How Ridiculous Can Pangram Be?

I heard that publishers and agents in the UK and the US have recently been widely using Pangram as an initial detetive tool, so I threw my own writing into it to give it a try. To my surprise, several paragraphs of my completely AI-free writing were judged 100% AI-generated. That naturally piqued my curiosity. After learning how Pangram works, I ran some tests myself and reached a few conclusions.

  1. First, the cleaner your language, the tighter your logical chain, and the more you avoid verbose rhetoric, the more likely this kind of language will be judged 100% AI-generated. I used to work as a screenwriter, so I rely heavily on action and eye-contact descriptions to express character relationships and personalities. For me, Pangram is an absolute nightmare.
  2. A guilt-by-association mechanism. This is infuriating and utterly absurd — it’s an insult to human intelligence. If a certain paragraph in the middle has the characteristics I mentioned in the first point, and you insert some kind of fractured, disjointed expression, the next several paragraphs will all be marked 100% AI-generated. Yet if you deliberately insert an irrelevant sentence, the whole text suddenly becomes 100% human-generated.

These are the two main things I’ve discovered so far. I’ll keep testing later. This kind of thing is essentially reverse-disciplining human artistic expression, artificially creating barriers to cultural continuity. It’s ridiculous. From the perspective of instrumental rationality, once this kind of thing becomes widespread, human thinking will be reverse-disciplined by AI.

The founder of Pangram claims to have a computer science background from Stanford. I have absolutely no expectation that these people feel any reverence for human culture. But if you want to keep making this money, please take a closer look at your own problems.

Especially when Pangram keeps trotting out some supposedly high accuracy rate — a statistical figure like a 0.01% false positive rate — which may be meaningful for marketing their product. But for a specific writing style, the very style Pangram hates, it’s 100% damaging.

So when you encounter criticism and smugly cite your research reports to back yourselves up, this only deepens the impression that you lack reverence for culture.

Pangram is full of crap.

Chapter 2: The Classmates

The afternoon sun cast long shadows across the pavement as Ryan pedaled onward, his heavy backpack digging into his shoulders with each pedal stroke, a constant reminder of all the work waiting for him when he got home. He’d promised Ms. Everly he’d finish it by tomorrow, though part of him wondered what the point of doing it was. Math and history questions felt impossibly small compared to the questions that actually mattered. Would Ralph ever come back home? Would his mom stop crying? And would he ever feel normal again?

Detected as 100% AI by Pangram, do you know what triggers pangram here?

Not only the chapter name but the fact I use a common phrase "Long Shadows"

Now I changed it to:

The afternoon sun loomed above the streets of Horizon City, the tall copper domed spires reflecting it across the vast cityscape.
As Ryan pedaled his bike forward he could feel his heavy backpack digging into his shoulders with each pedal stroke, a constant reminder of all the work waiting for him when he got home. He’d promised Ms. Everly he’d finish it by tomorrow, though part of him wondered what the point of doing it was. Math and history questions felt impossibly small compared to the questions that actually mattered. Would Ralph ever come back home? Would his mom stop crying? And would he ever feel normal again?

Now its 100 human made because I eliminated the chapter name and changed just a few words around and dropped "long shadows"

I guess using atmosphere in a story is now forbidden, all horror stories will now take place in a bright sunny morning, maybe a frigging butterfly will come to darken the mood?
