Affinity bias is an unconscious preference for people who feel familiar, such as those with similar backgrounds, interests or experiences.
What is affinity bias?
Affinity bias happens when we naturally gravitate toward people who remind us of ourselves. It can show up in everyday workplace decisions — who gets listened to, who gets supported and who is seen as a ‘good fit.’
Because it’s often unconscious, affinity bias can influence hiring, promotions and feedback even when people are trying to be fair. Over time, it can make it harder to build inclusive teams and can limit the range of perspectives in a group.
The first step to reducing affinity bias is recognising it, then putting clear, consistent decision-making practices in place.

FAQs
How does affinity bias show up at work?
It can influence everyday decisions, such as who gets hired, who is seen as a ‘good fit’ and who gets development opportunities.
Why does affinity bias matter?
Even when unintentional, it can lead to unfair outcomes and make it harder to build inclusive teams.
Is affinity bias the same as unconscious bias?
Affinity bias is one type of unconscious bias. Unconscious bias is a broader term for attitudes or assumptions that can affect decisions without us realising.
How can organisations reduce affinity bias?
Using clear criteria and consistent processes can help people make more objective decisions. Awareness training can also help teams spot patterns and adjust.
Is affinity bias always intentional?
No. It’s often unconscious, which is why it can be difficult to recognise without taking a step back.
