Please join AAAS for a lecture by Paul Offit on communicating science to the public. We have moved from scientific illiteracy to science denialism. Today, people simply declare their own truths: vaccines cause autism; climate change isn’t real; evolution and creationism are equally valid hypotheses. As a consequence, science is losing its rightful place as a source of truth. Scientists are in the best position to combat this growing trend. However, those who choose to explain science to the press and the public face many challenges. The AAAS will discuss some of those challenges and offer suggestions on how best to deal with them.
