Can GPT-4 Models Detect Misleading Visualizations?
This addresses the problem of visual misinformation online, particularly during critical events, but is incremental as it applies existing models to a new task with prompt engineering.
The study investigated whether GPT-4 models can detect misleading visualizations, finding they achieve moderate accuracy in naive zero-shot settings and improve with guided prompts, though effectiveness varies by misleader type.
The proliferation of misleading visualizations online, particularly during critical events like public health crises and elections, poses a significant risk. This study investigates the capability of GPT-4 models (4V, 4o, and 4o mini) to detect misleading visualizations. Utilizing a dataset of tweet-visualization pairs containing various visual misleaders, we test these models under four experimental conditions with different levels of guidance. We show that GPT-4 models can detect misleading visualizations with moderate accuracy without prior training (naive zero-shot) and that performance notably improves when provided with definitions of misleaders (guided zero-shot). However, a single prompt engineering technique does not yield the best results for all misleader types. Specifically, providing the models with misleader definitions and examples (guided few-shot) proves more effective for reasoning misleaders, while guided zero-shot performs better for design misleaders. This study underscores the feasibility of using large vision-language models to detect visual misinformation and the importance of prompt engineering for optimized detection accuracy.
