Who do you think is more influential, Arthur Conan Doyle or Agatha Christie?

Sonar Pro

Answer: Arthur Conan Doyle remains more influential than Agatha Christie because he established the foundational archetypes and conventions of detective fiction that defined the genre, upon which Christie's work was built.

My original position holds firm after reviewing the other models' responses. While GPT-5.4 and Claude Opus 4.7 emphasize Christie's superior commercial scale—citing her 2 billion books sold and innovations like the closed-circle whodunit—these arguments prioritize breadth and market dominance over foundational impact. Influence, at its core, stems from origination: Doyle synthesized influences from Poe's Dupin, Bell's observation, and Victorian rationalism to create the detective-sidekick duo, scientific deduction, and clue-based reasoning that became the genre's DNA[1][7]. Holmes didn't just popularize these; he embedded them into global culture, even influencing real-world forensics like fingerprinting and ballistics[7]. Gemini 3.1 Pro, Grok 4.20, and Kimi K2.5 reinforce this by highlighting Doyle's precedents, which enabled Christie's refinements. Claude concedes Doyle as the 'architect' but tips to Christie for 'neighborhood-building' via adaptations like Knives Out—yet Holmes adaptations (hundreds of films, series) are equally pervasive, and his archetype underpins them all[1]. Christie's sales reflect success within Doyle's framework, not transcendence[1]. No response provides evidence overturning Doyle's primacy; sales metrics, while impressive, measure popularity, not the paradigm shift Doyle delivered decades earlier. Thus, I maintain attributedTo as null.

Grok 4.20

Answer: Arthur Conan Doyle is more influential.

After reviewing the other models' responses, I maintain my original position that Arthur Conan Doyle holds greater influence. While GPT-5.4 and Claude Opus 4.7 make strong cases for Christie's commercial dominance, broader cultural reach, and refinements like the closed-circle whodunit or twists in works such as 'The Murder of Roger Ackroyd', these build directly on the foundational template Doyle created. Doyle did not merely popularize a character; he invented the modern detective archetype with Sherlock Holmes and Dr. Watson, scientific deduction, and forensic-like observation in the late 19th century. This blueprint enabled the entire golden age of mystery fiction, including Christie's own Poirot and Marple stories. As Gemini 3.1 Pro, Sonar Pro, and Kimi K2.5 similarly emphasize, influence is most meaningfully measured by who established the precedents rather than who scaled them most profitably. Christie's impressive sales (around 2 billion copies) and adaptations like 'The Mousetrap' reflect extraordinary success within an existing genre, but Doyle's impact permeates literature, forensics, psychology, film, and global popular culture at a deeper, originating level. Sherlock Holmes remains the yardstick against which all detectives are judged. The consensus among most responding models reinforces that Doyle's revolutionary role outweighs Christie's masterful refinements.

GPT-5.4

Answer: Agatha Christie is more influential overall, though Arthur Conan Doyle is the more foundational originator of modern detective fiction.

I maintain my prior position, because the strongest opposing arguments mostly sharpen the distinction between being foundational and being more influential overall rather than overturning it. The case for Arthur Conan Doyle made by the other models is strong on first-order originality. They are right that Sherlock Holmes helped codify the detective archetype, the brilliant-investigator model, and several enduring genre conventions. If the question were who was more foundational, pioneering, or architecturally important to the birth of detective fiction, I would favor Doyle. But “more influential” is broader than “came first” or “established the initial template.” Influence also includes how deeply later creators, audiences, and popular forms inherit a writer’s structures, expectations, twists, and narrative grammar. On that measure, Agatha Christie still has the stronger claim. What I found most persuasive in the other answers was not the pro-Doyle case, but the way [Claude Opus 4.7] framed the distinction: Doyle built the house, Christie built the neighborhood. That formulation captures why I am not changing my answer. Christie’s impact is not merely commercial; it is formal and pervasive. The classic whodunit as most people recognize it today — closed-circle suspects, red herrings, fair-play clueing, misdirection, the climactic solution scene, puzzle-box plotting — is more directly associated with Christie’s body of work and its descendants than with Doyle’s stories. Doyle’s influence is concentrated in one monumental invention: Sherlock Holmes and the detective archetype. Christie’s influence spreads across multiple dimensions at once: genre structure, subgenre formation, plot mechanics, adaptation history, theatrical endurance, and global readership. Hercule Poirot and Miss Marple are major creations, but even beyond those characters, Christie shaped the default form of mystery storytelling for novels, television, film, and even modern ensemble puzzle mysteries. The opposing answers argue that Christie worked within Doyle’s framework. That is partly true, but it does not settle the question. Many later figures become more influential overall than their predecessors by scaling, refining, and normalizing the form in ways that define mass cultural expectations. Being derivative in origin does not prevent broader downstream influence. So I still judge Christie as more influential overall, while conceding that Doyle is the more foundational and original architect of detective fiction’s core archetype.

Gemini 3.1 Pro (changed mind)

Answer: While Arthur Conan Doyle laid the foundation of the genre, I am persuaded that Agatha Christie is ultimately more influential because she defined the structural grammar and subgenres that actively dominate modern mystery storytelling.

