A human mind is an extraordinary tool, but it’s not perfect. While we strive to base our decisions on logic, our thinking is constantly shaped by mental shortcuts.
We are all guided by unconscious (or implicit) bias, leading us to make assumptions about people without realising it. This can be damaging in all areas of life, but unconscious bias in the workplace is especially problematic for UK businesses.
Even with a commitment to diversity, equity, and inclusion (DE&I), unaddressed implicit bias can undermine fairness, hinder talent, and expose an organisation to legal risk.
Key Facts
- Unconscious bias in the workplace refers to stereotypes and assumptions about groups of people that individuals hold and act upon without conscious awareness.
- In the UK, nearly half (45%) of adults report having experienced some form of workplace discrimination, either during their employment or in the hiring process, according to a 2025 survey.
- Research from the Young Women’s Trust in 2024 found that discrimination experienced by racially minoritised young women at work has risen to 61%.
- Tackling bias is not just a legal requirement under the Equality Act 2010; achieving full representation for ethnic minorities could add £24 billion to the UK economy annually.

What is Unconscious Bias in the Workplace?
An unconscious bias is a belief or stereotype that we hold about groups of people that exist below our conscious thought.
We naturally pick up these stereotypes via our childhoods, societies, media representations, and life experience. And because they’re so deeply ingrained in our worldview, they can be difficult to recognise. This makes them arguably more damaging than conscious bias, which is easier to identify and eradicate.
But why do we have these biases in the first place? Unconscious bias is a type of mental shortcut our brains use to make decisions and make sense of the world.
Humans rely on mental shortcuts, or heuristics, all the time, and they’re often positive, or at least harmless.
For example, if there’s a long line outside the corner bagel shop, the mental shortcut tells us that they probably make delicious bagels. That’s a good heuristic that has no negative impact (except for other bagel shops).
Unconscious bias in the workplace, however, can be a harmful mental shortcut.
While the decisions of our unconscious minds can seem intuitive and thus correct, there are real-world, detrimental consequences to letting our unthinking impulses take over. They favour certain employees (particularly those from dominant groups) over others, which leads to greater inequality in the workplace.
Implicit bias is one explanation why, despite the best efforts of companies, the workplace can remain an unfair environment, potentially leading to breaches of the UK’s Equality Act 2010.
Types of Unconscious Bias: Gender Bias, Affinity Bias, And More
Under UK law, discrimination against individuals based on nine ‘protected characteristics’ is illegal. Unconscious bias often manifests in relation to these characteristics. Recognising the common forms of bias is the first step to mitigating them.
Racial Bias
Racial and ethnic bias remains one of the most insidious forms of discrimination. According to a 2025 report, over two-thirds (69%) of ethnic minority employees in the UK reported experiencing discrimination at work or during their job search. This can manifest as microaggressions, exclusion from networking opportunities, or being overlooked for promotion. In a 2026 analysis by the Joseph Rowntree Foundation, workers from Black, Pakistani, and Bangladeshi backgrounds were found to be disproportionately concentrated in insecure work.
Gender Bias
While progress has been made, significant disparities remain. According to the Office for National Statistics, the gender pay gap among all UK employees was 12.8% in April 2025. This bias can be subtle, such as judging female employees more harshly for assertive ‘masculine’ traits or assuming male employees are not primary caregivers.
LGBTQ+ Bias
Sexual orientation and gender reassignment are protected characteristics under the Equality Act 2010. Despite this, LGBTQ+ employees often face barriers to advancement and discrimination, such as being excluded from client-facing roles or dealing with homophobic comments.
Affinity Bias
Affinity bias is when we show an inclination towards people that are similar to us in some way. This could be a shared background, characteristics, hobbies, or anything else.
When selecting someone for a project, we may choose a person based on this bias rather than their experience or ability.
Name Bias
Name bias is when a person favours a particular type of name over another. This generally occurs during the hiring process.
For instance, UK-based research has shown that job applicants with ‘white-sounding names’ are significantly more likely to receive a positive response than those with names that suggest an ethnic minority background. This form of bias can illegally screen out qualified candidates before they are even assessed on merit.
Appearance Bias
Appearance bias refers to the preferential treatment of attractive and tall people over others.
