Investment in research or in scientific activity is ultimately a community decision, supported by public funds. Scientists, therefore, have the responsibility and the moral obligation of accurately communicating their ideas and results to the public. Of necessity, some of this can be restricted to an audience of peers, but it is essential to communicate the results of publicly funded research to a wider audience. Scientists and communicators of science share the additional responsibility of responding to fallacious and misleading statements on issues pertaining to science that are made by persons holding public office and those who play a prominent role in society.
