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

I believe the answer is: to corroborate a given primary sources claim about an event

By consulting to multiple sources, a political scientists could examine a certain political event form various perspective. By doing this, they could see whether the claim that a certain political party or candidate throw is true or not and help to provide the credibility of this claim to the public.

explanation:

actually, not all representation was acceptable based on this little piece of article, in 1776, the second continental congress issued the declaration of independence, stating their specific grievances with the british monarchy and why they were going to create a separate government. after the colonies separated from the british monarchy and formed the united states of america, they had to answer some crucial questions: 1) if not a monarchy, what type of government was the united states going to have? 2) what kind of government was going to protect the people without violating their individual liberties?

this question your asking is true hope this and you get a 100 percent : )
