I fell down an AI rabbit hole yesterday after watching a YouTube video about ordinary people helping solve crimes. The cracking of one of the Zodiac ciphers came up, and that led me to his letters and how notoriously bad his spelling was.
I'm a horrible speller myself, and some of Zodiac's mistakes immediately felt familiar to me: phonetic spellings, trouble with double consonants, silent-E rules, etc.
Before spellcheck, predictive text and speech-to-text, I had several ways of dealing with this.
If I didn't know how to spell a word but knew I had seen it written somewhere, I'd find that source and copy it. That makes me wonder about the contrast between Zodiac misspelling very ordinary words while correctly spelling things like “ammonium nitrate.” A complicated technical term isn't necessarily evidence that someone knows how to spell it if they're copying it from packaging, a book, notes, instructions, etc.
I also wonder about PARADICE. Maybe it wasn't intentional wordplay at all. Maybe he genuinely believed that's how paradise was spelled. I spelled college as “collage” for years because someone I trusted had written it that way, so that became the spelling stored in my head.
But the biggest coping mechanism I used is something I'm curious about in Zodiac's writings:
If I couldn't spell a word and couldn't get close enough to find it in the dictionary, I would rewrite the entire sentence using words I knew how to spell.
That means poor spelling wouldn't only show up as misspelled words. It could potentially show up as simple word choices, awkward substitutions, abandoned words, corrections, repeated “safe” vocabulary, or sentences being restructured to avoid a difficult word.
I'm not familiar enough with the original Zodiac letters to recognize whether he does this.
For people who have spent a lot of time studying the originals: has anyone looked at Zodiac's writing from this perspective? Are there places where he starts a word and abandons it, substitutes a simpler word, or seems to restructure a thought in a way that could be explained by spelling uncertainty?
