Taylor: Researchers at a local university claim that 61 percent of the information transferred during a conversation is communicated through nonverbal signals  But this claim, like all such mathematically precise claims, is suspect, because claims of such exactitude could never be established by science  Sandra: While precision is unobtainable in many areas of life, it is commonplace in others
Many scientific disciplines obtain extremely precise results, which should not be doubted merely because of their precision
The study of verbal and nonverbal communication is an area where one cannot expect great precision in one's research results.
