Data from Experiment 2a in Spicer et al. (2022)
Description
Cognitive judgments. Participants answered questions about commonly experienced values. Unlike in Experiment 2, participants viewed each question multiple times, comparing each against both a low (25.5) and high (75.5) comparison value to create 40 trial cases. As in Experiment 1, decisions were requested on all trials, but only 30% of trials were randomly selected to include a direct estimate.

- Trial
Trial ID based on order of presentation
- QID
ID for the target question of that trial. Note that these IDs match those of the calibration data.
- Question
