Although the SICP is an awful book, the thing in section 1.1.1 that OP refers to where it presents formatting an expression:

  (+ (* 3
        (+ (* 2 4)
           (+ 3 5)))
     (+ (- 10 7)
        6))

is a decent point.

I mean, how could they present this differently? Pretty much any Lisp book should explain this stuff the same way. Look, we have these parentheses and that's what the machine cares about, but we split across and indent like this.

If someone finds that reformatting to be incomprehensible and unreadable, virtually no different from the original one liner, they may have some cognitive issue (a form of dyslexia or something like it). Likely they will struggle with programming in any language.

I don't suspect it's "cognitively typical" not to find the visual structure of the above formatting to be obviously helpful.
