Design and procedures

Experiment 2 presented participants with two different factions within the climate movement. Otherwise, the study was very similar to experiment 1 with a few exceptions. In addition to the larger sample, we included a number of improved measures (see SI for all manipulations and measures).

Like experiment 1, experiment 2 was a 2 × 2 between-subjects design with similar instructions. Each participant was exposed to two factions within the climate movement, a treatment faction (called “Climate Action Today”) and a focal faction (“Global Warming Warning”). The description of the focal faction’s agenda and tactics were held constant, but the treatment faction’s agenda and tactics were manipulated independently.
