Predictions Versus Reality: How Assumptions Distort Our Image

A prediction is not a fact. But once you start treating it as one, it influences what you notice, how you behave and which possibilities you stop seeing. Sometimes the future you feared appears to prove you right, while your own prediction quietly helped to create it.

If I walk down my street, turn left and then turn right after about a hundred metres, I will find a supermarket where I can buy milk and bread. I cannot see the supermarket from where I am writing this. I cannot be completely certain it is open. There could have been an accident, a power failure or some other unexpected event. It may even have closed permanently without me knowing.

Still, my prediction is probably correct. I have walked that route many times. The supermarket was there yesterday and nothing has given me reason to believe that it will be gone today.

We make predictions like this continuously. We expect the car to start when we turn the key. We assume our clothes are still hanging where we left them. We believe a colleague will respond in roughly the same way as before. Without this ability, ordinary life would require an exhausting amount of conscious thought.

The problem is not that we make predictions. The problem begins when we forget that they are predictions.

Your Mind Does Not Wait for Reality

Our minds constantly use earlier experiences to anticipate what will happen next. Theories of predictive processing even describe perception as an ongoing interaction between what the brain expects and the information it receives. Cognitive scientist Andy Clark explored this idea in his paper Whatever Next? Predictive Brains, Situated Agents, and the Future of Cognitive Science.

You do not need to understand neuroscience to recognise the process. A customer has not replied for three days and you think the proposal has been rejected. Your partner is quieter than usual and you assume something is wrong between you. A member of your team questions a decision and you conclude that the person is resistant to change.

Perhaps you are right. That is always possible.

But it is also possible that the customer is busy, your partner is tired and your employee sees a problem you have missed. Reality has not yet provided the answer, but your mind dislikes the open space and fills it with a story.

That story is shaped by what you have experienced before, but also by what you fear, hope and believe about yourself and other people. The prediction may feel completely convincing because the emotion attached to it is real. Yet a real emotion does not automatically make the prediction accurate.

The Difference Is Not Between Facts and Assumptions

I used to describe some predictions as fact-based and others as assumption-based. That distinction is too simple. Every prediction contains assumptions because the future has not happened yet.

The real difference is the quality of the evidence and the certainty with which we hold the conclusion.

My expectation that the supermarket is still there is supported by repeated experience and can easily be tested. The thought that no employer will ever hire you after ten rejections is built on much less evidence, even though those rejections may have been genuinely painful. The statement does not describe what happened. It turns what happened into a conclusion about the entire future.

Words such as always, never, everyone and no one often reveal that shift. One failed business idea becomes proof that you are not an entrepreneur. One dishonest partner becomes evidence that nobody can be trusted. One difficult employee convinces a leader that people only perform when they are controlled.

Past experience deserves to be taken seriously. It can teach you, protect you and help you recognise patterns. But experience becomes a prison when you no longer allow reality to show you anything new.

A Prediction Can Close the Future Before It Arrives

One of my brothers was over fifty when he found himself without work. Earlier in life, he had taken care of his children because his then-wife had a good job. As a result, his CV did not look like the CV of someone who had followed a conventional career path.

Finding work was difficult. After ten rejections, he stopped applying because, as he put it, nobody would hire someone like him.

I understood why he felt that way. Ten rejections are not imaginary and disappointment becomes heavier when every new application asks you to risk another one. But “I have been rejected ten times” and “nobody will ever hire me” are not the same statement.

The first describes experience. The second predicts the future.

Once he accepted that prediction as reality, he no longer needed an eleventh employer to reject him. He did it on their behalf.

This is how assumptions can become self-reinforcing. You expect rejection, so you stop approaching people. You expect a disagreement, so you enter the conversation defensively or avoid it altogether. You believe an employee cannot be trusted, so you control every detail until that employee stops taking initiative. The behaviour that follows from the prediction helps to create an outcome that appears to confirm it.

That does not mean every disappointing outcome is self-created. Companies reject qualified people. Relationships really do become unsafe. Employees can be unwilling to take responsibility. The point is not that reality is always better than you fear. The point is that you should not decide what reality is before you have allowed it to answer.

Positive Predictions Are Not Facts Either

Negative expectations are not the only predictions capable of shaping our behaviour. Confidence and hope also influence which actions we take and how long we remain open to possibility.

When I started my advertising agency at 21, the visible facts were hardly reassuring. I had personal debt, little work and more costs than income. Yet I believed clients would eventually come. That belief made me rent an office, present the company as something that was moving forward and continue long enough for people around us to gain confidence and recommend us.

The growth did not happen at the speed the finances required. There were moments when the agency was technically close to failure. Still, I remained convinced that opportunities would come. Eventually MyCom became a client, followed by our first assignment for Samsung. The agency later grew internationally.

That story does not prove that confidence magically creates success. If those clients had not arrived, the same belief could have ended in failure. A positive prediction is still not a fact.

What it does show is that predictions influence behaviour. The prediction that nobody would come would have made me close the door. The belief that somebody might come kept me creating time, visibility and possibilities. As I wrote in How to Keep Going When Your Business Is Struggling Without Lying to Yourself, confidence does not remove reality. It determines how much possibility you can still see within it.

