Approximately 6 million Jews were killed by the German army during the Holocaust on the basis of racism and antisemitism, and millions were tortured, which had a negative and adverse effect on their mental conditions, so we can say that pseudoscientific ideas of race have an adverse effect on the Jewish nation. The pseudoscientific racism theory discovered prejudice based on factors such as people's culture, faith, and political views. There were anti-Semitic statutes enacted to discriminate against Jews, demonstrating how notions of racial negativity affected Jews.
These beliefs drove government policy in Germany after the Nazis took control. Hitler's racial theories have been generally condemned as wrong and immoral. As a consequence of Nazi prejudice,Six million Jews and millions of other people were persecuted and murdered as a consequence. The Nazis and Adolf Hitler thought that the world was split into different ethnicities.
Pseudo-scientific ideas about race were also used in the United States in the nineteenth century. Native Americans and African Americans were regarded as inferiors by the government, while Europeans were treated as superiors.
