Why do some groups have very low levels of cohesivenes?

Some groups exhibit low levels of cohesiveness due to factors such as poor communication, lack of shared goals, and differing values or interests among members. Additionally, interpersonal conflicts and competition can undermine trust and collaboration. External pressures or a lack of resources may also contribute to a fragmented group dynamic. Ultimately, these elements hinder the development of strong relationships and a unified purpose within the group.
