反射地震资料的解释人员通常使用图像来传播他们的地质解释工作的结果。这种解译图像的呈现可能会在观察者的感知中产生不必要的偏见，这种效应被称为“框定偏见”。这些框架偏差可以增强或降低观察者对所给解释的置信度，而与地震数据或地质解释的质量无关。我们测试了在线实验的761名参与者的陈述对口译信心的影响。实验参与者看到了地震图像和解释，并在不同方面进行了刻意修改，以引入潜在的框架偏差。对结果的统计分析表明，与地震数据和解释的质量相比，图像呈现对参与者信心的影响较小。结果使我们能够提出建议，以尽量减少观察员在介绍地震解释方面的偏差：(1)解释应与背景中的地震数据一起显示，以便于未解释的解释数据与随后的置信度评估之间的比较；(2)解释中以颜色辅助显示的地震数据，尽管必须仔细选择调色板，以防止观察员因共同的颜色光谱而产生不必要的偏见；以及(3)解释人员在他们自己的解释中明确表示不确定性，参与者认为这是有用的。
Interpreters of reflection seismic data generally use images to disseminate the outcomes of their geologic interpretation work. The presentation of such interpretation images can generate unwanted biases in the perception of the observers, an effect known as "framing bias." These framing biases can enhance or reduce the confidence of the observer in the presented interpretation, independently of the quality of the seismic data or the geologic interpretation. We have tested the effect of presentation on confidence in interpretation of 761 participants of an online experiment. Experiment participants were presented with seismic images and interpretations, deliberately modified in different aspects to introduce potential framing biases. Statistical analysis of the results indicates that the image presentation had a subdued effect on participants' confidence compared with the quality of the seismic data and interpretation. The results allow us to propose recommendations to minimize biases in the observers related to the presentation of seismic interpretations: (1) interpretations should be shown with the seismic data in the background to ease comparison between the uninterpreted-interpreted data and the subsequent confidence assessments; (2) seismic data displayed in color aids in the interpretation, although the color palettes must be carefully chosen to prevent unwanted bias from common color spectrum in the observers; and (3) explicit indication of uncertainty by the interpreters in their own interpretation, which was deemed useful by the participants.
