Are unacknowledged biases undermining effective leadership?

Once we establish a strong belief or a point of view about something, it can be surprisingly difficult to let go of. Our idea of “the truth” embeds itself over time, and leads to us getting stuck in our ways.

Confirmation bias is one reason for this. As humans, we tend to notice, interpret, and remember information in ways that supports what we already believe, while overlooking evidence that challenges our assumptions. Over time, our interpretation of a situation can become so familiar that we stop questioning whether it is accurate.

These patterns influence how we see other people, how we make decisions, and even how we assess our own potential. For leaders, the consequences are major, and can shape everything from recruitment and promotion, to the ambitions people feel able to pursue. So what do we do about it?

 

How our beliefs become truth

Confirmation bias often develops through a series of initially reasonable judgements. For example, we might imagine that only people with a background in finance are suitable for a particular role within an organisation.

Next, we start noticing some evidence that supports the belief. For example, we see that a colleague who previously worked in finance is promoted. We might assume that the finance background was the deciding factor, while overlooking all the other factors that actually contributed to the appointment. This view is reinforced when we see that another colleague, who doesn’t have a background in finance, missed out on promotion.

As similar situations accumulate, we interpret them through the same lens. Evidence that supports our beliefs stands out, while alternative explanations become easier to dismiss. Before long, initial assumptions have hardened into what we see as established truth.

The consequences of these entrenched biases can spiral. For example, if I believe that a lack of financial experience rules me out of promotion, I may never put myself forward for the role, even if I have the capabilities and results to succeed. My belief has created a ceiling on my own ambition.

 

Context is decisive

Another important influence is unconscious bias. These are the automatic associations and assumptions that can affect our judgement without us even realising.

Because these assumptions can influence how we evaluate people from different backgrounds, unconscious bias is often discussed in the context of diversity and inclusion, and understandably so. But its implications reach much further into leadership and organisational performance. Every leader brings assumptions to the situations they face, and those assumptions help shape the context in which decisions are made.

Our context is decisive. The way we interpret a situation influences the options we see, the actions we consider reasonable, and the outcomes we believe are possible. Consider someone who has come to believe that technology is the domain of younger people. When an opportunity arises to take on a role involving AI, for example, they may assume they lack the aptitude and decide against applying.

The same dynamic plays out in organisations. A leader who assumes a particular team lacks the capability to deliver a challenging project may never give them the opportunity to demonstrate otherwise. When that team subsequently has limited experience of delivering ambitious work, the original assumption appears justified.

In both cases, the context reinforces the bias, and the bias further shapes the context. Unless someone recognises the pattern and intervenes, the same limitations can persist for years.

 

Bringing bias into the open

Beyond just recognising bias, it’s important to really interrogate how our assumptions might be influencing everyday decisions. One practical step is to become more deliberate about the evidence behind a judgement. When making a decision about a person, a team, or a business challenge, ask what you actually know, what you are assuming, and what alternative explanations might exist. Are you evaluating the available evidence, or selecting the parts that support a conclusion you have already reached?

It is also worth examining patterns over time. For example, who tends to receive the biggest opportunities? Whose ideas are taken seriously? Which teams are trusted with ambitious challenges, and which are repeatedly overlooked? Looking at decisions collectively can reveal assumptions that are difficult to spot in individual cases.

It’s also important to create the conditions for thinking to be challenged. If people feel unable to question a decision or offer a different perspective, assumptions can become embedded in organisational culture without ever being properly examined.

It goes without saying that experience and instinct are still essential in decision-making, but the challenge is to recognise when experience is just cementing our views, or when instinct is being treated as evidence without sufficient scrutiny.

The biases we carry influence how we interpret the world, but they can also influence the world we create. As leaders, we have a responsibility to recognise where our assumptions are narrowing the possibilities available to ourselves and others.
