In a Grove

Akutagawa's 1922 short story presents a single violent event through seven contradictory testimonies, none of which can be reconciled into a master account — a formal argument that objective truth in human affairs may be structurally unavailable, not merely obscured.

For product directors, this is a foundational text on the epistemology of user research: every stakeholder, user interview, and analytics report is a testimony with its own motivated distortions, and synthesising them into a confident 'insight' risks false certainty.

The story predates post-structuralism by decades yet performs its core insight with more economy than most theory.

Kurosawa's adaptation, Rashomon, made the structure famous, but reading the source material reveals how Akutagawa locates unreliability not in villainy but in the ordinary psychology of self-preservation and narrative.

Directors who internalise this are better equipped to hold multiple conflicting signals simultaneously rather than collapsing them prematurely into a roadmap.

The work also disciplines the instinct to build consensus through storytelling — a reminder that a compelling narrative is not the same as a true one.
