Using '결속력' when simply referring to efficient cooperation. → If the focus is just on working together efficiently without necessarily implying a deep emotional bond or shared identity, simpler terms like '협력' (cooperation) or '팀워크' (teamwork) might be more appropriate.

Confusing '결속력' with '단결'. → '단결' is the act or state of uniting, while '결속력' is the underlying force that enables and sustains that unity.
