Introduction

The X-Files changed UFO investigation storytelling by making the search for extraterrestrial evidence a character-driven investigation rather than a simple question of whether aliens existed. Debuting in 1993, the series transformed UFO narratives into long-running dramas about evidence, belief, institutional secrecy and the difficulty of proving extraordinary claims. Through FBI agents Fox Mulder and Dana Scully, it created a television model where UFO mysteries were explored through competing interpretations rather than a single answer.[Smithsonian Institution]si.eduSmithsonian InstitutionSmithsonian Wants to Believe!

The show’s lasting influence came from this shift in perspective. Earlier UFO fiction often focused on encounters, invasions or the spectacle of alien technology. The X-Files instead asked how investigators decide what counts as proof, how governments control information and how personal experiences challenge scientific assumptions. Its approach helped make UFO investigation a mainstream television storytelling format built around uncertainty.[SHURA]shura.shu.ac.ukSHURAThe Legacy of The X-FilesSheffield Hallam University Research ArchiveApril 19, 2023…Published: April 19, 2023

Mulder and Scully’s opposing approaches

At the centre of The X-Files was a partnership designed around disagreement. FBI Special Agent Fox Mulder investigated the bureau’s neglected “X-Files” — cases involving unexplained phenomena — because he believed evidence of extraterrestrial life and paranormal events had been ignored or suppressed. Dana Scully, a medical doctor and FBI agent, was assigned as his partner to apply scientific methods and challenge conclusions that lacked proof.[Smithsonian Institution]si.eduSmithsonian InstitutionSmithsonian Wants to Believe! National Museum of American History Acquires X-Files Collection | Smithsonian Instit…

This contrast changed how UFO stories worked on television. Instead of presenting belief and scepticism as background attitudes, the series turned them into an ongoing investigative method. Each case became a conversation between two ways of understanding the unknown: Mulder represented openness to possibilities beyond accepted knowledge, while Scully represented the demand for evidence, testing and rational explanation.[Smithsonian Institution]si.eduSmithsonian InstitutionSmithsonian Wants to Believe! National Museum of American History Acquires X-Files Collection | Smithsonian Instit…

The importance of the pairing was that neither perspective completely replaced the other. The show rarely treated scepticism as simple denial or belief as automatic truth. Many episodes created tension by allowing unexplained events to remain unresolved, forcing both characters — and the audience — to live with uncertainty. This structure made UFO investigation feel closer to detective work, where clues accumulate but final conclusions remain difficult to reach.

The relationship also gave UFO storytelling an emotional centre. Mulder’s search was connected to personal loss, especially his childhood memory of his sister Samantha’s disappearance, while Scully’s scientific approach was connected to professional discipline and a desire to understand events through evidence. The mystery mattered because it affected people, not simply because it involved strange objects in the sky.[Smithsonian Institution]si.eduSmithsonian InstitutionSmithsonian Wants to Believe!

Conspiracy and evidence themes

Turning UFOs into investigations of knowledge

A major innovation of The X-Files was moving UFO stories away from the question “what are aliens like?” and towards “how would anyone prove aliens exist?” The series treated evidence as something contested: photographs could be manipulated, witnesses could be unreliable, officials could hide information and scientific explanations could remain incomplete.

This approach reflected a broader television interest in mistrust of institutions during the 1990s. The series connected UFO mysteries with government secrecy, military power and hidden agendas, making alien investigation part of a wider discussion about who controls information. The Smithsonian’s National Museum of American History described the series as using science fiction to address issues including governmental control, conspiracy theories and the possibility of extraterrestrial life.[Smithsonian Institution]si.eduSmithsonian InstitutionSmithsonian Wants to Believe! National Museum of American History Acquires X-Files Collection | Smithsonian Instit…

The show’s long-running “mythology” storyline expanded this idea through a continuing narrative about government efforts to conceal information about alien activity. Unlike traditional episodic UFO stories, where each encounter ended with a clear resolution, The X-Files built a world where answers produced further questions. The investigation itself became the story.[Wikipedia]WikipediaMythology of The X-FilesMythology of The X-Files

The “monster-of-the-week” model and uncertainty

Alongside its larger alien conspiracy storyline, The X-Files used standalone investigations often described by fans and critics as “monster-of-the-week” episodes. These stories allowed the series to explore different explanations for strange events, from possible paranormal activity to human deception or scientific anomalies.[EW.com]ew.comThe piece also notes the enduring appeal and creative reinventions across the series' lifespan, culminating in fan-favorite entries from…

This format strengthened the show’s influence on UFO storytelling because it made investigation repeatable. A television series no longer needed to build towards one final revelation. Instead, mystery could continue through new witnesses, new evidence and new interpretations.

The result was a different kind of science-fiction drama: one where uncertainty was not a failure to solve the story but the central attraction. Viewers were encouraged to examine clues alongside the characters rather than simply wait for an alien reveal.

The show’s cultural legacy

By the end of its original run, The X-Files had become one of television’s most recognisable science-fiction series. It ran on Fox from 1993 to 2002, produced 202 episodes, and later returned for revival seasons. The series became a cultural reference point through phrases such as “The Truth Is Out There”, “Trust No One” and “I Want to Believe”.[Smithsonian Institution]si.eduSmithsonian InstitutionSmithsonian Wants to Believe! National Museum of American History Acquires X-Files Collection | Smithsonian Instit…

Its influence can be seen in later television dramas that combined investigations with larger mysteries, including shows built around hidden organisations, unexplained events and unreliable information. Academic discussions of the series have highlighted how its combination of UFO mythology, conspiracy narratives and complex character relationships helped shape later genre television.[SHURA]shura.shu.ac.ukSHURAThe Legacy of The X-FilesSheffield Hallam University Research ArchiveApril 19, 2023…Published: April 19, 2023

The show also changed the public image of UFO investigation. Investigators in fiction were no longer only scientists, military officials or isolated enthusiasts. They could be ordinary professionals navigating conflicting evidence and institutional barriers. This made UFO stories more personal and more adaptable to television’s long-form storytelling style.

The legacy of The X-Files is therefore not that it settled questions about extraterrestrial life. Its significance lies in changing the way those questions were dramatized. UFO stories became investigations into evidence, trust and the limits of human understanding — a storytelling approach that continues to influence science fiction television.[research.manchester.ac.uk]research.manchester.ac.ukThe legacy of the X-filesResearch Explorer The University of Manchester…
