When considering non-English-language papers:
-25% for male non-native English speakers
-1% for male non-native English speakers from low-income countries
compared to male native English speakers from a high-income country.

Scientific productivity gap for men based on English and non-English papers. Shown are % differences in the number of peer-reviewed papers compared to male native English speakers from a high-income country. The number of years in research is aligned with female counterparts (30 for English non-native and 24 for English non-native & low income).

For those interested to see the productivity gap for men, here are the figures using the same # years in research as female counterparts. Based on English papers:
-50% for English non-native
-58% for English non-native from low-income countries
compared to English native from a high-income country.

Scientific productivity gap for men based on English papers. Shown are % differences in the number of peer-reviewed papers compared to male native English speakers from a high-income country. The number of years in research is aligned with female counterparts (30 for English non-native and 24 for English non-native & low income).

(A) Absolute difference in the number of English-language peer-reviewed papers published between male native English speakers from a high-income country (baseline shown in pink) and male non-native English speakers from a high-income country (solid line in navy), and male non-native English speakers from a lower-middle income country (dashed line in navy). Here, non-native English speakers are defined as those with low English proficiency. (B) Absolute difference in the number of English- and non-English-language peer-reviewed papers published between researchers with the same combinations of the two attributes as (A). (C) Percentage difference in the number of English-language peer-reviewed papers published between researchers with the same combinations of the two attributes as (A). (D) Percentage difference in the number of English- and non-English-language peer-reviewed papers published between researchers with the same combinations of the two attributes as (A).

Thanks and a great point! It's somewhere in the middle but for accurate estimates I need to do some calculations...

Women, non-native English speakers & those form low-income countries are disadvantaged in science but by how much? We found that women with non-English first languages from low-income countries publish up to 70% fewer in English than their counterparts. 1/5

Who gets to do science? A demand for English is hurting marginalised researchers

Everyone, no matter their background, should have an equal chance to work in science – but there are huge systemic barriers.

このような格差の数値化は、あくまで問題解決への第一歩に過ぎません。構造的な障壁を取り除くには、科学のあり方そのものを根本的に見直す必要があるでしょう。例えば、AI利用によって誰もが自分の言語で論文を発表し、読めるような未来を実現することができるかもしれません。このアイデアについては下記論文で検討しています：

一つの対策として、研究者の業績を評価する際に、英語論文のみに基づいた指標の利用をやめることが挙げられるでしょう。DORA（https://sfdora.org/）が提唱しているように、研究がどこで発表されたかではなく、その内容自体に注目した研究者の評価が重要だと考えられます。4/5

実際、英語と非英語の両方の論文を含めると、生産性の格差は大きく減少しました。むしろ、英語を第一言語としない研究者や低所得国出身の研究者は、英語を第一言語とする高所得国の研究者よりも、全体として多くの論文を発表していました。

我々が以前下記の論文でも一例を示したように、女性や英語非ネイティブ、低所得国出身の研究者は科学活動を行う上で様々な障壁に直面しているため、ここで示された生産性の格差は、これらの研究者の真の生産性を反映している訳ではないと考えられます。

Quantifying these disparities is just the first step. Breaking down systemic barriers will likely require a fundamental shift in how we conduct science. One future vision? AI enabling everyone to publish and access research in our own languages. We explore this idea here:

We should stop using metrics based solely on publications in English to evaluate the performance of researchers. Instead we should focus on *what* is published, not just *where*, as advocated by DORA: sfdora.org

Indeed when we included both English and non-English publications, the productivity gap narrowed significantly. Non-native English speakers and researchers from lower-income countries often publish *more* papers overall than their native English-speaking, high-income counterparts.
3/5

Scientific productivity gap narrows significantly, when we look at total publications including those in non-English languages. Shown are the maximum % differences in the number of English-language and non-English-language peer-reviewed papers published by female native English speakers from a high-income country (-45%), female non-native English speakers from a high-income country (-35%), and female non-native English speakers from a lower-middle income country (-25%), compared to male native English speakers from a high-income country (red flag).

Obviously this does not reflect the true productivity of researchers facing gender, economic and #languagebarriers, as they face tremendous hurdles when conducting various scientific activities, as we previously showed in this paper for non-native English speakers:
doi.org/10.1371/jour...
2/5

Estimated disadvantages for non-native English speakers when conducting different scientific activities. The height of hurdles indicates the relative length of time taken to read an English-language paper (Reading), to write a paper in English (Writing), and to prepare an oral presentation in English (Presentation), and the relative frequency of an English-language paper being rejected (Paper rejection) or requested to revise (Paper revision) due to English writing, for non-native English speakers (Non-native), compared to native English speakers (Native).

Much pest and disease data is in grey literature or on ephemeral web sites. Collected by government departments and agencies but they don’t publish. In the global south trade magazines and newspapers may contain earlier reports than official sources. There is a place for AI web crawlers.
