The Decision Premise: How Upstream Assumptions Shape the Choice
A decision premise is an assumption a choice treats as settled. In the reverse-centaur risk, automated output supplies those assumptions while a person signs.
A CONCLUSION FROM PREMISES
A claim about the world meets a choice about what matters.
A factual premise is an empirical claim, which may be mistaken. A value premise specifies an objective or preference. In the campaign memo, reported performance and the chosen target supply different reasons for acting. Neither removes the need for judgment. The reverse-centaur risk grows when these premises arrive as instructions. Separating them helps locate prediction and decision: evidence can inform a choice, while its purpose remains open to examination.
SIMON’S DECISION PREMISES
Simon put the decision inside the organization.
Herbert Simon's Administrative Behavior first appeared in 1947. Its distinction between facts and values helps explain how a recommendation acquires authority. The edition cited here is the fourth, published in 1997; its first chapter connects decision making, organizational influence and accepted authority.
ACCEPTED PREMISES
A target can govern without being argued again.
Simon distinguishes accepting authority from being persuaded: a person follows another's decision without independently examining its merits. Authority in this sense can also operate upward or sideways. In the campaign example, treating the target as given lets an earlier choice govern the review. The person signing needs a route to question it, including escalation to whoever can change it.
The pen is only one place to look for influence.
A reviewer can retain discretion while reasoning inside a frame supplied by someone else. The person who fixes the option set has already shaped what reaches the desk.
UNCERTAINTY ABSORPTION
The summary travels farther than its evidence.
March and Simon call this uncertainty absorption: an inference is communicated in place of the evidence from which it was drawn. In the campaign example, “under target” can travel while the attribution choices, reporting window and caveats remain with the analyst. A summary can be useful. Compression also changes what the receiver can inspect. Retaining access to the evidence gives a challenge somewhere to go.
WHAT TRAVELS, WHAT STAYS
Uncertainty absorption takes place when inferences are drawn from a body of evidence and the inferences, instead of the evidence itself, are then communicated.

Andrew Pettigrew's 1972 study examines a gatekeeper filtering information during an innovative decision process, within an organization and across its boundaries. It treats information control as a power resource. This supports asking what the gatekeeper made available; it does not establish that the gatekeeper alone determined the outcome. A curated menu poses a related question about what the recipient gets to consider. Source: Pettigrew, “Information Control as a Power Resource,” Sociology 6(2), 187–204; abstract.
THE WELD
A measured return and a chosen target answer different questions.
Return on ad spend, or ROAS, can report attributed revenue divided by advertising spend. Its meaning depends on measurement choices, including attribution and the reporting window. Choosing a minimum acceptable ROAS adds a decision criterion; the measurement does not select that target. A model can help estimate performance or compare proposed objectives under stated assumptions. Accountable people still need to examine both. Even a sound “below target” result leaves choices about testing, waiting or stopping. This is where prediction meets decision.
IN THIS FRAMEWORK
The recommendation and the menu both carry premises.
In a recommendation treated as an instruction, a performance claim can arrive attached to an objective. In the construction of a menu, expectations about the options can arrive attached to a preference for one kind of outcome. Each contains empirical and evaluative choices. A curated set may restrict what is considered without removing all discretion. Useful review can question the evidence, the objective and the exclusions.
WHO SUPPLIED THE PREMISE
Trace the claim. Find the target's owner.
Before accepting a finding as a reason to act, identify its empirical claim, the objective it serves and who supplied each. A descriptive sentence need not contain a hidden value judgment; its use in a decision may still depend on one. Keep a route to the evidence and to whoever can revise the objective. Then inspect which options made the menu.
