The purpose of AITSE is to promote good science, based on impartial evaluation of evidence, not mere consensus. The purpose of NCSE is to promote the consensus view on evolution and squash any hint of dissension—no impartial evaluation of evidence allowed. As such, there is really no commonality between our goals. The only possible similarity between AITSE and NCSE would be in our mutual focus on education. But, again, NCSE has a very narrow educational focus since they want to educate on one subject and on only one point of view about that issue. In comparison, AITSE encourages people to think about the scientific evidence on a range of topics. We have solicited input from scientists, physicians and engineers coming from a variety of viewpoints on controversial matters—not that all actually contribute. But, since scientific integrity requires telling the whole story, our doors are open. Our goal is for the evidence to be evaluated, not to fit scientific evidence into a prior worldview which, in the case of NCSE’s president Eugenie Scott, is humanistic naturalism.
One of the first things we need to point out to new kids on the block is that “National Center for Science Education” is not in any way about science education as such, it is about forcing Darwinism, explicitly and exclusively, on the school system. They even oppose teaching other non-design approaches to evolution, as shown here. (They may be planning to join in the climate change din.)
