Perspectives No. 10: Assumptions vs. Expectations by Anna Osadchyy, exploring how assumptions and expectations shape judgment and decision-making.

There are moments when our response to something seems entirely explained by what happened.


A decision was made differently than anticipated. Someone whose judgment we trusted failed to see something that seemed obvious. A conversation revealed an understanding we did not know was different from our own.


The disappointment, frustration, concern, or quiet loss of confidence that follows can feel self-explanatory.


Something happened. We responded to it.


Except between an event and our response to it, there is often an invisible reference point: some version of what we believed would, should, or could reasonably have been expected to happen instead.


And beneath that expectation may be something even less visible.


An assumption about what was already understood. What another person knew. What a role required. What competence, loyalty, judgment, care, respect, or responsibility should look like without anyone having to explain it.


By the time reality contradicts any of this, the assumption itself may have disappeared almost entirely.


We see what happened.


We see what it appears to mean.


What we may no longer see is everything we had already accepted as true before either occurred.



The Difference Between an Assumption and an Expectation


Assumptions and expectations occupy different places in our understanding.


An assumption is something we have accepted as true without necessarily establishing that it is.


An expectation extends that understanding forward. It is what we anticipate will happen because of what we believe to be true.


We expect a senior executive to recognize when a problem warrants escalation because we carry some prior understanding of what seniority should entail.


We expect a business partner to consult us before making a consequential decision because we already hold some understanding of what partnership means.


The expectation is relatively easy to see. The premise beneath it often is not.


An assumption describes the reality we believe we are already standing in. An expectation extends that reality into what comes next.


If this is true, then surely that will follow.


The distinction seems simple. Its significance becomes apparent when what follows is not what we expected.



What We Have Already Admitted as Fact


When I practised law, we would ordinarily prepare an Agreed Statement of Facts before trial.


Where the parties agreed that something was true, it did not need to be proven. It could be placed before the court as an accepted fact, allowing the trial to focus on what actually remained in dispute.


There is something about that process that I appreciate differently now.


Before a fact was permitted to occupy that position, it had been identified, considered, and agreed upon. Only then could everything that followed proceed on the basis that it was true.


Outside a courtroom, we do something remarkably similar with assumptions. Except there is no equivalent process of admission.


Something enters our understanding as a possibility, an inference, perhaps little more than an impression. Over time, its provisional nature can disappear.


They understood.


This is what was intended.


They knew what I expected.


If something had changed, I would have been told.


We stop reasoning about these propositions and begin reasoning from them.


That distinction matters because once the premises are fixed, everything downstream can be perfectly logical.


The reasoning does not have to be poor.


The judgment does not have to be careless.


The entire chain can be impeccable while depending upon a premise that was never established.


Intelligence offers surprisingly little protection from this. The better we are at analyzing information and constructing coherent explanations, the more convincingly we may be able to reason from whatever premises we have already accepted.


In court, an agreed fact acquired its status deliberately.


In life, assumptions can acquire much the same authority almost invisibly. This raises a question further upstream than most of the ones we ordinarily ask:


What have we already admitted as fact before the reasoning even began?



When an Expectation Is Violated


Once something has acquired the status of fact in our minds, an expectation can follow almost effortlessly.


If my business partner understands that decisions of a certain magnitude are ours to make together, then of course they will speak to me before proceeding.


Then they don't.


The decision itself is observable.


Its meaning is not.


If both people understood that decisions of this magnitude would be made jointly, proceeding alone may reveal something important about trust, respect, partnership, or intention.


But if that understanding was never actually shared, the same event occupies a different landscape. There is an enormous difference between:


They knew, and they proceeded anyway.


and:


I believed they knew.


Yet if they knew has already been admitted into our private statement of facts, we are unlikely to return to it when the expectation is violated.


We ask why they proceeded despite knowing. And without realizing it, we have narrowed the inquiry.


The assumption has influenced not only the answer.


It has determined which questions still appear worth asking.



The Standards No One Knows They Are Being Measured Against


An expectation can become a standard against which another person is evaluated without that person ever knowing the standard exists. This is particularly likely when the expectation feels self-evident.


A CEO gives a senior executive responsibility for an important initiative. The CEO expects to be told if anything develops that could materially affect the outcome. It seems inherent in entrusting someone with responsibility at that level: exercise judgment independently, but make sure there are no consequential surprises.


The executive understands the responsibility somewhat differently. They were given ownership of the initiative. Unless a problem exceeds their authority or becomes something they cannot resolve, they believe they are expected to handle it.


A significant problem develops. The executive sees it, works through it, and eventually resolves it.


The CEO learns about it later.


Nothing ultimately failed. But something has changed.


The CEO is troubled that a problem of that magnitude was never disclosed. The executive is surprised by the reaction; from their perspective, handling difficult problems without unnecessarily escalating them was part of the responsibility they had been given.


Neither expectation is inherently unreasonable. The difficulty is that each person believed their understanding of the responsibility was already shared.


Now the CEO may begin wondering whether the executive knows when to escalate. The executive may begin wondering how much authority they actually have.


