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 doi.org/10.1371/jour... #languagebarriers
Scientific productivity gap based on English-language peer-reviewed papers. Shown are the maximum % differences in the number of 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 (-60%), and female non-native English speakers from a lower-middle income country (-70%), compared to male native English speakers from a high-income country (red flag).
