I need help determining if I have identified the correct bias for "The Building Blocks of a Supply Chain Management Theory: Using Factor Market Rivalry for Supply Chain Theorizing" by Ralston et al. (2021).

The study conducted by Ralston et al. (2021) appears to exhibit characteristics of confirmation bias. The researchers' inclination towards proving factor market rivalry as a theory for supply chain management may be seen as a potential source of bias in their work.
