Figure S1 - Lifting the Veil of Morality: Choice Blindness and Attitude Reversals on a Self-Transforming Survey

Sample verbal reports from undetected manipulated trials in relation to the principle of harming the innocent, and the issue of governmental surveillance of e-mail and Internet traffic (all reports have been translated from Swedish, and transcription notation has been removed for ease of reading). Participants were presented with either an abstract principle or concrete moral issue, and then asked to indicate their attitude towards these on a scale from 1 (completely disagrees) to 9 (completely agrees). The figure in each cell of the table (a-h) shows the original rating of the participants as a filled red hexagon on the scale. In a manipulation trial, participants then face a negated principle or issue, which is the equivalent of moving their original rating to the mirror side of the scale. This dynamic is shown as a dotted red line ending in a X-marked hexagon in the figure. The verbal report the participants give at this point is shown in a speech bubble originating below the X-mark. Looking at the verbal reports it is evident that they present a much better fit to the manipulated side of the scale (the red X), than the original position (the red filling). This is further confirmed by the blue dot, which represents the attitude position the independent raters deemed most appropriate for the same report, when evaluated with no knowledge of the original position. Here, it can be seen that the blue dot consistently is placed on the same side of the scale as the red X, and much closer to it than to the original red filling.

本数据集收录与伤害无辜者原则、政府电子邮件及互联网流量监控议题相关的未被察觉操纵实验的口头报告。所有报告均由瑞典语译出，且为便于阅读已移除转录标注。实验过程中，参与者将被呈现抽象原则或具体道德议题，随后需在1（完全反对）至9（完全同意）的态度量表上表明自身对此的态度。表格（a至h）的每个单元格对应的可视化图中，参与者的原始评分以量表上的实心红色六边形表示。在操纵实验阶段，参与者将接触到被否定后的原则或议题，这相当于将其原始评分移动至量表的镜像侧。该变化过程在图中以一条红色虚线呈现，虚线末端为带有叉号标记的六边形。参与者在此阶段提交的口头报告，将以源自该叉号标记下方的对话气泡形式展示。观察这些口头报告可明显发现，相较于原始评分位置（红色实心六边形），报告内容与量表操纵侧（红色叉号标记六边形）的契合度显著更高。该结论可通过蓝色圆点进一步验证：蓝色圆点代表独立评分者在未获知原始评分位置的前提下，认为与该口头报告最匹配的态度立场。结果显示，蓝色圆点始终与红色叉号标记处于量表的同一侧，且相较于原始红色实心六边形，其与红色叉号标记的距离更近。(PDF)
