There are many skill sets that humans develop as they work through life. Some are based on the innate set of programmed instincts that inhabit all of us. Other skills are learned as we go, providing a summation of the varied experiences we rack up over time. There is a mixture of influences that stands behind the people we become. Some factors are inherent to the game and cannot be denied. Other characteristics of our personalities are forged by the interactions and experience we log. There are distinct differences between the nature and nurture outcomes, but it could be argued that most of our traits are the result of a myriad of influences.
Negotiation skills begin to emerge in the early stages of our lives. Infants have the same general human needs that adults do, except that children are wholly incapable of securing any of the things they need on their own. As a result, an instinctual bargaining method must be employed by children. It could be argued that there is operant conditioning behind the phenomenon, but there is a strong likelihood that at least some of the behavior is innate. Adults often enroll in negotiating courses to enhance their bargaining skill set. The ability to influence outcomes in a favorable way is very valuable in a business environment.
