I wish I had the full scientific background to fully interpret this interesting new study, because the results have HUGE implications in psychology, but as far as I know are not particularly surprising or at odds with related research. The genetic and phenotypic independence of face recognition ability would smash to smithereens the long-debated idea of “g”, or one (mysterious) factor largely determining general mental ability. Face recognition or face memory appears to defy “g”, but all the same, I can’t help clinging to the idea that there’s a link between top ability in face recognition and at least some other cognitive gifts. Based on personal experience I find it hard to leave behind the idea of a link between elite reading and writing ability, synaesthesia and superior face recognition.
Placing the heritability of face recognition ability at 61%, as this study has done, kicks sand in the face of the long and bitterly debated idea that giftedness or talent is the result of long hours of focused training rather than innate ability, but I can think of one researcher who has championed the “trained not innate” position on talent or expertise for many years, who seems to lack an awareness of the entire body of face recognition research, instead focusing his attentions on elite performers in sport, music, memory and chess. Ignorance is bliss, they say.
I am a super-recognizer, and I have no memory of ever training my ability in recognizing or memorizing faces, and no one has coached, pressured nor trained me to this specific task. I defy those who argue that intelligence is “environment” not genetics to explain me and faces. Up until a few years ago I had no idea I was even above average with faces, so don’t ask me.
