Research in human subjects must always involve obtaining informed consent. In obtaining informed consent it must involve: letting the participants know that participation is voluntary, obtaining the participants signature or a signature from the parent or guardian if the participant is a minor and reviewing that data is confidential. In addition, an clinical case study is conducted by gathering detailed information about participants who are psychological patients. Institutional review board reviews research that is led by means of human members. The scientific process is cyclical, connecting together inductive and deductive cognitive. Ethic needs to be measured when designing, conducting and go over scientific research.
