Unveiling the Hidden Blind Spots in Your Brain through Data Visualization
=====================================================================
In the modern world, graphics and visual tools have become more than just a means to present data; they play a critical role in influencing perceptions, shaping decisions, and engaging decision-makers. This article explores various studies and examples that demonstrate the impact of external factors on decision-making and judgment, and how visual tools help illustrate these effects.
A 2025 study on career or study choices highlights how external factors such as peer groups, family, teachers, university admission requirements, and time pressure impact decision-making. This study discusses the complexity due to multiple external influences and how these shape decisions in a nonlinear process. Another recent study on emergency department admissions shows how non-clinical external factors like patient anxiety, family insistence, and systemic issues drive hospital admission decisions.
Visualization research indicates that graphics not only present data but also influence how information is received and interpreted. One paper shows that visual design choices in graphics can affect viewers’ social and political impressions of the information source, which may impact how users engage with and trust data. For example, aesthetic design of graphs can induce strong, consistent inferences about the creator’s identity or intent beyond the raw data itself.
Reviews of AI-assisted decision-making also underline the importance of usability, interactivity, and accessibility of visualization tools to support clearer and more informed decisions.
Examples of graphics that put the user in the driver's seat include The New York Times' interactive illustrating the relationship between parental income and children who attend college, requiring users to make decisions or do something to understand the story or point. The South China Morning Post uses a similar strategy to imagine what would happen if an atomic bomb hit various cities. Josh Worth uses side-scrolling to show the distance between planets in our solar system.
Small words can change our memories, an effect called priming, while the framing of information can drastically alter people's choices. The New York Times used a scrolling technique to show how many homes were on the brink of foreclosure in 2014, while Al Jazeera uses an unexpected geography to show what 10.8 million Syrian refugees look like in various parts of the U.S.
Optical illusions are a type of graphic that can show the power of graphics to challenge our perceptions. Mental tendencies like loss aversion lead to poor investment decisions, as seen in the average investor's tendency to underperform and make decisions that go against their initial intentions. According to linguist George Lakoff, conceptual metaphors are deeply internalized and can drive judgments and decisions based on irrelevant factors.
Some graphics and interactives, like The New York Times interactive simulating what it's like to live on minimum wage, help users understand complex issues by placing them in simulated scenarios. The Los Angeles Times has a lottery simulation that helps users realize that even if they spend a lot of money, they will likely never win the jackpot. The "Parable of the Polygons" is a game that tackles systemic racism and shows how small biases can lead to widespread segregation. The Marshall Project asks users to adjust factors to see if they can reduce the prison population by half.
In summary, external factors such as social environment, systemic pressures, and even presentation style clearly influence decision-making and judgment. Visual tools help illustrate these effects by making abstract influences concrete, guiding interpretation, and facilitating understanding of complex data and scenarios.

Science plays a significant role in understanding the impact of external factors on decision-making, as demonstrated by studies concerning career or study choices and emergency department admissions. These studies reveal how visual tools, a part of the broader field of technology, can help illustrate these effects, shaping the way data is received and interpreted, thereby influencing lifestyle choices and judgments.
Moreover, advancements in AI and technology are enhancing the usability, interactivity, and accessibility of visualization tools to further support clearer and more informed decisions in various aspects of life.
