Why would political scientist wish to consult multiple sources of information on a topic?

Just about 5 years ago, political scientists were not known to most of the population, especially in Spain. With the political changes that have taken place in our country, political professionals called political scientists have appeared on television, press and radio.

In the beginning, it should be clarified that being a political scientist is not being a politician. You can be a politician without having studied the career of Political Science and vice versa. The political scientist is trained in different social and humanistic branches related to the management of matters of public interest and are connected with the knowledge of States and Public Administration.
The political scientist uses political science, a discipline that defends the gray and not extreme in any way.
The professional political scientist investigates the social and political reality that surrounds him to remove the bases and then evaluate the possible development of different public policies or aspects that affect different groups.
