Derek Parfit was a 5:
> He has few memories of his past, and he almost never thinks about it, although his memory for other things is very good. He attributes this to his inability to form mental images. Although he recognizes familiar things when he sees them, he cannot call up images of them afterward in his head: he cannot visualize even so simple an image as a flag; he cannot, when he is away, recall his wife’s face. (This condition is rare but not unheard of; it has been proposed that it is more common in people who think in abstractions.) He has always believed that this is why he never thinks about his childhood. He imagines other people, in quiet moments, playing their memories in their heads like wonderful old movies, whereas his few memories are stored as propositions, as sentences, with none of the vividness of a picture. But, when it is suggested to him that an absence of images does not really explain an absence of emotional connection to his past, he concedes that this is so.
All of the people saying 5’s are low IQ are just coping lmao
