Minorities of people express strong trust in scientists’ understanding of the causes of climate change (28%) or the health effects of eating GM foods (19%), saying that scientists understand these matters “very well.” About half of people (47%) say the same about medical scientists’ understanding of the health effects of the MMR vaccine.
At least four in 10 people say that scientists understand each of these matters “fairly well.” A sizable share of people are skeptical of climate scientists’ and GM food scientists’ understanding about the causes of climate change and the health effects of GM foods, respectively, saying that scientists understand these matters “not too well” or “not at all well.”