The result in the workplace?
Tall employees earn around 10 – 15% more than shorter employees. Less conventionally attractive people are less likely to be hired and more likely to be fired. Bias related to an employee’s weight can also lead to unfair penalties and is a significant issue.
Conversely, being deemed too attractive is also a handicap. Rather than evaluating a person’s ability, we can assume they have succeeded in life because of their looks.
Age Bias
Age bias is when we make assumptions about a person based on their age.
For example, we may view an older employee as more resistant to technology or holding more “traditional” views. We may not take the opinions of young employees as seriously as more senior employees.
How Does Unconscious Bias Affect the Workplace?
There are ethical reasons to address unconscious bias.
In a quest to make the world fairer and more equal, we must eliminate the structures that systematically elevate certain people over others. But implicit bias has consequences for companies, too.
It Damages the Hiring Process
Left untreated, unconscious bias can significantly impact the hiring process and harm a company’s diversity objectives. It can also lead to a weaker workforce since recruiters assess candidates on criteria that have little to do with their ability to perform the job.
Impacts Morale and Employee Experience
An employee that experiences negative unconscious bias will be more likely to disengage from their work. They can feel alienated, be less likely to put their ideas forward, and have less prosperous relationships with colleagues.
A poor approach to DE&I directly impacts retention. Nearly half (45%) of adults have faced workplace discrimination, which severely damages morale and engagement.
It Wastes Employee Potential
The whole organization suffers when promotions are given based on bias rather than merit. By elevating certain employees over others, companies risk having less-able employees in senior positions.
So How to Tackle Unconscious Bias in the Workplace?
While it’s impossible to eliminate unconscious bias entirely, organisations can significantly reduce its influence. The advisory service Acas recommends a multi-faceted approach that focuses on systemic changes rather than relying solely on awareness training, which has shown limited evidence of changing behaviour long-term.
Look at Your Hiring Process
Implicit bias is especially influential during the hiring process.
As such, it’s important to find an approach that judges an applicant on their merits. Information such as their name or hometown should not be a factor. With recruitment software, you can standardise the hiring process. For example, you can create custom application forms that omit non-relevant information, and use structured interviews with consistent evaluation criteria for all candidates to ensure a fairer comparison. Blind sifting, as recommended by Acas, is another effective approach.
Create a Conversation
Learning about unconscious bias is the first step to overcoming it. We can’t move past something if we don’t know it exists. So start the conversation.
Ask employees about their experiences of negative bias within your company. Once you know the barriers holding your workforce back, you can plan training workshops to deal with those issues.
Change Your Performance Reviews
Performance reviews should fairly evaluate the performance of an employee. They analyze the past and direct the employee’s future and significantly impact their professional development.
The problem?
Unconscious bias can cloud these reviews, especially if just one person is in charge of the evaluations. Performance management software can help mitigate bias by introducing structured, multi-source feedback. A system that facilitates 360-degree appraisals ensures that input is gathered from peers and managers, providing a more balanced view than a single-manager evaluation. This data can also be analysed to spot patterns of potential bias across departments.
Conduct Ongoing Reviews
Unconscious bias is never far away. A one-time training session, while helpful, should only be the start.
Moving forward, companies should incorporate initiatives and targets that genuinely work to make the workplace more diverse and inclusive.
Overcoming Our Biases
All companies have a responsibility to move the world forward.
While it’s impossible to eliminate these deep-seated impulses for good, we can reduce unconscious bias in the workplace through awareness and initiatives.
In doing so, we can help shape a recruitment process and working environment that’s fairer and more equal. And who knows what that could lead to for the employee, employer, and society at large?
FAQs
What is an unconscious bias?
An unconscious bias is a stereotype or belief about a group of people that exists below our conscious thought. These mental shortcuts are formed from our life experiences and societal influences, helping our brains make quick decisions, but they can often be harmful and inaccurate in a professional setting.
What is an example of unconscious bias in the workplace?
An example is affinity bias, where a manager might favour an employee who shares a similar background or hobby when assigning a desirable project, overlooking another colleague who is more qualified. This preference is often unintentional but can limit opportunities for others and lead to a less diverse team.
