Intellectual pollution is dangerous for societies as it distorts their members' principles, values, ideas, and beliefs which negatively influences their behavior, undermines society's cohesion, and increases the qualitative and quantitative motives of the criminal phenomenon. Thus, this research addresses the issue of intellectual pollution and its impact on crime using an inductive and analytical approach. The paper discusses the topic in two sections; the first is the nature of intellectualpollution, and the second is its effects on the criminal phenomenon. This paper obtained significant conclusions, one of which was intellectual pollution is every extraneous thought, belief, or tendency to the original values that can be translated by criminal behavior that negatively contradicts a society's identity and constants. Another interesting conclusion was intellectual pollution is embodied in many forms, the most dangerous of which is what leads to extremism and hyperbole accompanied by violent actions.
