Researchers at Yale University identified 6 distinct groups of people, based on their beliefs about environment and climate change, policy preferences, values, needs, and corresponding behavior. Segments (Alarmed, Concerned, Cautious, Unconcerned, Doubtful, and Dismissive) were identified by means of latent class analysis, and profiled with regard to demographics, religious affiliation, media consumption and preferences, and civic engagement.
