Biased Decision Making: 3 Signs Bias May Be Affecting Your Decisions

AReaWe all like to believe we make rational decisions. We consider the information, weigh the options and choose the best course of action.

Except human judgement does not work quite that neatly. Our decisions can be shaped by existing beliefs, first impressions, emotions, previous experiences, assumptions about other people and the information that happens to reach us first.

That does not mean we are bad decision makers. It means we are human.

Bias becomes a problem when influences we have not properly examined begin to affect how we interpret evidence, evaluate people or choose between competing options.

At work, that can affect recruitment, promotion, performance decisions, budgets, strategy, investment, customer relationships and everyday leadership.

The goal is not to become completely unbiased. That is unrealistic.

The goal is to become better at recognising when bias may be affecting judgement and to use processes that help us make more balanced decisions.

What is a biased decision?

A biased decision is one in which information is not being considered evenly. Existing beliefs, preferences, assumptions or other influences may cause us to give some evidence too much weight and other evidence too little.

A biased decision is not simply a decision somebody else disagrees with. Two thoughtful people can examine the same evidence and reach different conclusions.

The concern arises when judgement is being distorted by factors that are not sufficiently relevant to the decision.

For example:

• A manager decides an employee is not ready for promotion because they do not “look like a leader”.
• A recruitment panel becomes attached to the first strong candidate and judges everyone else against them.
• A leadership team approves an initiative because everybody searches for evidence supporting the idea while ignoring evidence that challenges it.
• A manager continues to see an employee as a poor performer because of an old mistake despite substantial evidence that their performance has changed.

These are not necessarily deliberate acts. Bias often operates precisely because it feels like ordinary judgement.

Three signs that bias may be affecting your decisions

1. You keep finding evidence that proves you are right

This is one of the clearest warning signs. Confirmation bias describes our tendency to seek, interpret or remember information in ways that support what we already believe.

Once we form a view, it can become surprisingly easy to find evidence for it. Imagine a manager believes one of their employees lacks initiative.

They notice every occasion when the employee asks for direction. They may pay much less attention to the occasions when that person acts independently, solves a problem or takes ownership without prompting.

The evidence has not disappeared. The manager is simply giving different evidence different weight. The same thing can happen with strategy.

A leadership team becomes excited about a new project. Research begins. The team finds customer comments, market reports and competitor activity that support the proposal.

Information that challenges the opportunity is explained away. Before long, the organisation feels it has accumulated substantial evidence.

It may have accumulated substantial supporting evidence.

Those are not always the same thing.

What can you do?

Ask:

What evidence would cause me to change my mind?

If the answer is “nothing”, you are no longer testing an idea. You are defending it. Actively look for disconfirming evidence. Ask somebody who disagrees with you to explain their reasoning. Consider the strongest case against your preferred option.

Look for information you would rather not find.

Good decision making requires more than proving your first idea was right. It requires giving yourself a genuine opportunity to discover that it might be wrong.

2. You are judging the person before you have examined the evidence

Bias can also appear when assumptions about people begin to substitute for evidence. Stereotypes are broad assumptions applied to individuals because they are perceived as belonging to a particular group.

Other assumptions may be less obvious.

• Someone appears confident, so we assume they are competent.
• Someone is quiet, so we assume they lack leadership potential.
• Someone reminds us of a previous high performer, so we expect similar capability.
• Someone does not fit our picture of the “right type of person”, so we become more critical of their experience.

These judgements can happen quickly. The risk is that we then interpret subsequent information through the lens of the first impression.

This is particularly important in recruitment, succession planning and performance evaluation.

Consider the phrase: “They’re just not a culture fit.”

Sometimes that describes a genuine mismatch.

Sometimes it means: “They are different from the people I am used to.”

What can you do?

Define your criteria before evaluating the person. What evidence actually matters? What capabilities are required? What behaviours are relevant? Which criteria are essential and which are merely preferences?

Then assess people against those criteria as consistently as possible.

For recruitment, this may mean asking candidates comparable questions, using agreed scoring criteria and separating observations from impressions.

For promotion decisions, it may mean defining what readiness looks like before discussing individual names. For performance decisions, it means distinguishing:

What have I observed? from: What have I concluded?

