How do political ideology and perceived ideological alignment influence supply chain professionals' evaluation of operational decisions involving politically charged macroeconomic issues such as tariffs?

In an increasingly volatile global trade environment, supply chain leaders are routinely required to make decisions influenced by macroeconomic forces like tariffs, trade restrictions and geopolitical tensions. A new study in Transportation Journal examines a critical but underexplored dimension of these decisions: how political ideology shapes professional judgment—even when individuals are presented with identical operational information.

Scott DuHadway of Portland State University and Craig Carter of Arizona State University conducted a controlled experiment with 216 supply chain professionals to assess how political context influences the evaluation of a sourcing plan tied to tariff conditions.

The findings suggest that supply chain decision-making is not purely technical. Instead, it is shaped by underlying ideological cues that can alter perceptions of both the decision and the decisionmaker.

"When evaluating identical sourcing strategies tied to tariffs, we found that participants' political ideology and their perceptions of a manager's ideology significantly shaped both trust in leadership and support for the operational plan," DuHadway said. "Even neutral presentations of politically charged issues were enough to activate bias and influence decision-making."

Even when managers attempt to present information neutrally, politically charged topics like tariffs can unintentionally activate bias, influencing how their recommendations are received.

This research is particularly timely as organizations increasingly navigate politically sensitive supply chain environments, where trade policy and economic nationalism are shaping sourcing decisions.
