Here's the source code for this analysis to those interested: https://github.com/joshdavham/cij-analysis

I will note that the transcripts (and parsing scripts) are not included in the repo. The transcripts are not my intellectual property so I can't share it (and the parsing scripts are a bit of a dumpster fire).

That's exactly right.

Much of the beginner videos make use of visual hints like you say (images, props, etc), and none of these were taken into account in my analysis.

I do think it could be cool to do a 'visual' analysis of CI in the future where you attempt to measure how much context is present (or not) in each video and see what insights you could draw from that.

That’s a good point.

I don’t think the ‘longer equals harder’ pattern holds for every language. I actually reached out to the head teacher at CIJ when I first made this analysis and she said the same.

Thanks for the kind words!

Oh wow! I’m surprised to see someone post my analysis haha

Happy to answer any questions here. I kept my analysis really high level for a general audience but since this is HN, we can get a bit nerdy :D