That small distinction can materially improve the quality of the conversation.

3. The first information you received is still doing too much work

Another common source of bias is anchoring. An anchor is an initial piece of information that becomes a reference point for later judgement.

• The first budget estimate.
• The first salary figure.
• The first forecast.
• The first candidate interviewed.
• The first explanation you hear after something goes wrong.
• The first opinion expressed in a meeting.

Once an anchor exists, later decisions can remain closer to it than the evidence warrants.

Imagine an initial project estimate is £/$100,000.

New information later suggests the work could cost substantially more.

Discussions often begin with: “How much above £100,000 will this be?”

The first estimate has already shaped the frame.

A better question might be: “If we were estimating this project today, with everything we now know, what would we expect it to cost?”

That creates room for a genuinely new judgement.

What can you do?

Where possible, make independent estimates before seeing somebody else’s answer. Ask people to record their view before the group discussion begins.

Use ranges rather than a single early number when uncertainty is high.

Revisit important decisions when material new information becomes available.

And ask: If I had not seen the original information, what conclusion would I reach now?

Feelings can influence decisions, but removing emotion is not the answer

Emotion and judgement are closely connected. How we feel about an option, person or outcome can influence how risky, attractive or credible it appears.

Decision researchers sometimes describe this through the affect heuristic, where our positive or negative feelings about something influence subsequent judgements.

But this does not mean good decision making requires becoming emotionless. Emotion can also contain useful information. Concern may signal that a risk deserves attention. Discomfort may indicate unresolved conflict.

Enthusiasm may reflect genuine opportunity. Empathy may provide important information about the consequences of a decision for other people.

The challenge is recognising when feelings are informing judgement and when they are driving it without enough scrutiny.

Good judgement creates enough distance to ask:

• What am I feeling?
• What evidence do I have?
• What assumptions am I making?
• Would I reach the same conclusion if I felt differently about this person or situation?

The aim is perspective, not emotional detachment.

Why knowing about bias is not enough

Learning the names of cognitive biases can be useful. It can also create false confidence. We may become very good at spotting bias in everybody else.

The harder task is recognising it in ourselves.

Research on decision making suggests that awareness alone does not reliably remove bias. A more practical approach is to improve the process through which important decisions are made.

That shifts the question from:

“Am I biased?” to: “What have we built into this decision that helps us test our judgement?”

Seven practical ways to reduce bias in workplace decisions

Separate facts from interpretation

Write down what you actually know. Then separately record what you think it means.

For example:

Fact: Three customer complaints were received this month.

Interpretation: Service quality is deteriorating.

The interpretation may be correct. But keeping the two separate makes the assumption visible and testable.

Define the criteria before choosing

Agree what matters before discussing the preferred option. This is particularly useful in recruitment, promotion, investment and supplier decisions.

Changing the criteria after seeing the candidates or options makes it much easier to justify the outcome we already prefer.

Seek disconfirming evidence

Ask what would prove the proposal wrong. Look for information that challenges the favoured position. Invite somebody to make the strongest credible case against it.

Challenge is most useful before the decision is made, not six months later when everybody is explaining what went wrong.

Gather independent views before group discussion

The first confident speaker in a meeting can become an anchor for the group. For significant decisions, ask people to form or record an initial judgement independently before hearing everybody else’s view.

Then compare the reasoning. This can expose disagreement that might otherwise disappear through conformity.

Slow down important decisions

Not every decision needs more analysis. Some genuinely need speed.

But when a decision is difficult to reverse, expensive, strategically important or highly consequential for people, deliberate thinking is usually worth the time.

A pause can interrupt automatic judgement.

Ask what has changed

Past experience matters. It can also become an anchor.

When revisiting an existing decision, ask:

• What information is new?
• Which assumptions no longer hold?
• What would we decide if this situation appeared for the first time today?

Record the reasoning

For important decisions, capture the assumptions, evidence and reasoning behind the choice.

This creates a useful record later. Did the outcome differ because the decision was poor? Because the assumptions changed? Because something genuinely unpredictable occurred?

Without a record, hindsight makes everything look more obvious than it was.

