One-sided stories present a single perspective as if it were the complete, balanced account. Where cherry-picking (T13.1) selects among individual facts, this technique selects among whole viewpoints: one party’s version of events is told in full and persuasive detail while the opposing side is omitted rather than answered. The result feels authoritative precisely because nothing in it pulls the other way — but that seamlessness is manufactured by absence, not earned by argument.
The mechanism is the availability heuristic and confirmation bias working together. The audience judges from the account in front of them, and a version with no visible counterweight reads as obviously correct; the human tendency to accept the first coherent story compounds the effect. It is the workhorse of propaganda, partisan reporting, public relations, and everyday interpersonal disputes, where a single sympathetic telling can settle opinion before the other party is ever heard. Because it typically serves a chosen storyline, it pairs closely with narrative framing (T13.6); its mirror image is uncertainty flooding (T13.18), which inflates a fringe side to unsettle a well-established account.
The counter is a deliberate habit rather than a one-time check: assume any single-perspective account is incomplete until you have actively sought the other side. Ask which voices are described but never quoted, go find their actual words, and build the strongest honest version of the opposing case. Above all, treat the feeling of clean completeness with suspicion — genuine situations rarely resolve without credible tension, so an account that leaves nothing to weigh has usually had the weighing removed for you.
