In the past I managed quants, IT people, etc and a depressing % of the arguments I had to referee were over miscommunication of ideas, over definitions, and on a number of occasions where the factions actually agreed but didn't realise it.
Anyone who has managed in this environment will recognise this, and therefore will value the ability to articulate their position.
I would also add that I have found that I dumb down my English significantly when talking/writing to quants, initially that was unconscious, but now I catch myself when using non trivial words. I suppose I should respect other cultures, but in the 21st century I don't accept any excuse for not speaking English, regardless of your origin. I deal with people not only from every country on Earth, but a few places that aren't even recognised as states. If someone from a village in China so out of it that they only have one telephone can use the word "obsequious" in the right context, but also explain the problems of orbits in monte carlo, then pretty much no one has an excuse.
I'm going off-topic but I can't resist the temptation. You should include the USA as "other culture." Speaking, listening, reasoning, and writing skills are abysmal here. I can't think offhand of a single American I'd like to spend half a day at an airport with: the mere prospect fills me with dismay. The lack of such skills is endemic to the USA, from the braying of senior politicians on the television screen to the ordinary yob in the street. I don't quite know what the root cause of this malady is. I'm confining myself to words alone: in England a subtle hand gesture, a raised eyebrow, a pursing of the lips, a pregnant pause, can convey volumes, but let's not get into this here as it requires a homogeneous national culture conspicuous by its absence on these shores.
