Original research
Hi again, Hingyun12. In this edit of 22:39, 26 July, you added numerous columns to the top life expectancy table in the article List of U.S. states and territories by life expectancy, including the "comparable country" column. Most of that edit was fine, including all the columns you added except the last one. However, the "comparable country" column is what we at Wikipedia call "Original research", and it is forbidden, so I removed that column (diff) along with an edit summary explaining why and linking to a discussion about it. Wikipedia's policy on Verifiability requires that all assertions in articles be verifiable, meaning that you could look it up in a reliable source like a published book, academic journal, or reliable magazine or newspaper. The column you added fails this test.

The reason the "comparable country" column was removed, it because it is a type of original research called "Synthesis of published material". Sorry to hit you so soon with this rather technical point that even experienced editors aren't always in command of. What it means, basically, is that there is no single reliable source that supports that content; that means that is it unverifiable and should be removed. For example, take row #1 from the table, labeled "Hawaii": this row is at the top of the table, because "Hawaii" is the state with the highest life expectancy of any U.S. state or territory in 2019. That is not sourced, but it's nevertheless fine because it could be sourced (I had no trouble finding sources for it, and if anyone challenges it, a citation would be required). After your edit, row #1 contains "New Zealand" in the last column, as a country that had a comparable life expectancy to Hawaii. I don't doubt the accuracy of this; it is probably true. The column header just above "New Zealand" cites Country Insights to support this. However, Hawaii does not appear on that page, although New Zealand does. In fact, as far as I can tell, there is no reliable source of any kind that compares Hawaii and New Zealand regarding life expectancy. Wikipedia cannot be the first to make an assertion, such as the Hawaii–New Zealand comparison; that must come first from one reliable source first, and after that, we can summarize it.

After I removed the column with the original research with an explanatory edit summary and a Talk link (here) you doubled down, and reinserted the offending content again (here). I just wanted you to know, that I've once again removed it. If you feel I have made a mistake, please raise a discussion on the article talk page, Talk:List of U.S. states and territories by life expectancy, where you can discuss why you think your content should be on the page, and attempt to achieve consensus from other editors. Please ping me there, if you do. Thanks, Mathglot (talk) 00:01, 6 August 2022 (UTC)
