When managers are asked this question How ethical are you? They usually reply that they are ethical but you are probably not. We sometimesmake unethical decisions unconsciously. This article explains four related sources of unintentional unethical decision making. They are implicit forms of prejudice, bias that favors one's own group, conflict of interest and overclaiming credit. Implicit forms of prejudice is also known as unconscious stereotypes and attitudes towards people. In the mid 1990's professor Tony Greenwald (university of Washington) developed a tool called Implicit Association Test (IAT). This test exposes your decisions making based on race, gender, religion and so on. Bias that favors your group. We have probably all done this. Referred a friend, or relative to get a job. We tend to do favors for those that are similiar to us. Perhaps same race, religion, employer or attend the same school. This is called in group favoritism. While discriminating these who are different from us is consider un-ethical. We tend to judge African Americans, Arabs, poor, gays and lesbians. On the contrary, 75% of testakers (IAT) will choose the young, rich and white. Conflict of interest can lead to intentionally corrupt behavior. Experiments show how powerful such conflicts can unintentionally change decision making. Several examples are a physician accepting payments from clinical trials, lawyers fees based on their clients settlements. Overclaiming credit is when you give yourself too much credit, for example rating yourself above average from intelligence to driving ability. Unconscious overclaiming credit can reduce the performance and logevity of an organization. If an employee learns that someone else is getting payed more it will affect its perfomance and probably resign. Managers can make more ethical decision if they become mindful of their unconscious biases. We can make these adjustments by following these three general categories: collecting data, shaping the environment and broadening the decision making process. Collecting more data to reveal its presence may often be counterintuitive. To many people surprise, after taking the IAT, they would learn of their own races and racial biases. Research shows that shaping your environment implicates attitudes by external cues in environment. Broaden your decision making is an example of an experiment of philosopher John Rawls's concept of the "veil of ignorance" which means that only a person ignorant of his own identity is capable of a truly ethical decision. Companies are focusing on changing these uncoscious attitudes by creating ethics training programs for managers, as well as taking courses for professorships in ethics. To answer the question at the beginning of these article, it is clear that some might have a different opinion. It is very interesting how unaware people could be when it comes to ethics. I had a very different definition in mind of what ethics meant. This article made me realize that I have been very unethical at my work place without even noticing. I got to really understand what ethics really means and what is it about.
