From fictional serial killers such as Hannibal Lecter and Dexter Morgan to real-life murderers Jack the Ripper and the Zodiac Killer, people have probably become equally terrified and fascinated with these characters. In the case of the fictitious, they are both considered highly intelligent, with flashes of ingenuity, but in the case of the other two, we can only speculate. While there have been real serial killers who have registered high IQ scores, a study has shown that the average IQ of serial killers are in fact, average. In the case of the Green River Killer, Gary Ridgway, he was reported to have a low IQ but he went on to sow terror for two decades before getting caught, claiming more victims than those who were said to be at genius level, such as Rodney Alcala, or The Dating Game Killer.
