Convergent vs. Discriminant Validity: Which Is More Important?

I partly agree that discriminant validity is important for distinguishing constructs and avoiding misleading relationships. However, I believe convergent validity comes first. As noted by Fornell and Larcker (1981), a construct must be measured well before comparing it with others. In my data, some constructs loaded together in EFA, suggesting issues with both convergent and discriminant validity. So, convergent validity is the foundation, while discriminant validity ensures clarity between constructs.