What appears to be a disagreement about one incident can quietly become a judgment about capability, trust, autonomy, or leadership. Yet those judgments may be developing from an expectation neither person realized the other understood differently.


What did each person believe had already been agreed?


Sometimes what appears to be a problem of behaviour began much earlier, in the assumptions that gave the behaviour its meaning.



Assumptions Can Shape the Evidence


We tend to think of assumptions as affecting the conclusions we reach.


Their influence can begin earlier.


An assumption can affect what attracts our attention, what we regard as significant, what information we seek, which explanations seem plausible, and which questions occur to us.


Suppose we have begun to question someone's judgment. Their next questionable decision attracts attention.


An ambiguous decision may now appear less ambiguous. A choice that might once have prompted curiosity begins to fit an emerging pattern. Over time, we may accumulate substantial evidence for the conclusion.


The evidence may be entirely real. But another question has become relevant:


How much of what we now regard as evidence became significant only after we had already begun to believe the conclusion it appears to support?


This does not tell us that the conclusion is wrong.


It tells us something about the conditions under which the evidence acquired its meaning.



When Interpretation Begins Shaping Reality


The influence can extend further still.


An interpretation rarely remains confined to thought.


A leader who has become concerned about someone's judgment may exercise greater oversight.

The person senses the reduced autonomy and becomes more cautious. Decisions that might once have been made independently are checked first.


The leader observes the increased dependence. It appears to confirm the original concern.


At this point, the evidence is real. But it is being produced inside a system already altered by the conclusion it appears to support. An interpretation of reality has become one of the forces shaping it.


The question is no longer only whether the original judgment was correct. There is now another:


How much of what we are observing did we discover — and how much developed inside the conditions our earlier conclusions helped create?


The distinction may be difficult to recover.


But it can materially change what the evidence is capable of telling us.



The Questions That Disappear


Perhaps the most consequential effect of an assumption is not the conclusion it produces. It is the inquiry it prevents.


If I have accepted that someone knew, I do not ask whether they knew.


If I have accepted that an executive lacks initiative, I may stop wondering what happens when they exercise it.


If I have accepted that a relationship is no longer capable of repair, new information arrives inside a future I have already begun to close.


The missing question leaves no obvious trace.


We notice unanswered questions.


We rarely notice the questions that no longer exist for us.


Yet a question that never occurs to us cannot reveal whatever its answer might have changed.


This is where assumptions begin to shape more than interpretation. They can shape the boundaries of inquiry itself.


A decision made within those boundaries can still be thoughtful, rigorous, and exceptionally well reasoned. We may have considered every possibility we could see.




The Assumptions Least Likely to Be Questioned


It is tempting to think that the assumptions most worth examining are the obviously irrational ones.


Perhaps the opposite is more often true.


An implausible assumption attracts scrutiny because it looks like one. A reasonable assumption can pass unnoticed.


Of course an experienced executive understands this.


Of course my partner knows.


Of course they would tell me.


Each may be correct. But reasonableness is not proof.


Some assumptions may become particularly influential precisely because they fit so comfortably among the surrounding facts.


They do not feel like leaps.


They feel like continuity.


And so they become part of the foundation from which more visible judgments are made.



The Difficulty of Seeing From Inside Our Own Understanding


There is an inherent difficulty in examining assumptions once they have become part of what we know. We use them to evaluate everything else.


They can become embedded in the questions we ask, the evidence we find persuasive, the explanations we consider plausible, and the possibilities we believe remain available.


We are attempting to examine our understanding from inside the understanding we are trying to examine.


This is not a failure of intelligence.


It is a limitation of perspective. And it creates an unusual problem:


The questions most capable of changing our understanding may be precisely the questions we no

longer know to ask.



The Premises We Proceed From


An Agreed Statement of Facts did not exist because everything should be questioned. It existed because some things had already been established.


That distinction mattered.


Once a fact was agreed, we could reason from it. What remained uncertain, disputed, or unproven had to be treated differently.


Outside the courtroom, those distinctions are rarely so explicit.


A fact can sit beside an assumption. An assumption can produce an expectation. An unmet expectation can acquire an interpretation. And by the time a decision needs to be made, the distinctions between them may be difficult to recover.


This does not mean the conclusion is wrong.


Sometimes examination leads directly back to where we began. The other person did know. The expectation was understood. The evidence supports the interpretation. But now we know what the conclusion rests upon.


In other situations, the examination stops much earlier. Something we had been treating as established turns out never to have been established at all.


That matters because consequential decisions are often scrutinized at the end of the reasoning process.


We compare options. We assess risk. We consider consequences. We ask whether the decision can be justified.


But the quality of that analysis still depends upon what entered it as fact.


A decision can be carefully reasoned and still inherit an assumption that was never examined because it no longer looked like one.


That is what I find so useful about the discipline of an Agreed Statement of Facts. Before anything could be built upon a fact, its status was clear.


Agreed.


Not likely.


Not reasonable.


Not what everyone surely understood.


Agreed.


We rarely have that certainty in the situations that matter outside a courtroom.


But there is value in knowing where certainty ends. Because sometimes the question before a consequential decision is not yet:


What should I do?


It is:


What, exactly, am I treating as true?
