Scientists have ethical traditions.
Scientists are influenced by societal, cultural, and personal beliefs and ways of viewing the world. Scientific explanations must meet certain criteria. Because all scientific ideas depend on experimental and observational confirmation, all scientific knowledge is, in principle, subject to change as new evidence becomes available. Usually, changes in science occur as small modifications in extant knowledge. Occasionally, there are advances in science and technology that have important and long-lasting effects on science and society.
