Answer:
The principle of homophily
Step-by-step explanation:
This is the principle in which individual is attracted to individuals of shared beliefs, characteristics and bonds. These shared traits are the attraction points. In my opinion, they operate on the principle of "birds of a feather flocks together or be on the same wavelength." It is these traits that makes them attracted to each other, and also it makes communication easier for them due to the shared beliefs, bond, characteristics, etc.
