Peer review, through discussion and debate within journals and conferences, assists in this objectivity by maintaining the quality of research methodology and interpretation of results.
[2] Though there were a few older societies of men who studied nature such as the Royal Society of London, the concept of scientific communities emerged in the second half of the 19th century, not before, because it was in this century that the language of modern science emerged, the professionalization of science occurred, specialized institutions were created, and the specialization of scientific disciplines and fields occurred.
Unlike in previous centuries when the community of scholars were all members of few learned societies and similar institutions, there are no singular bodies or individuals which can be said today to speak for all science or all scientists.
For example, the United States' National Academy of Sciences (NAS) and United Kingdom's Royal Society sometimes act as surrogates when the opinions of the scientific community need to be ascertained by policy makers or the national government, but the statements of the National Academy of Science or the Royal Society are not binding on scientists nor do they necessarily reflect the opinions of every scientist in a given community since membership is often exclusive, their commissions are explicitly focused on serving their governments, and they have never "shown systematic interest in what rank-and-file scientists think about scientific matters".
[9][10] It is very unusual for organizations like the National Academy of Science to engage in external research projects since they normally focus on preparing scientific reports for government agencies.
In response to this some non-consensus claims skeptical organizations, not research institutions, have devoted considerable amounts of time and money contesting ideas which run counter to general agreement on a particular topic.
An alleged conflict thesis proposed in the 19th century between religion and science has been cited by some as representative of a struggle between tradition and substantial change and faith and reason.
Galileo had used arguments from the Pope and put them in the voice of the simpleton in the work "Dialogue Concerning the Two Chief World Systems" which caused great offense to him.
In more recent times, the creation–evolution controversy has resulted in many religious believers in a supernatural creation to challenge some naturalistic assumptions that have been proposed in some of the branches of scientific fields such as evolutionary biology, geology, and astronomy.
Mass protests in the United States and Europe during the 1970s and 1980s along with the disasters of Chernobyl and Three Mile Island led to a decline in nuclear power plant construction.
