Much of the knowledge we consider to be accurate facts today is likely to be exchanged for new facts in the future. In history, knowledge is considered a historical fact. In the humanities, knowledge refers to scientific discoveries considered scientific laws, theories, and behaviors. Over time, more and more research and analysis is conducted in history and the humanities to ensure that the knowledge we "accept" today is accurate and correct in every detail. If experts in each field, such as psychologists or historians, find flaws in the "accepted knowledge" in their field of knowledge, they will decipher whether the faulty knowledge should be totally rejected and replaced with new facts that are supported by evidence to be more precise. Flaws in knowledge can be revealed by scientific discoveries in the humanities or by the discovery of new and authentic primary sources in history. The knowledge questions that will be explored in relation to history are: "To what extent does historical knowledge need revision?" " and "How could the manipulation of revisionist history prevent us from acquiring accurate knowledge? The knowledge question to explore in the humanities is: “Are there any theories or laws in the humanities that have stood the test of time?” I believe that, to some extent, history needs revision to ensure the accuracy of historical knowledge is maintained, but revisionist history can be easily manipulated. I also believe that to deepen our knowledge in the humanities, we need to experiment with trial and error regarding psychological theories. Revisionist history is not extremely common, but it is certainly not rare. History is revised when researchers find inconsistencies or ...... middle of article ....... The more time given to us in the future will allow historians and psychologists to s engage in more scientific research and analysis to ensure that what we accept is that correct facts are retained while knowledge and facts that have been proven to be false or inaccurate are discarded. There are dangers of manipulation when it comes to revisionist history, but with proper oversight, revisionist history ensures that the accuracy of our historical knowledge is maintained. We must use the history revision approach with extreme caution and skepticism. The humanities have had their share of correct theories and disproven theories, but disproved theories have also advanced knowledge in the humanities since new discoveries were quickly superseded, such as how genetic influence replaced the blank slate theory. We must learn from our mistakes in order to redirect our approach towards the discovery of precise knowledge.
