Are you implying that the west is as corrupted as Japan? That is not something I can agree with.

In case you got yourself isolated from daily news for too long, below is just some recent news regarding those common practices in japanese labs.

https://en.wikipedia.org/wiki/Japanese_scientific_misconduct...

most japanese major groups are falsifying their various type of data - just look at recent news since 2015

Hitachi admitted falsifying data on brake testing https://www.asahi.com/ajw/articles/14508789

More fraudulent testing found in Mitsubishi Electric https://www.asahi.com/ajw/articles/14630514

Accounting fraud by Toshiba https://asia.nikkei.com/Business/Companies/Toshiba-s-chairma...

Sorry for the typo, statistically you make more typos when you write in a foreign language. feel free to make fun of it, totally fine with me.

If you cite Korean (or Chinese or Japanese) names, please write them correct. There is no Hyun-Tak Kim, he is called Kim Hyun-Tak. Likewise Kwon Young-Wan. In Korean it's trivial to detect, in Chinese not so, in Japanese very hard.

Ouch. This comment backfired quite badly. Turns out the person being replied to is Korean, the commenter is likely not, and in addition this is how the authors wrote their names themselves. Yet I do not wish this comment to be snarky. I’m interested in the broader perspective (and I apologize in advance to the parent for using this as an hook). The comment seems common of the present era in which polarization (leadin…

You never write cjk names with firstname first, always surname first. Japanese usually complain, the others just shake their heads silently about the silly westerners.

When the original author writes his/her name american style he/she moved to america, but then he/she changed his firstname also. In this case some citations may started out wrong, as journalists have no idea how to write foreign names, scientists and experts usually do.

the commenter knows how write foreign names, even if some author succumbed to western stupidity.

It's not my native language either.

Sorry if you felt made fun of.

It's not difficult to detect in Japanese either, because the set of names used for personal and surnames are different. However, both Japanese and non-Japanese alike don't follow any consistent order when writing their names in English, so neither is 'correct'. In fact it could be called a hypercorrection, similarly to using '-san' when addressing Japanese people in English.

It's also easy for chinese names when you know the very limited number of possible surnames. But then you must assume the citator knows some chinese, which they don't.

Japanese is a bit harder as their firstnames are written in myriads of western styles. (e.g. Miu, Miyu, Miyuu, Miju, ... a common female firstname, for "Beauty, Gentleness & Superiority". Mi=Beautiful, Yu=Gentleness, Superiority). Also Miyu can be written in myriads of ways in japanese, with only some being the common female firstname, where yu can also mean Bind, Friend, Eternal, Dream, To exist, Yuzu (a lemon), Sorrow, ...

You need to persist on consistent ordering, even if westerners have no idea and continue ignoring it. Even if everybody writes Itō Mima as Mima Ito, she is still Itō Mima. The prominent Wang Manyu and other chinese table tennis players did establish their correct writing, they just call her Wang Manyu instead of Wang Manyü ("man-yue"), which is equally embarrasing.

You insist on correct gendering, but still write the names wrong.

Japanese people with Western spouses (e.g. Keiko Jackson), or who are popular overseas (Marie Kondo) or have spent a lot of time overseas may prefer to use the Western ordering.

Even people who live in Japan may prefer to use Western ordering when talking in English. Insisting on their own order rather than adapting to others is pretty un-Japanese imo.

Lets not drag Japan into this. They have very high standards in research despite the few examples you gave here, some of which are not even science related.

As a widely accepted measure of this, you can read about the many nobel laureates from japan.

Anyways lets keep politics out of the discussion. It was not my intent anyway, in case you perceived it that way.

> When i said western labs, i spiritually include japan, taiwan, south korean labs in that, since they generally have similar practices and rigor (even if geographically they are in the east) It's difficult to communicate with you if you just redefine common expressions however you see fit. It's like saying "by left, I mean right." Just... stop.

We can debate about expressions/terminology, but these three countries are very very closely aligned with the US. Ofcourse its mutually beneficial.

A joke a military contact cracked once is that the only diff between these three and guam, is that guam is officially recognized as US territory.

Make of that what you will.

Yet somehow those "SC people" issue this opinion without having seen the final paper nor the lab data on the original sample, which is presently being examined as part of the peer review process in SK?

The final paper doesn't mater. If you are in the area, you can skim the paper and look at a few key graphics and tables. Those key graphics and tables should be in the initial draft, because the rest of the article is build around them. Perhaps the final graphs will be prettier, or they will fix some minor errors (like a missing label). (Sometimes it's more complicated. The initial and final version have bigger chang…

In this case, we have only a rough idea how close the leaked papers are to the final paper, with only one statement from a scientist at the national lab in SK stating that there are additional manufacturing steps in the final version of the paper.

I suspect there's a large difference between what was leaked and what will be formally published.

So instead of learning one fact (x country uses family-given ordering) the reader must learn 1000 facts (whether y name is a family name or given name) about a language they don't know so they can infer which ordering the translation is using.
