The term "junk science" refers to scientific research or data that is considered to be flawed, misleading, or incorrect. It often involves manipulation or distortion of facts, statistics, or evidence to support a particular agenda or belief, rather than being based on sound scientific methods and principles. The phrase is used to describe studies or claims that are not supported by reliable data or research methodology, and which may be influenced by personal or political motives. In essence, "junk science" represents a misuse of scientific knowledge for self-serving purposes, rather than being based on objective truths and evidence-based conclusions.
