issue with a friend. We held different opinions, and as we were talking, my friend presented me with evidence that contradicted my perspective. Rather than considering the information and evaluating its validity, I immediately dismissed it as biased and irrelevant. I did not realize at the time that I was falling prey to confirmation bias.
9. Gender bias
Gender bias is a significant problem in today’s society. It is a form of prejudice that arises when people are treated differently based on their gender, which can be detrimental to individuals’ personal and professional lives.
For example, some words such as “he” or “she” are used to refer to a person of a specific gender, which can exclude or marginalize people who do not conform to traditional gender norms.
A language is a powerful tool that can shape our perceptions of the world, and gendered language can perpetuate harmful stereotypes and biases. In addition, gender bias can also affect the accuracy of my responses. For instance, if the data that I have been trained on contain biased or incomplete information, it can lead to biased responses. For example, if a dataset only contains data from male individuals, it could lead to inaccuracies in my responses when asked about topics that affect women.
10. Law of small numbers bias
Have you ever heard of the Law of Small Numbers Bias? It refers to the tendency of people to make assumptions about a large group based on small samples or experiences. In other words, we tend to generalize based on limited data, which can lead to flawed conclusions. I have experienced this bias in my own life, particularly in my early years of schooling. As a student, I often found myself judging entire subjects based on one or two bad experiences. If I didn’t do well on one math test, I would assume that I was bad at math altogether. If I struggled to understand one concept in science, I would write off the entire subject.
It wasn’t until I matured and gained more experience that I realized the danger of the Law of Small Numbers Bias. I began to see that one or two experiences could not accurately represent an entire subject or group of people. I learned that I needed to take a broader view, gather more data, and consider multiple perspectives before jumping to conclusions. This bias is not limited to students. It is prevalent in all areas of life, from politics to business to personal relationships. We see it in the media, where a single incident can be used to define an entire group of people. We see it in the workplace, where one employee’s behavior can be used to stereotype an entire department.
To overcome this bias, we must be willing to challenge our assumptions, seek out more information, and consider alternative perspectives. We must be open-minded and willing to admit when we are wrong. It takes effort, but the rewards are worth it. When we look beyond the small numbers, we gain a deeper understanding of the world around us and make better decisions. In conclusion, the Law of Small Numbers Bias can be a trap that limits our understanding and leads to flawed conclusions. By being aware of it and actively working to overcome it, we can broaden our perspectives and make better decisions.
