You have to constantly ask yourself whether this is right and be willing to change your view. And secondly, you can talk to colleagues or conduct interviews to confirm your information. You may use conferences and seminars to try out your ideas. Finally, you can write in a journal, and then receive opinions and criticism from readers. Another difficulty is that viewpoints are sometimes not just viewpoints but positions that aim at achieving certain goals, and are far more difficult to influence than opinions.
People have different goals.
As an analyst, you have to understand different people's positions as well as they do themselves, if not better. You can break down the society, looking for the steps taken in making a decision, the parties involved, etc., but it is equally important to know about the fabric that keeps society together. A human being, basically, is a collection of water and iodine, and as such can be broken down into different components, but when you put them back together, the result is not a living thing, but simply chemicals. Policy analysis requires objectivity during the whole process of analysis, but this does not mean that you cannot have a goal that you continue to pursue. For example, you may be asked to make a series of recommendations on how the Palestinians can best achieve establishing an independent state.
