Serial killers often start their criminal paths in adolescence or early adulthood, with many beginning with lesser crimes like animal cruelty or arson before escalating, though the average age for a first murder is around the mid-20s (around 27-28), with the peak age for their criminal careers often cited between 25 and 35, though some start much younger, like Ed Kemper, who killed grandparents at 15 before later murders.
Jeking (1988) concluded that most start their careers between the ages of 24 and 40. The median age of arrested serial murderer is 36 (Bartol, 1995). In a study of 217 American serial murderers, canteret.al. (1996) found that 75% had previous convictions and nearly half had been arrested as juveniles.
In classifying types of serial murder, the factors discussed are behavioral background, victim profiles, methods used, and location of the murders. Four types of serial murderers are identified: the 'visionary,' the 'mission-oriented,' 'hedonistic,' and 'power/control-oriented.
Studies have suggested that serial killers generally have an average or low-average IQ, although they are often described, and perceived, as possessing IQs in the above-average range. A sample of 202 IQs of serial killers had a median IQ of 89.
3,013 murderers in the United States in 2023 were individuals between the ages of 20 and 24. In the same year, there were seven murderer offenders aged between one and four years.

Snoop Dogg has publicly stated he has an IQ of 147, a score that falls into the "highly gifted" or "genius" category, much to his own surprise given his self-described average school performance (straight Cs).

No, an IQ of 97 is not considered dumb; it falls squarely in the average range (90-109), indicating typical cognitive abilities, though some tests might place it slightly below the exact midpoint of 100. An IQ score of 97 means you performed better than 42% of people, and due to the test's margin of error, your score could be anywhere from the high 80s to the mid-100s, still within normal intelligence.
Lady Gaga's IQ is widely rumored to be around 166, placing her in the "exceptionally gifted" or genius category, though this is an estimation often cited in celebrity lists, not a officially verified number from a public test.
