Brownian Motion of Organizational Decisions
Major organizational decisions can emerge from accumulated bargains among middle-ranking actors, with leaders later translating the result into a coherent top-down rationale. The official explanation may be the decision’s public face rather than its causal history.
The general may appear to have made the decision, yet C. P. Snow described decisions as arising from the Brownian motion of colonels, majors, and captains—leaving the general chiefly to rationalize the outcome afterward.
E1Many small bargains become one official decision
An organization is not a single mind. People below the top negotiate constraints, protect interests, trade support, and narrow the available options. Their local moves accumulate until one outcome becomes easiest—or unavoidable—for leadership to endorse. The leader then supplies a unified explanation because institutions need decisions to look intentional and accountable, not accidental and negotiated. This is the political mechanism in Allison's Three Models of Decision-Making: the final choice may be less a clean act of optimization than the residue of bargaining among insiders.
E1Where it shows up
The general’s retrospective strategy
Snow’s military hierarchy separates authorship from authorization. Officers throughout the organization generate the path through their interactions; the general gives that path a legible strategic story. Authority over the announcement is not necessarily authorship of the outcome.
E1A rationale is not automatically a cover story
Snow’s claim is that stated reasons were not always close to the true reasons—not that they were never close. Some decisions may genuinely follow a leader’s intent, and a retrospective explanation can accurately describe an outcome even when it omits the bargaining that produced it. The model is a warning against assuming top-down causation, not proof that every official account is false.
E1Reconstruct the path before judging the rationale
For the next consequential decision you encounter, write down who narrowed the options, which intermediate approvals or bargains changed the proposal, and when the announced rationale first appeared. Compare that sequence with the official explanation; treat any gap as a question about causation, not immediate evidence of deception.

CP Snow: decisions "arise from a sort of Brownian motion of colonels and majors and captains and the most the general can do is rationalize it afterwards... the reasons given were not always close to the true reasons."
