1/ U Mich Prof Walter Mebane did a statistical analysis of S Korean's Nat'l Ass'y election & finds that fraud may have changed some results.

Friends have asked me what I think. I don't know enough to believe it, but I also know too much to dismiss it.
2/ The paper is only 14 pages long. Mebane has done statistical analyses of other elections, finding evidence of fraud in some cases & not in others.

3/ Based solely on his statistical modeling, Mebane concludes that 10.43% of the ruling Democratic Party votes were fraudulent. That's ... a lot.

He also concedes the possibility of benign explanations, & the limits of relying on statistical analysis alone.
4/ I'm the first to admit that I don't understand statistics well enough to understand Mebane's methodology or conclusions. Here's video of Mebane explaining it.


He seems qualified, credible & sane, but I'd appreciate other views from statisticians.
6/ I'd also expect opposition voters to be *more* energized to turn out in a non-presidential election, especially with the economy in a freefall before COVID-19 hit.

Polls last year showed that the ruling party had lost much support from young voters who supported it in 2017.
7/ What could legitimately explain this sudden shift?

By the time of the election, an effective response to the pandemic had overcome a lot of bad press from the govt's failure to prevent it in the 1st place.

It's still hard to believe this was such a strong net positive.
8/ What observed behavior supports allegations of fraud? I've seen claims of ballot tampering, but not enough independent analysis to draw conclusions. https://twitter.com/AuthorJCha/status/1259345488521748480?s=20
9/ Ideally, any persuasive analysis should be informed by an understanding of statistics, polling, voting demographics, & S Korean voting procedures.

Extraordinary claims require extraordinary evidence.
11/ That not only disentitles the Moon admin to a presumption of good faith, it undermines my confidence that journalists would investigate credible allegations.

Not knowing if elections are fair, gov't is honest, or the press is objective is a bad place for any democracy to be.
