Scientists throughout the ages have helped human society progress by building up our understanding of the natural world through observations, tests, and analysis. They have also done much to advance our collective cause when outside the lab in order to engage with policy debates that are relevant to their fields of study. AAAS scientists agree, with nearly 9 in 10 saying that scientists should not simply be confined to a lab, but should take an active, public role in discussing the ramifications of their work.
