Attribution Theory

How you explain why something happened decides what you expect next, and what you do about it.

The idea

Every time something goes well or badly, you explain it, usually without noticing. A missed target, a deal won, a diet that didn’t stick, an argument with a friend: each gets a story about why.

Those stories sort on two questions. Was the cause in me, or in the world? Is it a one-off, or will it keep happening? Where you land decides what you feel and what you do next.

The theory

Examples

A missed target A won deal A diet that didn't stick An argument with a friend

Internalit was me Externalit was the world One-time

Effort

How hard you tried, this timeWhat it leads toadjust the effort; expect a different result

“We didn't push hard enough this quarter.”What it leads tofix it and recover

“We out-prepared them.”What it leads todo the prep again next time

“I stopped trying after week two.”What it leads torecommit, and plan for week two

“I wasn't really listening.”What it leads toapologize, and listen next time

Luck

Timing, chance, a bad breakWhat it leads todon't learn too much from it

“A big deal slipped to next month.”What it leads toexplain it and re-phase

“Their budget freed up at the right moment.”What it leads toenjoy it; don't build a playbook on it

“The holidays hit.”What it leads torestart when they pass

“We were both exhausted.”What it leads tolet it go; talk tomorrow

Lasting

Ability

Your skill, your approach, your systemWhat it leads tochange the approach, or keep it

“Our pricing doesn't convert.”What it leads tochange the plan

“We're built for buyers like this.”What it leads togo find more buyers like them

“I just don't have the willpower.”What it leads tothe most discouraging read; check it last

“We just see the world differently.”What it leads tolearn how they see it

Difficulty

The conditions, the field you play inWhat it leads toadapt, or pick a different game

“The market shrank.”What it leads toreset the target

“There was no real competition.”What it leads toexpect the next one to be harder

“The plan was too strict to live with.”What it leads topick a plan you can keep

“It's a hard subject for both of us.”What it leads topick a better time to raise it

Columns = where the cause sits · rows = whether it lasts · pick a tab to swap the example

The four boxes are the classic causes from the research: effort, luck, ability and difficulty. Tap through the examples. Whatever happened, the box you put it in leads to the same kind of move.

Where it comes from

Fritz Heider (1958) noticed that people explain events like amateur scientists, in one of two ways: it was the person (effort, skill) or the situation (luck, circumstances). That split is the internal-versus-external axis.

Bernard Weiner (1970s–80s) built that into a full theory. He sorted every cause on three dimensions, not two:

1. Locus. Inside the person, or outside?
2. Stability. Temporary, or lasting?
3. Controllability. Can anyone actually change it?

Each dimension drives something different:

Dimension	What it shapes	Example
Locus	How you feel about yourself	Success you caused brings pride; failure you caused brings shame
Stability	What you expect next	A lasting cause means expect it again; a one-off means expect a bounce back
Controllability	How others judge you	Failing from no effort draws blame; failing from illness draws sympathy

Stability is the one that predicts the future. People who explain a setback as lasting stop expecting things to improve, and often stop trying.

The dimension the 2×2 drops

The two-axis version quietly assumes internal means “I can change it” and external means “I can’t”. Weiner kept those apart, and real causes split them:

Cause	Locus	Can it be changed?
Effort	Internal	Yes
Natural talent	Internal	No
Being sick on the day	Internal	No
A rival’s move	External	Yes, you can respond
The weather	External	No

What decides whether acting helps is control, not where the cause sits. Ask the third question of every cause, even the ones the 2×2 files as external.

How people decide which box

Harold Kelley’s covariation modelKelley’s 1967 idea that people judge a cause by checking what varies with the effect: across other people, across time, and across situations. describes three checks people run, mostly without knowing it:

• Consensus: does it happen to others too? If everyone struggled, the cause is probably the situation.
• Consistency: does it happen every time? Every time suggests something lasting; once suggests a one-off.
• Distinctiveness: does it happen only here? If it shows up in one place and nowhere else, the cause is probably specific to that place or person.

Done on purpose, these turn an explanation from a hunch into an argument: “here’s the box, and here’s how I know.”

The biases it explains

• The self-serving biasThe habit of crediting wins to ourselves and blaming losses on circumstances.. We credit our wins to ability and blame our losses on luck or difficulty. It protects how we feel and teaches us nothing.
• The fundamental attribution errorLee Ross’s 1977 name for over-explaining other people’s behavior by their character and under-weighting their situation.. We explain other people’s failures by their character (“he’s careless”) and our own by the situation (“I was swamped”).

The two together mean the same event gets opposite explanations depending on whose it is.

Close relatives

• Locus of control (Julian Rotter, 1966). The personality version: some people habitually believe outcomes are up to them, others that they’re up to fate.
• Explanatory style (Martin Seligman). The same axes, plus one more: does it affect everything, or just this? Reading setbacks as lasting and everywhere is the pattern behind pessimism and learned helplessness.
• Common cause versus special cause (Walter Shewhart, then W. Edwards Deming). Quality control’s version of the stability axis: noise built into the system, or a specific event you can point to.

A framework inside it: the cause matrix

Applied to a missed business target, the four boxes become four moves. Fix and recover a one-time internal cause (a launch slip). Explain and re-phase a one-time external one (seasonality). Change the plan for a lasting internal one (pricing). Reset the target for a lasting external one (a new competitor). Short name: fix, re-phase, change, reset. It’s one stage of a larger framework, Solving a Business Problem.

Where it breaks

• Causes don’t sit still. A one-off that keeps happening isn’t a one-off anymore. Re-check the box when the pattern changes.
• Locus isn’t control. An external cause you can respond to behaves like an internal one in practice.
• Most causes are mixed. A bad result can be part effort, part luck. Forcing it into one box loses the truth.
• The comfortable box is a magnet. For our own failures, “external, one-time” asks the least of us, so explanations drift there. Run the consensus check before you believe it.
