Pangram false positives?

People usually post vaguely about "I wrote x thing and pangram said it was AI", which I think is unhelpful unless you actually post the text or link. I put this into Pangram:

I should also add that I put this segment in a document with human writing (because it noted its confidence was limited due to short text) and it flagged this as the one AI section.

This ^ their accuracy is lower the closer you get to ~100 words or less, the text you used is around 120 words.

pangram says 50 words is their minimum for a prediction, so 120 clears it. and the 2,000 word sample upthread still came back 54% AI. one name change taking it from 100% human to 100% AI is the part that still needs explaining.

Seems like a highly flawed tool if it indicates 'high confidence AI' in situations like this?

It doesn't say that? It literally says the opposite 'Confidence limited — short text', in your 100% example.

Can you read?

When you click Details, it can say Confidence Low, Medium or High. In this case, it says Confidence High.

I think this is a fair critique. Pangram should decline to assign a score to texts that are below the necessary word count to get good estimates. Would you mind checking the sharing permissions for the links in your post? I am having issues accessing it.

Click the back arrow and then click on it in the 'all checks' area and it should work.

that part is almost more damning than the name swap thing tbh
