Being in the Same Situation Does Not Mean Having the Same Responsibility

A shared situation does not make all actions shared

Two people maintain an everyday agreement. One of them needs to change it and raises the issue. The other listens and responds.

The first action belongs to the person who made the request. The response belongs to the person who responded.

That seems obvious until the situation becomes more complicated.

If the agreement ends badly, if an argument appears, or if one person makes a decision that affects the other, it is easy to start talking about “what both of them did” as though being in the same relationship automatically distributed the actions and their consequences.

It does not.

Two people can be part of the same situation and still have done different things, under different conditions, with different effects.

Before asking who is responsible for what, a more concrete question is needed: what did each person actually do?

Being affected by an action does not mean you caused it

Other people’s decisions can profoundly change a person’s life.

Someone may end a relationship, break an agreement, hide information, change their mind, or make a decision that produces consequences for another person. Receiving those consequences does not mean that person made the decision.

That does not mean there is never an action of one’s own that can be examined. A person may have accepted an agreement, hidden information, postponed a conversation, or made decisions that also had consequences.

But those actions need to be analyzed separately.

The fact that a person did something within the situation does not allow it to be used to automatically explain everything the other person did.

This difference matters because some formulas easily mix experience and causality. “If it happened to you, some part of you created it” or “if you stayed, then you allowed it” turn a complex situation into a conclusion that may not be supported by the facts.

Staying, remaining silent, or accepting something at a given moment does not by itself allow us to reconstruct how much a person knew, what alternatives they had, what consequences they anticipated, or what conditions constrained their decision.

The final behavior provides information. It does not by itself distribute responsibility.

A shared relationship does not imply symmetrical responsibility

Imagine an argument.

One person makes a hostile criticism. The other withdraws from the conversation.

We can describe both actions.

We can also investigate whether the withdrawal increased the distance, whether the criticism appeared after other tensions, or whether there were relevant antecedents.

What we cannot do is turn the existence of two actions into equivalent responsibility for everything that happened.

Saying “both contributed” is still too imprecise if we do not know what each person contributed to and through which action.

A relationship does not make power, information, resources, the ability to leave, or the consequences each person faces equal.

That is why being in the same situation does not mean having had the same influence over it.

Nor does it mean that all responsibility has to be distributed.

Sometimes there will be actions clearly attributable to each person. In other cases, some causal relations will remain insufficiently established.

Recognizing your own action does not explain the other person’s action

Suppose a person recognizes that they avoided talking about a problem for months.

They can describe that omission as their own and examine what consequences it had. Perhaps the conversation happened later, perhaps tension accumulated, or perhaps information that would have been useful earlier was lost.

That recognition does not automatically explain what the other person did afterward.

If the other person lied, broke an agreement, responded with hostility, or made another decision, that action needs its own attribution.

An earlier action can be part of the context without thereby becoming a sufficient cause of the later action.

This distinction also makes it possible to separate responsibility from moral condemnation.

In this article, talking about responsibility does not mean deciding whether someone is a good or bad person. It means being able to identify which action belongs to whom and what relation to what happened can be supported.

A person can recognize an action of their own without concluding that everything else happened “because of them” or was “their fault.”

They may also find no relevant action of their own for a particular event without that meaning they refuse to look at the situation.

Conditions change what can be attributed

It is not enough to observe what a person ultimately did. The conditions under which they acted also matter.

Remaining silent with someone who can be contradicted without relevant consequences is not the same as remaining silent when there is a concrete threat. Accepting an agreement with sufficient information is not equivalent to doing so under pressure or dependence. Staying in a situation with accessible alternatives is not the same as staying when leaving involves risks or costs that are difficult to sustain.

These differences do not automatically determine who is responsible for what.

They do prevent a simpler conclusion: using the final behavior as sufficient evidence of consent, freedom, or responsibility.

There can be actions of one’s own carried out under significant constraints. There can be decisions made with broad room to act. There can also be situations in which the available information does not allow those two cases to be distinguished with enough precision.

Attribution needs to preserve those differences rather than erase them.

Asking is not deciding for the other person

Let us return to the initial agreement.

One person can ask for something to change. That request is an action of their own.

The other person can accept, refuse, propose something else, or decline to have the conversation. That response is a different action.

The way the request was made may be relevant to understanding the interaction. But it does not automatically turn the other person’s response into a consequence attributable to the person who asked.

A request does not control the response.

A boundary does not control what another person will do in response to that boundary either.

This difference allows a relationship to be examined more precisely: an action of one’s own can be recognized without absorbing the agency of the person on the other side.

It also avoids a common retrospective conclusion: thinking that if something could have been said differently, then any later response is explained by how it was said.

Sometimes we cannot attribute everything

There are situations in which some facts are clear and other relations are not.

It may be known who said something, who made a decision, or who broke an agreement. At the same time, it may not be known with enough certainty how much an earlier omission influenced what happened, what would have happened under other conditions, or how much weight each element had within a long sequence.

There is no need to turn that uncertainty into symmetry.

Saying “surely both were responsible” is no more precise than attributing everything to one person when the data do not support doing so.

It may be possible to identify an action of one’s own clearly and leave another causal relation open. It may also be the case that a third party’s action is sufficiently established while another person’s participation in that event cannot be supported.

In MAT, talking about responsibility requires being able to identify which action belongs to whom and what relation to what happened can be supported. Responsibility is not distributed simply because several people are present in the same situation.

That criterion leaves room to recognize one’s own actions when they can actually be attributed and also not to take ownership of someone else’s actions.

What happens afterward is another question

Once something has happened, new decisions can appear.

That question matters, but it is a different one.

What a person may be able to do afterward does not retrospectively change who made a decision, who broke an agreement, or who carried out an earlier action.

And not having caused something does not, by itself, answer what possibilities exist now.

That problem will be the next step in the series.

Distinguishing what each person did does not resolve everything. But it avoids an important confusion: turning a shared situation into shared responsibility by default.

Recognizing an action of one’s own does not make another person’s action one’s own.
