Subclaims¶

q2 i? No group was significantly more or less likely to change their opinion about climate change after viewing comedy versus IPCC videos. → Carter 2016

Evidence¶

Carter 2016¶

Carter, B. E., and Wiles, J. R. (2016). Comparing effects of comedic and authoritative video presentations on student knowledge and attitudes about climate change. Bioscene, 42(1), 16-24. https://eric.ed.gov/?id=EJ1103782

q2 · i? · causal · r1

Quasi-experiment in two sections of a large mixed-majors introductory biology class; one section viewed IPCC films, the other comedy clips, with a no-video Control group compared on pre/post surveys. The article reports "little difference was observed" and no significant group differences in opinion change.

"Despite our expectations about differential effects between IPCC and Comedy videos, little difference was observed. No group was significantly more or less likely to change their opinion about climate change."

• Measured climate science knowledge significantly decreased pre- to post-intervention in all three groups, including controls — related
• Students perceived authoritative IPCC videos as more likely to influence voting than comedic videos — related
• PBL shifts learners' opinions about topics modestly, and learners with strong pre-existing opinions are less likely to change — a broader claim this one bears on
