How Hidden Assumptions Shape What We Perceive
We rarely experience an assumption as an assumption.
Once accepted, it tends to disappear.
We stop noticing the assumption…
and begin seeing through it.
This matters because assumptions do more than influence what we think.
They can influence what becomes available to perceive in the first place.
Assumptions Make the World Easier to Navigate
Assumptions are not inherently a problem.
In fact, ordinary life would be extraordinarily difficult without them.
We assume the floor will support us.
We assume familiar words will continue to mean approximately what they meant yesterday.
We assume the people around us will behave within some range of expected possibilities.
We assume countless regularities without consciously evaluating them.
This allows us to navigate without reconstructing reality every moment.
Assumptions reduce complexity.
And most of the time, that is useful.
The Useful Assumption Can Become Invisible
The difficulty begins when we forget that an assumption is an assumption.
Consider a simple statement:
“There are two choices.”
Once accepted, attention naturally moves toward evaluating the two choices.
Which is better?
Which is safer?
Which is correct?
Which should I choose?
But another question has quietly disappeared:
Are there actually only two choices?
The assumption did not merely influence the answer.
It helped determine which answers could appear.
What We Expect Changes What We Notice
Suppose two people enter the same meeting.
One expects resistance.
The other expects collaboration.
The same comment may be heard very differently.
A question may sound like a challenge to one person and curiosity to another.
A pause may look like opposition to one and consideration to another.
A disagreement may appear threatening or useful.
Neither person needs to consciously distort what happened.
Their assumptions may simply organize attention differently.
What they expect helps determine what becomes significant.
Assumptions Can Remove Possibilities Before We Decide
We often think of decision-making as choosing among possibilities.
But before we choose, something else has already happened.
Some possibilities became available for consideration.
Others did not.
This means assumptions can influence decisions long before conscious deliberation begins.
If I assume a problem has two solutions, I compare two solutions.
If I assume a person’s behavior has one obvious cause, I search within that explanation.
If I assume success must look a particular way, other forms of success may become difficult to recognize.
The decision may be perfectly rational…
within the world created by the assumption.
The Frame Often Arrives Before the Problem
Questions themselves can contain assumptions.
“How do we get employees to accept this change?”
That question may already assume:
- the change is correct,
- acceptance is the problem,
- employees are resisting,
- and management’s task is to overcome that resistance.
Perhaps all of those assumptions are accurate.
But perhaps they are not.
Compare the question with:
“What is happening in the relationship between the organization and this change?”
The second question does not guarantee a better answer.
It simply preserves more possibilities long enough to examine them.
This Is Why Four Possibilities Can Reveal What Two Conceal
Binary distinctions are extraordinarily useful.
Yes or no.
True or false.
Success or failure.
For or against.
Sometimes reality fits them well.
But when the distinction itself is assumed rather than examined, it can become interference.
A situation may contain a third possibility.
Or a fourth.
Something may be both.
Something may be neither.
Something may change depending upon the relationship from which it is observed.
Adding possibilities does not necessarily make perception less precise.
Sometimes it reveals the structure that premature reduction concealed.
Expertise Can Create Assumptions Too
Experience helps us recognize patterns quickly.
That is one of its great advantages.
But experience can also make familiar interpretations automatic.
An expert may recognize something a beginner cannot see.
The same expert may also stop looking at possibilities that experience has taught them to dismiss.
Expertise therefore creates an interesting tension.
It can expand recognition…
while simultaneously narrowing exploration.
The issue is not expertise.
The issue is whether the conclusions produced by expertise remain available for examination.
Assumptions and Recognition
Recognition often occurs when an assumption becomes visible.
Suddenly we notice:
“I thought those were the only choices.”
“I assumed that was what they meant.”
“I never considered another explanation.”
“I thought it had to happen that way.”
The external situation may not have changed at all.
What changed was the structure through which it was being perceived.
This is one reason recognition can occur before understanding. A relationship can become visible before we have fully explained its implications.
This process is explored further in Why Recognition Often Comes Before Understanding.
Assumptions Can Become Interference
An assumption does not need to be false to interfere.
It only needs to prevent something relevant from becoming available to recognize.
A useful assumption in one situation may become restrictive in another.
A successful model from yesterday may obscure something different happening today.
A value that normally provides direction may prevent consideration of an unfamiliar possibility.
A goal may focus attention so effectively that information outside the goal becomes invisible.
This is why interference can be difficult to identify.
It often arrives disguised as something useful.
The broader relationship between interference and perception is explored in How Interference Changes What We Are Able to See.
The decision may be perfectly rational within the world created by the assumption.
Hidden Assumptions in Leadership
Organizations accumulate assumptions.
About customers.
About competitors.
About employees.
About what is possible.
About what has always worked.
Eventually some of these assumptions become so familiar that they no longer appear to be assumptions.
They become “how things are.”
This can create a peculiar organizational problem.
A company may have access to all the information necessary to recognize a change…
while its existing assumptions prevent the change from becoming visible.
The Executive Insights collection and Executive Field Notes explore many of these questions from the perspective of leadership, organizations, and decision-making.
Hidden Assumptions in Everyday Language
Some assumptions are so deeply embedded that they appear in ordinary language.
We say someone has confidence.
Someone lacks courage.
Someone acquires wisdom.
Someone is filled with fear.
The phrases are perfectly ordinary.
But each quietly proposes a relationship between a person and an abstract quality.
Confidence becomes something possessed.
Courage becomes something absent.
Wisdom becomes something acquired.
Fear becomes something that fills a container.
Language does not prove that these relationships are real.
But it can make them extraordinarily easy to assume.
The Freedom Series uses brief questions to make some of these unnoticed assumptions visible again.
Questioning an Assumption Does Not Mean Rejecting It
This distinction is important.
To examine an assumption is not to declare it wrong.
The assumption may turn out to be useful.
It may even be the best available model.
But once an assumption becomes visible, something changes.
It becomes possible to compare it.
To test it.
To temporarily set it aside.
To consider what becomes visible without it.
That creates another degree of navigability.
An assumption does not need to be false to interfere.
A Simple Experiment
The next time something appears completely obvious, consider asking:
What would have to be assumed for this to appear obvious?
You do not need to reject the answer.
You do not need to replace it.
Simply make the assumption visible.
Then look again.
You may see exactly what you saw before.
Or you may discover something that the assumption had quietly removed from view.
