Although you did not attach the section or any further reference, we can say the following.
United States President George Washington liked to include multiple opinions in his decision making. This showed that he had a fair, open-minded leadership style because he liked to include many men from different backgrounds and political points of view in his cabinet.
For example, that was the case of federalists Alexander Hamilton, John Jay, or James Madison. On the other hand, Washington also included Antifederalists in his cabinet as was the case of Thomas Jefferson
This showed that Washington liked to hear different voices and was confident enough to make the right decision in the end.
