The category with the least amount of comments per thread, CRISPR, had the lowest Yule I increase over time. The category with the second least amount of comments per thread, Vaccines, had the second least increase. However, Vaccine threads had almost 300% higher comments per thread than CRISPR but only a 25% higher score increase rate. I do not know the reasons for this.
When not looking at aggregates, there was a large range of both comment levels and Yule I score levels. For one of the Vaccine threads, the Yule I score decreased by a rate of 197.32 per day while another thread in the same category showed a 101.47 increase per day. The thread with the most comments and highest Yule I score, “EPA chief Scott Pruitt says carbon dioxide is not a primary contributor to global warming” had a whopping 9636 comments and an average daily Yule I increase of 356.80. The link between comments and Yule I rates is visible after a cursory glance of the results table (below), but to find out these results are significant, I ran a significance test.
