Experiment testing on whether accurate portrayal of scale in textual information, visual information, or both made a difference in participants’ understanding and perceptions of Carbon Capture and Storage (CCS). ECN Policy Studies and Cambridge University researchers developed a 3×3 experimental design study with 2 factors: (1) textual description, and (2) visualization of depth of CO2 interjection, and 9 conditions as supplementary information to a questionnaire. 473 UK adults participated (only 429 provided reliable results) in the experiment which was held online. Research results showed that it cannot be assumed that visual information will be interpreted correctly by participants, and that textual explanations are more effective in producing more accurate understandings and estimates of depth of CO2 interjection.
