An individual who confuses private ethics with business morality does not make an effective negotiator.

Private ethics are personal beliefs and values that guide an individual's behavior in their personal life, while business morality refers to the principles and standards that guide actions and decisions in the business world. Confusing the two can lead to ineffective negotiation as it could result in a lack of objectivity and a failure to understand the business context and priorities. Effective negotiators must have a clear understanding of business morality and be able to separate it from personal ethics.