Good decision making is not only an individual capability

Bias is often discussed as if it exists entirely inside one person’s head. Organisations can also build systems that make balanced judgement easier or harder.

A manager may be trying very hard to make a fair decision while working with vague criteria, incomplete information, unclear authority and pressure to act quickly.

That is not only a personal problem. It is a system problem.

At flowprofiler®, we often look at both the person and the environment in which behaviour occurs.

One practical way to do that is through the Triple A Framework.

Aptitude

Do we have the knowledge and capability required to make this decision? Does the person understand the issue? Do we have access to relevant expertise?

Attitude

Are we genuinely willing to question our own assumptions? Can we change our minds when better evidence appears? Are we protecting the quality of the decision, or protecting our ego and preferred position?

Approach

Are we using a decision process appropriate to the situation? Have we tested alternatives? Have we heard different perspectives? Have we separated evidence from interpretation?

The environment matters too.

Our Enabling Four provide another useful check.

Rules

Are the decision criteria, standards and boundaries clear?

Roles

Is it clear who should contribute, advise and decide?

Responsibilities

Does somebody own the quality of the evidence, the challenge process and the final decision?

Resources

Do people have sufficient information, expertise and time to make the decision well?

Better judgement comes from capable people working within effective systems.

What does Unbiased Thinking mean in flowprofiler®?

Unbiased Thinking is one of the six resilience dimensions measured by resilienceflow®. The name does not imply that anybody can remove all cognitive bias.

Nor does resilienceflow® diagnose confirmation bias, implicit bias or any other psychological condition. Unbiased Thinking examines a workplace behavioural pattern.

At an effective level, it can involve creating enough distance from immediate feelings or personal involvement to consider evidence calmly and reach a coherent judgement.

It can support behaviours such as:

• examining facts before reaching conclusions
• stepping back from emotionally charged situations
• considering alternative explanations
• remaining measured when personally invested
• and allowing new evidence to change an existing view.

But, as with every flowprofiler® dimension, more is not automatically better.

When Unbiased Thinking is underused

A person may reach conclusions too quickly. Immediate feelings or personal involvement may shape judgement. It may be harder to step back when an issue feels threatening or important.

When Unbiased Thinking is in flow

The person can create sufficient distance to examine the evidence without losing sight of the situation. They can remain measured, consider alternatives and make decisions that are proportionate to the information available.

When Unbiased Thinking is overused

Objectivity can turn into detachment. Analysis can become excessively clinical. Emotional, relational or contextual information may be dismissed because it does not look sufficiently rational.

The strongest decision is not always the one with the least emotion. It is the one in which relevant information has been considered in proportion.

Bias can become more visible under pressure

People do not necessarily make decisions in exactly the same way in every situation. Pressure changes context. Time becomes shorter. Consequences feel greater. Emotion may increase.

We may become more certain, more defensive, more cautious or more attached to familiar solutions.

flowprofiler® assessments examine behaviour in two states: day to day and under pressure.

That distinction matters because somebody may approach routine decisions thoughtfully but find it much harder to create distance when personally invested or under significant pressure.

The reverse is also possible.

Some people become so analytical under pressure that they lose important human and contextual information. Understanding the shift can be more useful than simply labelling somebody a “biased decision maker”.

Behaviour is contextual. And behaviour can change.

A simple bias check before an important decision

Before committing to a significant decision, ask yourself:

• What do I currently believe?
• What evidence supports that belief?
• What evidence challenges it?
• Which facts am I giving the most weight to, and why?
• Am I evaluating the evidence or the person presenting it?
• What assumptions have I made?
• What was the first information I received?
• Whose perspective is missing?
• What would make me change my mind?
• If I were wrong, what would I wish I had checked?

You may still reach exactly the same decision. But you will have tested it more thoroughly.

Better decisions begin with better questions

Bias is part of human judgement. Trying to eliminate it completely is unlikely to be productive.

Building the capability to notice it, question it and design better decision processes around it is much more useful.

That means challenging assumptions.

Seeking evidence that does not agree with you.

Creating space between emotion and action.

Listening to people who see the situation differently.

And recognising when your decision process needs more structure.

The objective is not perfect objectivity.

It is better judgement.
