The complex, intellectually demanding nature of certain modern video games, particularly those in the Multiplayer Online Battle Arena (MOBA) genre, is leading researchers to re-evaluate their potential as sophisticated measures of cognitive ability, akin to traditional IQ tests. A significant study has highlighted that proficiency in games like "League of Legends" and "Defense of the Ancients 2" (DOTA 2) correlates strongly with higher scores on established intelligence assessments. This finding extends previous research that identified a link between expertise in strategic board games, such as chess, and superior performance on IQ tests, applying it to digital entertainment consumed by millions globally.
The Cognitive Demands of Modern Gaming
The assertion that video games can serve as proxies for intelligence is rooted in the intricate cognitive processes they demand. Unlike simpler forms of entertainment, games like "League of Legends" and DOTA 2 are not merely about reflexes or rote memorization. They require players to engage in continuous strategic planning, adapt to rapidly evolving in-game scenarios, manage multiple resources simultaneously, and collaborate effectively with a team of individuals, often strangers. This multifaceted cognitive load mirrors the challenges presented in high-level problem-solving and strategic thinking, which are central to intelligence assessments.
Professor Alex Wade, who spearheaded the research, emphasized the intellectually taxing nature of these games. "Games such as League of Legends and DOTA 2 are complex, socially-interactive and intellectually demanding," Professor Wade stated. "Our research would suggest that your performance in these games can be a measure of intelligence. Research in the past has pointed to the fact that people who are good at strategy games such as chess tend to score highly at IQ tests. Our research has extended this to games that millions of people across the planet play every day."
A Shift from Reaction to Strategy
The study’s findings also revealed a fascinating dichotomy in how different game genres relate to cognitive development and aging. While first-person shooter (FPS) games, which primarily rely on rapid reaction times and precise aiming, showed a decline in player ability after adolescence, strategic games demonstrated a different trend. Participants generally improved their performance in MOBA titles like "League of Legends" and DOTA 2 as they aged.
This observation is particularly noteworthy. It suggests that the cognitive skills most crucial for success in MOBAs—memory, strategic foresight, and complex decision-making—are not only preserved but can be honed and refined over time. This contrasts with the more physically demanding or reflex-based skills that might naturally diminish with age.
Mr. Athanasios Kokkinakis, the study’s lead author, elaborated on this distinction: "Unlike First Person Shooter (FPS) games where speed and target accuracy are a priority, Multiplayer Online Battle Arenas [such as League of Legends] rely more on memory and the ability to make strategic decisions taking into account multiple factors. It is perhaps for these reasons that we found a strong correlation between skill and intelligence in MOBAs."
The Scientific Basis: Correlation and Cognitive Function
The research, published in the peer-reviewed journal PLOS ONE (Kokkinakis et al., 2017), investigated the cognitive profiles of players across different game genres. The study aimed to understand which specific cognitive abilities were being exercised and how these related to general intelligence. Traditional intelligence tests, such as those administered on paper, typically measure a range of cognitive functions including logical reasoning, spatial visualization, verbal ability, and working memory.
The correlation found between MOBA proficiency and IQ scores suggests that the cognitive functions central to excelling in these games overlap significantly with those measured by IQ tests. These functions likely include:
- Executive Functions: This broad category encompasses planning, working memory, cognitive flexibility, and inhibitory control – all critical for managing multiple objectives, adapting to enemy strategies, and making real-time decisions in MOBAs.
- Fluid Intelligence: The ability to reason and solve novel problems, independent of acquired knowledge. MOBAs constantly present new challenges and require players to think on their feet.
- Working Memory: The capacity to hold and manipulate information in the mind. Players need to remember enemy positions, cooldowns of abilities, and strategic objectives.
- Spatial Reasoning: While not as dominant as in some other genres, understanding the game map, predicting enemy movements, and positioning characters effectively involves spatial awareness.
- Strategic Thinking: The overarching ability to formulate plans, anticipate consequences, and adapt tactics based on changing circumstances.
The study’s methodology likely involved recruiting a diverse group of gamers and non-gamers, administering a battery of cognitive tests, and then correlating performance on these tests with their in-game skill levels in various video game genres. The statistical analysis would then identify significant relationships, controlling for potential confounding factors.
