Being highly social animals, human communicate with one another to convey emotions and danger, to build relationships and to maintain social order. Since infancy, we have been developing communicative skills by crying and smiling at the right moment to achieve what we want. Not much have changed even as we reached adulthood. However, ideas and needs have become more complex and thus more effective communication is needed to convey such messages.
Effective communication is needed to prevent misunderstandings. A criticism from a superior to a subordinate can have drastically different effect depending on the choice of words used. Consider “You did a horrible job” as compared to “this piece of work can be improved”, which criticism would the subordinate more willing to accept? Often, we make the mistake of assuming that others understand exactly what we are trying to convey. However, this is often not so. How often has a woman drop hints about a birthday wish only to be met with disappointment?
Effective communication is also needed to express ideas and thoughts. A scientific hypothesis or design require funding and support of others in the field, and even members of the public to make it into a reality. However brilliant your ideas, they are worthless unless you can make people agree with you.
Moreover, effective communication can boost self-esteem. One who is able to communicate his thoughts effectively tends to be more confident when meeting people and sharing ideas.
There is hardly any aspect of life that does not require communicative skills. Communicative skills are required to maintain and form human relationships, including: parent and child, husband and wife, superior and subordinate, between friends, colleagues, and even countries. By maintaining good relationships, we can avoid hostility, receive aids, support and even promotions more easily. Maintaining good human relationships are practically essential for the survival of a human being. (Edited)
