A morbid curiosity exemplifies addictive curiosity. It has as its object death, violence, or any other event that may cause harm physically or emotionally, the addictive emotion being explainable by meta-emotions exercising pressure on the spontaneous curiosity itself.[citation needed] According to Aristotle in his Poetics we even "enjoy contemplating the most precise images of things whose sight is painful to us". (This aspect of our nature, often referred to as the "Car Crash Syndrome" or "Trainwreck Syndrome", accounts for the supposed attraction such accidents have for passers-by.)