Background and Context of the Study
The research emerged from a growing interest in understanding the cognitive impacts of digital engagement. For years, video games have been subjects of both praise for their potential developmental benefits and criticism for their perceived negative effects. This study aimed to provide a more nuanced, evidence-based perspective by examining the specific cognitive demands of popular, complex video games.
The rise of MOBAs like "League of Legends" (released in 2009) and DOTA 2 (released in 2013) marked a significant evolution in the gaming landscape. These games are free-to-play but boast massive player bases and sophisticated competitive scenes, often involving millions of dollars in prize money for professional tournaments. Their complexity stems from their real-time, team-based nature, requiring deep understanding of numerous characters, items, and strategic interactions. Unlike earlier strategy games that might have been played against AI or a single opponent, MOBAs present dynamic, unpredictable environments shaped by the actions of ten individual players.
The academic pursuit of understanding intelligence itself is also a long-standing field. The concept of IQ, or intelligence quotient, was developed in the early 20th century to measure an individual’s cognitive abilities relative to their age group. While IQ tests have been subject to debate regarding their cultural bias and what precisely they measure, they remain a widely accepted tool in psychology for assessing general cognitive capacity. Linking video game performance to these established measures provides a novel avenue for exploring cognitive strengths and potential.
Chronology of Research and Findings
- Early 2000s onwards: Research begins to explore the cognitive benefits of video games, particularly strategy games like chess, linking them to enhanced problem-solving skills and higher IQ scores.
- 2009: "League of Legends" is released, quickly gaining a massive global following and establishing the MOBA genre as a dominant force in online gaming.
- 2013: DOTA 2, a direct successor to the popular "Defense of the Ancients" Warcraft III mod, is released, further solidifying the MOBA genre’s popularity and complexity.
- Circa 2017: Professor Alex Wade and his team at an unnamed institution (likely a university with a psychology or cognitive science department) conduct their study investigating the correlation between MOBA performance and cognitive abilities. The study focuses on "League of Legends" and DOTA 2.
- Publication in PLOS ONE (2017): The research findings are formally published in the journal PLOS ONE, detailing the strong correlation between skill in MOBAs and performance on standard intelligence tests. The study also contrasts this with findings for first-person shooter games.
- Post-Publication Analysis: The study’s implications begin to be discussed within academic circles and popular science media, highlighting the potential of video games as informal cognitive assessment tools and indicators of strategic thinking prowess.
Broader Implications and Future Directions
The implications of this research are far-reaching. Firstly, it offers a compelling argument for the cognitive benefits of engaging with complex video games. For individuals who excel in MOBAs, their gaming prowess may be a testament to their strong analytical and strategic minds. This could potentially shift perceptions of gaming from a mere pastime to an activity that cultivates valuable cognitive skills.
Secondly, the findings could inform educational and developmental strategies. If certain games are indeed reflective of intelligence, they could be explored as supplementary tools for cognitive assessment or even as engaging platforms for cognitive training, particularly for developing executive functions. The fact that performance in these games can improve with age, unlike skills relying purely on reaction time, suggests their suitability for a wider age range and for fostering lifelong cognitive engagement.
From a recruitment perspective, particularly in fields that demand high levels of strategic thinking, problem-solving, and teamwork, a candidate’s demonstrated skill in complex strategy games might offer valuable insights into their potential. While not a replacement for traditional qualifications, it could serve as an additional, albeit unconventional, indicator of cognitive aptitude.
However, it is crucial to maintain a balanced perspective. Correlation does not equal causation. While the study found a strong link, it doesn’t definitively prove that playing MOBAs causes higher intelligence. It is equally plausible that individuals with a higher innate intelligence are naturally drawn to and excel at these demanding games. Further longitudinal studies would be beneficial to explore the causal relationship and the potential for cognitive enhancement through targeted gaming interventions.
The research also opens doors for further investigation into other game genres and their respective cognitive correlates. Understanding the specific cognitive demands of diverse gaming experiences can lead to a more comprehensive understanding of how digital interactions shape and reflect human cognition. As video games continue to evolve in complexity and popularity, their role as mirrors of our cognitive capabilities is likely to become an increasingly significant area of study.
