“Ironically, I have a high IQ. I didn’t know that until I was locked up the first time for murder. I always thought I was little missin’ up here, a little short, because I was always called stupid, called slow.”ed kemper (from his 1991 interview with Stéphane Bourgoin)
At Atascadero, California Youth Authority psychiatrists recorded that Kemper had an IQ of 136 when he first was imprisoned there in 1964 following the murder of his grandparents. Later on in his time at Atascadero, Kemper tested higher at an IQ of 145.
In an interview published in the Fall of 2017 in the Daily Mail UK, after the release of the Mindhunter series on Netflix, Ed Kemper’s half-brother, David Weber, had this to say about Kemper’s IQ: ”Susan [Kemper’s older sister] told me once that Guy’s IQ [Guy is Ed Kemper’s nickname in his family] is far higher than the reported 146, more like 180 plus. He faked his IQ tests so it would always come out showing he had an IQ in the upper 140s. He’s a demented super-genius of a sociopath. He is incapable of caring regardless of what he says or shows. He makes OJ Simpson look like a rank amateur at best.”
During his 2017 parole hearing, Kemper seems to take pride in the fact that he has a high IQ and that it somehow makes him better than other people, as in this excerpt where Presiding Commissioner Fritz and Kemper discuss this topic:
Presiding Commissioner (PC) Fritz: Do you think you’re better than other people?
Kemper: Well, some people, I am. I don’t know how…
PC Fritz: You do think you’re better than other people?
Kemper: No, there are some people that – I have a high IQ, they don’t.
PC Fritz: So?
Kemper: Uh, well, I’m saying.
PC Fritz: I mean, so what. Lot – Tons of people in this room have high IQs. That doesn’t make us better than anybody, right?
Kemper: Not in…
PC Fritz: Does it make you feel good about yourself to say oh I have a high IQ so I’m better than other people?
PC Fritz: Okay so then what do you mean by you are better than other people besides having a high IQ?
Kemper: Some people, some of my acquaintances, uh, speak in, uh, a fashion that, uh, tells me they’re happy with much simpler accomplishments moment to moment, day to day, and I might put a lot more energy into that; a lot more effort into that than to so simply speak up to something. In that sense.
PC Fritz: Okay, all right. So you can’t empathize or be happy with the accomplishments they have cause you think they’re simple accomplishments versus your accomplishments.
