So, what are the traits of these mutable signs? Well, they’re known to be adaptable and frantically indecisive. And they’re perfectionists so no stone is left unturned.” You know they’re bleaching those crime scenes within an inch of their lives. “You know their crime scenes are immaculate though. More recently, in October 2022, TikToker Lauren Elaine Skirvin made a viral TikTok about that same stat. (For comparison, cardinal signs fall at the beginning of a season and fixed signs fall in the middle of a season-and both have personality traits to match.) Back in 2008, a Dutch statistician named Jan Ruis, PhD, looked at the birth charts of almost 300 serial killers and found that “serial killers are frequently born when celestial factors are in mutable signs.” Gemini, Virgo, Sagittarius, and Pisces are known as mutable signs, meaning their signs fall at the end of a season (Gemini falls at the end of spring, Virgo at the end of summer, Sagittarius at the end of fall, and Pisces at the end of winter). And it turns out, a sign’s modality has a little something to do with…murder. Each sign is either a fixed sign, mutable sign, or cardinal sign, and each of these modalities has a different set of personality traits that go along with it.

You know how the FBI has an entire team dedicated to psychologically profiling murderers? Well, maybe they should just use astrology instead.
