One's culture determines how close we stand when talking with another, or how much eye contact we demand. Culture also determines what non-verbal signs we use to express anger or hatred or trust or approval. Don't underestimate the cultural differences in the interpretation of non-verbal forms of communication. What is a gesture of joy in one culture may be considered a rude insult in another.Consider the case of one British businessman in Iran. After months of doing the right thing — building relationships with Iranian colleagues, respecting the influence of Islam on negotiations and avoiding any potentially explosive political small talk — the executive was elated once a formal contract was signed. He signed the papers and turned to give his Persian colleagues a big thumbs-up. Almost immediately there was a gasp and one Iranian executive left the room. The British executive didn't have a clue as to what was going on — and his Iranian hosts were too embarrassed to tell him.The explanation was really quite simple. While the thumbs-up gesture means "good, great, well-played" in Britain, in the Persian culture it is a sign of discontent and borders on the obscene. "I don't think I was ever more embarrassed in my life. I felt like a child who yells out a vulgar curse word without having any clue as to what it means," the executive says, "My colleagues accepted my plea of ignorance but the relationship was damaged. It wasn't that they thought I had truly meant the gesture as interpreted in their culture but rather that I was totally ignorant of it. I just never suspected there was anything wrong with it."The lesson here is simple. Communicating effectively across cultures requires more than understanding the written and spoken language. It involves a basic knowledge of the acceptable non-verbal forms of communication within a culture as well. In this case experience is probably the best teacher.
