Studies of cohabiting couples are prone to self-selection bias.

Question

Quizplus · Accepted Answer

Cohabiting couples are not a random sample, as individuals who choose to cohabit may have different characteristics than individuals who do not, leading to self-selection bias. For example, individuals who are less traditional or less committed to marriage may be more likely to cohabit than those who value marriage more highly. Therefore, studies of cohabiting couples need to be interpreted with caution, as they may not be representative of all couples or individuals.
