Add representational images illustrating actual vs. estimated proportions
E.g., if the prompt is "What is been the percentage change of global ice coverage since 1970" we might show a estimated global ice coverage in 1970, and on answer evaluation show two different images, one with the actual current coverage, and one with the amount of coverage predicted by the participant.
This is quite involved, since each question will its own dynamic graphic. This is almost certainly unachievable in the first iteration of this intervention, but something that should be within reach with more funding and a longer horizon.
