From one of the sources of the article: [1]
>> In Study 1, White and Asian nonnative speakers using the same scripted responses as native speakers were found to be significantly less likely to be recommended for a middle-management position, and this bias was fully mediated by assessments of their political skill.
>> Nonnative speakers were found to have a significantly lower likelihood of receiving new-venture funding
That's an interesting bias, I wonder if/how it varies by accents, as those can be quite different. Are foreign accents from countries where English is still a major language like U.K., Australia, India, ..., perceived differently than foreign accents from non english-speaking countries?
