Most people prefer to work, socialize, and even relax in an environment that does not challenge or annoy them. In fact, unconsciously, people align their thinking with people, concepts, and thought processes that lead to an easy and comfortable situation or result. This tendency of individuals to favour those who are similar to themselves in terms of background, beliefs, or interests is called affinity bias. It is especially relevant in academia and research, where objectivity and impartiality are crucial. In this article, we will explain what affinity bias is and why it occurs. We will also present some expert tips on how to avoid affinity bias.
What is Affinity Bias?
Affinity bias, or similarity bias, is a concept that affects decision-making processes in various contexts, particularly in professional and academic settings. When an individual leans towards ideas, people, or groups with whom they share common ground, that individual is said to be displaying an affinity bias. In some cases, it may be an unconscious or unintentional bias caused by similarities in factors like age, socio-economic status, gender, social grouping, and educational or professional achievements.
In academia and research, when affinity bias sets in, it becomes challenging to ensure the objectivity and reliability of one’s research findings. In fact, it can lead to discrimination. To explain better, when we develop a strong preference for individuals who share similarities with us, and if our attachment to our own beliefs and opinions becomes so intense that those with differing perspectives provoke a strong adverse reaction, it can lead us to deviate from a rational and transparent way of thinking.
One could argue that working with a team that shares similar interests, is aware of each other’s likes and dislikes and is highly focused on what they want to achieve – is indeed the right approach. However, by surrounding yourself with only those who you like and agree with, you shut yourself off from possible new ideas and innovative perspectives. So, even if you feel the task that you had set out to complete has been successfully achieved, the reality would be that the results or findings would be compromised due to affinity bias.
To begin with, you would have sidelined or discriminated against specific individuals who do not share your ideas or with whom you may not be comfortable, even though they may be more qualified than those you ultimately selected for your team. Affinity bias has led to the denial of opportunities for people with better credentials and qualifications who, if selected, could have driven the research project differently, yielding optimal results and a more significant impact. Similarly, review panels that unintentionally favour proposals from researchers who share similar educational backgrounds or affiliations display affinity bias, which consequently limits funding opportunities for innovative projects led by smaller, underrepresented groups.
Affinity bias is an issue that is not limited to academia or research. It affects people across professions everywhere and can be seen in discussions and debates, in the day-to-day choices we make, in deciding whom to include in our friend circle, and even in mundane decisions like which movie to watch. It can manifest itself in various forms and approaches taken by individuals, institutions, and even in the policy choices of associations and governments.
Let us look at an example of affinity bias in an office setting where a senior manager is to be appointed by the governing body of an institution. Let us say that the governing body members are all men and in the age bracket of 45 to 50 years. The governing body instructs the human resources team to finalize candidates, preferably men who have considerable experience. As a result, the final shortlist of candidates for the post of senior manager will consist only of men. Consequently, this work opportunity is entirely closed to women, denying them a chance to prove themselves or to advance to senior positions.
At the same time, due to the undue reliance on much-needed experience, young and dynamic candidates are discriminated against who could have brought interesting new perspectives and could have taken the institution toward a new path of development and innovation. In other words, affinity bias can lead to exclusionary practices and hinder diversity.
It has been seen that affinity bias significantly impacts dynamics and relationships in workplaces and official settings, including decisions made regarding promotions, hiring, or even censures of staff and officials. Some of the ways to eliminate affinity bias in hiring decisions at institutions like universities or even private companies are by following inclusive attributes for postings in job vacancies as well as by having standardized selection procedures. To begin with, the selection panel itself can comprise people from multi-ethnic and diverse backgrounds; a blind resume selection process can be conducted where numbers classify applicants without disclosing names, gender or, ethnic or social groupings.
Avoiding affinity bias
As a first step toward avoiding bias, academic and professional institutions should conduct workshops or training sessions to create awareness about affinity bias and its implications. Students and researchers should be vigilant about avoiding affinity bias in their research. They should take proactive measures to eliminate affinity bias in research by involving and working with individuals from diverse backgrounds and differing perspectives. This will minimize the reliance on those with whom the researcher or student feels most comfortable with. Another way to avoid affinity bias would be to establish mentorship programs that connect underrepresented researchers with experienced professionals in their field. This support can help bridge gaps created by affinity bias.
Similarly, when it comes to academic publishing or grant applications, journal editors must consider using blind review processes where reviewers do not know the identities of authors or applicants. This will help reduce biases based on affiliation or background.
Affinity bias can adversely impact academic and research institutions by reducing diversity and inclusion among the students and faculty and negatively affecting the culture and ethos of educational institutions. It can also limit creativity and innovation and stifle breakthroughs in research and development by fostering insular thinking. That is why understanding what affinity bias is, why it occurs, and why it is problematic is essential for fostering fairness and inclusivity.