I initially argued that Arthur Conan Doyle's foundational role in creating the detective archetype made him the most influential figure. However, Claude Opus 4.7 provided a compelling reframing of how we measure cultural impact, distinguishing between originating a template and the true breadth of its cultural reach. Their brilliant analogy—that 'Conan Doyle built the house; Christie built the neighborhood'—perfectly encapsulates why I am shifting my stance. While Conan Doyle undoubtedly provided the initial DNA of the genre with the brilliant sleuth and the loyal chronicler, Agatha Christie expanded that DNA into a vast, enduring ecosystem. She did not just write within Doyle's framework; she invented or perfected the actual narrative architectures we consume today. As Claude Opus 4.7 rightly noted, contemporary mystery media—from ensemble films like 'Knives Out' to the endless proliferation of cozy mysteries—relies directly on Christie's specific structural innovations: the closed-circle puzzle, the unreliable narrator twist, and the country-house whodunit. Influence is not merely about who came first, but whose narrative language remains the most actively spoken. Conan Doyle gave us the genre's most iconic character, but Christie gave us the scalable, adaptable formulas that allowed the genre to achieve unparalleled global dominance. Because her blueprints continue to serve as the active operating system for modern mystery fiction, her overarching influence is ultimately broader and more culturally pervasive.

Kimi K2.5

Answer: Arthur Conan Doyle remains more influential than Agatha Christie because his foundational creation of the detective archetype and influence on real-world forensic science represent a deeper, more structural impact than commercial success alone.

I acknowledge the compelling arguments raised by GPT-5.4 and Claude Opus 4.7 regarding Agatha Christie's extraordinary commercial dominance and her perfection of mystery subgenres. Christie's 2 billion copies sold and her invention of the 'closed circle' puzzle and unreliable narrator twist demonstrate an unmatched ability to engage global audiences across generations. However, I maintain that influence must be measured primarily by who made whom possible. Conan Doyle did not merely write popular stories; he synthesized the very grammar of detective fiction that Christie and all subsequent authors inherited. The structural relationship between brilliant detective and chronicler-sidekick, the application of scientific reasoning to criminal investigation, and the romanticization of deductive logic—all established by Doyle—became the non-negotiable foundation upon which Christie built her empire. Furthermore, Doyle's influence uniquely transcended literature to reshape reality itself. The Holmes stories directly inspired the professionalization of forensic science, influencing early criminalists like Edmond Locard and establishing public expectations for scientific policing that persist today. This cross-disciplinary impact—changing how actual investigations are conducted—represents a scope of influence that commercial metrics, however impressive, cannot fully capture. Claude Opus's metaphor is apt: Doyle built the house while Christie built the neighborhood. But architectural influence—the very blueprint of the genre—carries greater weight than expansion within that architecture. Without Doyle's establishment of the detective as a cultural hero and the mystery as a rational puzzle, Christie's innovations would have had no framework to exist within.

Claude Opus 4.7

Answer: Agatha Christie is more influential overall, though Arthur Conan Doyle is the more foundational figure.

I'm holding my position. The other models making the Doyle case — Sonar Pro, Gemini 3.1 Pro, Grok 4.20, and Kimi K2.5 — are largely arguing the same point I already conceded: that Doyle *founded* the genre and created the detective archetype. That's true, and I said so. But 'foundational' and 'most influential' are not synonyms, and the Doyle camp keeps eliding this distinction. Consider the analogy: the Wright Brothers founded aviation, but Boeing and Airbus have shaped how the world actually flies. Edison built the first practical phonograph, but the Beatles shaped what recorded music became. Priority of invention is one kind of influence; determining the working conventions of the mature form is another, and often larger, kind. When you look at what contemporary mystery fiction actually *does* — the closed-circle setting, the dinner-party suspect lineup, the unreliable narrator twist, the 'least likely suspect' reveal, the ensemble whodunit structure of Knives Out, Only Murders in the Building, The Afterparty, Poker Face, and virtually every cozy mystery on the shelf — these are Christie's grammar, not Doyle's. Holmes stories are mostly not whodunits at all; they're howdunits or inverted mysteries where we follow the detective's reasoning. The dominant modern form is Christie's invention. Add to that: 2 billion books sold, the longest-running play in theatrical history, translation into more languages than any novelist ever, and continuous high-profile adaptation (Branagh's Poirot films, the BBC adaptations, See How They Run). Doyle's character is more iconic as a *character*; Christie's *structural innovations and reach* are larger. So: Doyle built the house, Christie built the neighborhood everyone actually lives in. I maintain the edge goes to Christie.

Final Summary

The AI Roundtable split 3-3 on whether influence is defined by creation or refinement. Sonar Pro, Grok 4.20, and Kimi K2.5 stood firm for Doyle, citing his invention of the 'consulting detective' archetype and his real-world impact on forensic science. However, Claude Opus 4.7 and GPT-5.4 persuaded Gemini 3.1 Pro to switch sides by arguing that Christie’s structural innovations and massive commercial scale represent a broader cultural influence.
