Visualizing Cumulative Consequences: Addressing Distance from Effect and Lack of Awareness in Online Commenting
This paper presents a seven-week field study of a browser-based system that visualizes comments on a persistent virtual tree to reduce psychological distance and increase awareness of cumulative consequences, finding that it significantly increased positive and decreased neutral commenting while highlighting the need for randomized controlled trials to confirm causal efficacy.

Every day, millions of people type words into the glowing rectangles of their phones and computers, leaving behind a trail of comments that shape the mood of online communities. While we often think of the worst online interactions as loud, aggressive outbursts, a quieter form of harm accumulates slowly over time. It comes from the routine, everyday remarks that feel harmless in the moment but, when added together, create a cold or unwelcoming atmosphere. A major reason this happens is that the digital world hides the consequences of our words. Unlike a face-to-face conversation where you can see a friend's face fall or hear a sharp intake of breath, an online comment disappears into a void. The person who typed it rarely sees the effect of their words, and the distance between the action and the result feels too large to matter. This disconnect, combined with a lack of awareness that small, repeated actions build up into a larger pattern, allows negative environments to grow without anyone realizing they are the ones watering the garden.
Researchers at the Daegu Gyeongbuk Institute of Science and Technology set out to test whether making these invisible consequences visible could change how people speak online. They built a simple, browser-based tool that turned a user's commenting history into a living, growing virtual tree. The system did not block anyone from posting, nor did it issue warnings or punishments. Instead, it acted as a mirror. As users typed comments on social media, the tool analyzed the tone of their words. If the words were supportive or kind, the tree received a drop of water, helping it grow taller and healthier. If the words were hostile or toxic, the tree received a drop of poison, causing it to wither or stop growing. The goal was to shrink the psychological distance between the user and the impact of their behavior, turning an abstract concept into something concrete and immediate that could be seen every time they logged in.
To see if this approach worked, the team recruited fifty active social media users and asked them to use the tool for seven weeks. These participants were required to post at least seven comments a week, ensuring they were active enough to generate meaningful data. Over the course of the study, the researchers watched how the users' language changed. The results showed a clear shift in the type of words people chose. At the start of the study, only about thirty-eight percent of the comments were positive. By the end of the seven weeks, that number had climbed to nearly sixty-seven percent. At the same time, the number of neutral, non-committal comments dropped significantly, falling from roughly fifty-five percent down to thirty percent. The few negative comments that did appear remained low throughout the entire period, suggesting that the intervention did not necessarily stop people from being mean, but rather encouraged them to be more positive or to stop being indifferent.
The data also revealed how the virtual tree itself changed. The system tracked "water drops" and "poison drops" as a way to measure the balance of feedback. While the amount of water given to the tree did not change much from week to week, the amount of poison dropped sharply over time. This meant that the ratio of positive to negative feedback grew steadily, moving from a balance of roughly three to one at the beginning, to a ratio of more than forty-five to one by the final week. The tree, which started as a small sapling, grew into a robust symbol of the group's collective shift toward kindness. This visual change was not just a number on a screen; it represented a real transformation in how the participants expressed themselves, moving away from vague or neutral statements toward more constructive and encouraging language.
After the seven weeks ended, the researchers asked the participants how they felt about the experience. Thirty-seven people filled out a survey, and their answers painted a picture of heightened awareness. Most agreed that the visualization made the consequences of their comments feel more real and immediate. They reported that they were more conscious of the tone they used and that the tree influenced their choices. Some admitted they would delete a comment if they saw it turn the tree slightly sick, or they would add a few nice words to give the tree a boost of water. However, the study also noted that not everyone felt the same way. A small number of participants said they felt watched or monitored, worrying that their honesty might hurt the tree. This suggests that while the tool worked for many, it also introduced a sense of being evaluated, which can be a double-edged sword.
The researchers were careful to explain that their study was an observation, not a final proof that the tree caused the change. Because there was no control group of people who did not use the tool, it is possible that the participants simply changed their behavior because they knew they were being studied, a phenomenon known as the Hawthorne effect. They might have felt a pressure to perform well or to look good, rather than feeling a genuine internal shift in their values. The study also noted that the participants started with very few negative comments, so the tool might have been more effective at encouraging positivity than at stopping aggression. Despite these limitations, the findings offer a compelling glimpse into how a persistent, visual reminder can reshape the way people interact online. By turning the invisible weight of our words into a visible, growing thing, the system helped users see the cumulative power of their daily choices, suggesting that the right kind of feedback can nudge a community toward a healthier, more supportive future.
