Remove nonessential realism from analytic visualizations

Remove realistic detail that is not part of the decision task. For example, use a simpler map or schematic scientific image instead of a highly realistic or 3D rendering when readers need to judge relative position, compare values, or make an analytic inference.

Detailed, realistic imagery attracts attention and can make the display feel more authoritative, even when the extra detail does not help the task. Readers may prefer the realistic version, but that preference can come with slower performance and attention to irrelevant features.

Mechanism: Realistic detail and high-production styling increase perceived credibility and pull attention toward visually rich but task-irrelevant elements.

Evidence: The review reports that high-quality or realistic images can increase perceived scientific credibility while harming performance relative to simpler displays, including realistically depicted maps that drew attention to irrelevant information and slowed users (Padilla et al., 2018).

• User Goal: Make an analytic judgment from a visual display.
• Task: Compare, locate, or infer from displayed information rather than inspect appearance itself.
• Data: Maps or scientific visuals with optional realistic texture, shading, or 3D rendering.
• Chart Setting: A more schematic alternative is available without removing task-relevant information.
• Audience: Novices or experts making task-focused judgments.
• Success Criterion: Faster and more accurate judgments with less distraction and less credibility bias.

Break it when: The realistic detail itself is what readers must inspect. Why: The source problem is nonessential detail pulling attention away from the task, not the mere presence of detail.

Sacrifice: The display may look less impressive or less preferred. Risk: Readers may initially favor the richer-looking version even when it performs worse. Mitigation: Remove only detail that is not needed for the task.

Mistake: Add 3D rendering or realistic texture to make the display look more scientific or engaging. Why it fails: Readers may trust the display more while actually performing the task worse.

Failure Sign: Readers prefer or trust the more realistic version but answer slower or attend to irrelevant regions. Quick Check: Compare a realistic version and a simpler version on the same task and keep the one that yields better task performance. Stronger Test: Observe whether attention concentrates on decorative or background detail instead of the information needed for the decision.

• Remove realistic textures, shading, or 3D treatment that do not encode task-relevant information.
• Replace a realistic view with a simpler schematic or less realistic map when the task is analytic comparison.
• Keep only the visual detail that readers must inspect to answer the task.
