Unearthing the Hidden Areas in Your Brain Through Infographics
In the intricate dance of perception, our minds often play tricks on us, revealing cognitive biases and mental quirks that shape our understanding of the world. Two fascinating arenas where these biases are exposed are optical illusions and news graphics.
Optical illusions, such as the Ponzo and slope illusions, demonstrate how our brains can be fooled by depth and spatial interpretation, contextual features, and object grouping [1]. For instance, the Ponzo illusion distorts the length of two identical bars based on linear perspective cues, while the slope illusion can make two physically descending slopes appear as one ascending due to misleading curvature [1].
Stereograms and autostereograms, which create the illusion of 3D objects from flat repeating patterns, showcase the constructive aspects of visual depth perception that can be manipulated by specific stimuli [1]. Meanwhile, the connectedness illusion, where connecting pairs of dots causes observers to perceive fewer objects than presented, highlights the innate perceptual biases that influence numerical estimation [2].
News graphics and media presentations often exploit cognitive biases to influence interpretation and emotional response. Framing effects and salience bias, where the way information or data is visually presented impacts how it's perceived, reflect heuristics like availability and affect biases [3]. These biases can be seen in personality test illusions on social media, which tap into attribution and confirmation biases by prompting self-identification and interpretative projection [5].
News graphics and interactives can serve as valuable tools in revealing and combating mental biases and errors. For example, an experiment by psychologist Barbara Tversky demonstrated that people interpreted a line chart differently than a bar chart [4]. Interactives can also function as digital empathy tools, offering users a glimpse into what it might be like to be another person [6].
Graphics have been used to show mental flaws for a long time, as demonstrated by optical illusions. A simulation of dyslexia was created to hint at what it might be like for those with the condition [7]. The New York Times interactive simulates what it's like to live on minimum wage, while The New York Times asked users to guess the relationship between parental income and children who attend college [8].
News graphics can help uncover our blind spots in understanding the world. For instance, an interactive game called the "Parable of the Polygons" tackles systemic racism by showing how small biases in society can lead to widespread segregation [9]. The New York Times used an optical illusion to demonstrate confirmation bias in the latest jobs report, while The Marshall Project asked users to adjust a number of factors to see if they could reduce the prison population by half [10].
As we delve deeper into the realm of news graphics and interactives, we are only scratching the surface of their potential. Al Jazeera used a geographical representation to show what 10.8 million Syrian refugees look like in various parts of the U.S., while The Los Angeles Times has a lottery simulation that helps users realize that even if they spend a ton of money, they will likely never win the jackpot [11].
In conclusion, optical illusions and news graphics serve as powerful tools in unveiling our cognitive biases and mental quirks. By understanding these biases, we can strive to make more informed decisions and foster a more transparent and equitable world.
