Hmmm. Ok, this chap sounds like he may indeed have a hair trigger personality (Said German man), but we have to take on board that we don’t know what happened/how many times he has to respond on this a day/his perception of the interaction…
I live in London UK and we have every accent known to man in many places: work/social etc. so I think I have a good level of experience to postulate a theory.
One could postulate that Germanic/Slavic accents when used to pronounce English DO seem to elicit a negative response from other folk watching how interactions pan out.
I have a soft Irish accent and have worked variously with German/Afrikaans/Dutch accented colleagues. More recently with migration patterns, Eastern European folk.
I have noted that, when people don’t actually know the nationality of a given colleague and don’t have a finely enough tuned ear to distinguish between the various accents that my (very polite) colleagues with accents that are more ‘clipped’ get complaints for being rude. I can often say exceptionally harsh things (not out of malice but because they need to be said) and people think Im utterly charming. My colleagues may say something comparatively less controversial and get complaints for being abrupt and rude.
Essentially the prosodic features of speech appear to be read on a profoundly subtle level which overrides the actual subject matter or words. Throw in the right accent with an ‘acceptable’ cadence and you can get away with a lot more than a more monotone or regulated cadence.
Somewhere underneath the process you have to wonder if history and media presentation leaves a taint of ‘Germanic = nasty’ ‘Irish = trustworthy’, ie a subtle but powerful nationality bias…
If I approach a person expecting a negative interaction, I know it alters my approach and will show in my body language, general openness and the features and content of my speech. I’ve pre-programmed the interaction to be less positive without meaning to. So, similarly, if anyone approaches an interaction and hears an accent that they make a subtle judgement upon then the same phenomenon is possibly going to occur…
We take cues from all sorts of information and speech patterns are a basic cue. If you then draw further upon a culturally biased expectation that you’re going to have a less positive interaction then you’ll feed that dynamic and find negativity or create it where it was not there to begin with.
I’m not saying that was the actual case in the experience of the contributor who commenced the thread but it’s worth a thought…