We therefore should not replace negative certainty with positive certainty. Telling yourself that everything will definitely work out can be just as disconnected from reality as deciding that nothing ever will.

The healthier position is more demanding:

I do not know what will happen, but I will not close a possibility before reality does.

Leaders Often Find What They Expect to Find

Predictions become especially powerful when you have authority over other people.

Imagine that a new manager sees an employee miss a deadline and concludes that the employee lacks commitment. From that moment, the manager starts noticing every delay, short answer and moment of hesitation. Work that goes well receives less attention because it does not fit the prediction.

The employee senses the distrust and becomes more careful. Ideas are kept to themselves because every mistake seems to carry extra meaning. Initiative decreases. The manager now sees even more evidence of disengagement and feels proven right.

Perhaps the employee really was disengaged. But perhaps the manager's early prediction changed the relationship before either person understood what was happening.

This is why leaders must be careful with conclusions that sound like observations. “She is resistant.” “He has no ambition.” “They cannot handle responsibility.” These statements may contain useful information, but they can also be stories built from a small number of events.

A leader who believes the story too quickly stops asking questions. Instead of discovering what prevents movement, the leader starts managing the person they have predicted rather than the person actually in front of them.

This does not mean leaders should ignore patterns or avoid difficult decisions. It means they should remain capable of being surprised. Authority makes your assumptions more consequential because other people have to live inside the reality you create from them.

Assumptions Also Change Relationships

The same process appears in personal relationships. Someone has been betrayed before and becomes alert to every possible sign of dishonesty. A delayed message feels like rejection. A forgotten detail becomes proof that the other person does not care. A harmless mistake begins to look intentional.

Again, the fear did not come from nowhere. It may have been learned through painful experience. But protecting yourself from the past can make it impossible for someone new to behave differently.

The other person eventually becomes exhausted from having to disprove a prediction they did not create. They withdraw, become defensive or stop explaining themselves. The distance that follows then seems to confirm the original belief that people cannot be trusted.

When emotions take over, it becomes difficult to distinguish what happened from the meaning we gave it. That distinction is explored more deeply in How to Reframe Your Thoughts When Emotions Take Over. Your feelings should not be dismissed, but neither should every conclusion produced by those feelings be treated as evidence.

How Do You Recognise a Prediction Disguised as Reality?

The clearest sign is not that the prediction is negative. It is that you have stopped experiencing it as a possibility and started speaking about it as a certainty.

You no longer think, “I am afraid this proposal may be rejected.” You think, “They are not interested.” You do not say, “I worry that I may not find another relationship.” You say, “There are no good people left.” You stop saying, “This employee has resisted two changes.” You say, “This person will never change.”

The prediction becomes part of how you see the world, and everything you notice is organised around it.

Low self-worth can make this even more convincing. If you already believe that you are not good enough, every setback appears to confirm something fundamental about who you are. A rejected application no longer means that one employer chose someone else. It means that you are unemployable. A relationship ending no longer means that two people could not continue together. It means that you are unlovable. I explore that difference further in Building Self-Confidence by Strengthening Self-Worth.

The event may be real. The identity you build from it is still an interpretation.

Four Questions That Reopen Reality

You do not need to distrust every instinct or analyse every ordinary expectation. Most predictions are useful and many are accurate. The goal is to notice the predictions that limit important choices, relationships or opportunities before they have been properly tested.

What do I actually know?

Describe only what has happened. The client has not replied for three days. You received ten rejections. One employee missed a deadline. Your partner cancelled dinner.

This may already be disappointing or painful. There is no need to make it smaller. But keep the fact separate from the future your mind has built around it.

What am I adding?

Listen for the conclusion. They are not interested. Nobody will hire me. The employee does not care. My partner is losing interest.

Then ask whether that conclusion is supported by evidence or whether it is an attempt to remove uncertainty. Certainty can feel safer than not knowing, even when the certainty is painful.

What else could be true?

Do not force yourself to invent a cheerful explanation. Look for plausible alternatives. The customer may be busy. Your experience may fit a different kind of employer. The employee may not understand the purpose of the task. Your partner may be dealing with something that has nothing to do with you.

You are not trying to replace one certainty with another. You are reopening reality.

Which action keeps the possibility open?

Send a respectful follow-up. Submit another application. Ask the employee what happened. Have the conversation you are tempted to avoid.

The best next step is often not the one that guarantees the desired outcome. Such guarantees rarely exist. It is the action that allows new information to enter the situation.

Let Reality Have the Final Word

Experience matters. Intuition matters. Emotions matter. They all help us anticipate what may happen and protect us from repeating the same mistakes.

But none of them can see the future.

The danger begins when a prediction becomes so convincing that we stop testing it. We withdraw, control, avoid, reject or give up, and then call the result reality.

Sometimes your fear will prove justified. Sometimes your confidence will prove misplaced. Being open to reality does not guarantee a pleasant answer.

It gives you something more important: the chance to respond to what is actually happening instead of living inside a future your assumptions created for you.

Do not believe every prediction simply because it sounds like your own voice.

Let reality answer first.
