Repetition increases belief in climate-skeptical claims, even for climate science endorsers

Fig 2. Estimated mean truth ratings across repetition (repeated, non-repeated) and claim type (science-aligning, skeptic-aligning) in Experiment 2. Note. Error bars show 95% CI. https://doi.org/10.1371/journal.pone.0307294.g002 Table 3. Effect size calculations of the repetition effect across claim type in each Experiment.
