Answer:
Mechanical solidarity
Step-by-step explanation:
Mechanical solidarity refers to a sense of closeness / comradely that is formed between individuals who believe that they have a same belief, value, or goals.
When we are in the group with this high degree of 'sameness' we tend to form a collective conscience which make us become more likely to cooperate with them because we see parts of ourselves within them. In general, this type of solidarity tend to be stronger compared to the ones in a group that is formed without any basic similarities.
