Politics in the logistics mix: How tariffs and polarization alter corporate supply chains

KUALA LUMPUR, 24 JULY 2026 —

A recent study has found that political ideology and perceived ideological alignment play a significant role in supply chain professionals' evaluation of operational decisions involving macroeconomic issues such as tariffs. The research, published in the Transportation Journal, suggests that even when presented with identical operational information, supply chain leaders' decisions are influenced by underlying ideological cues.

This finding has significant implications for organizations navigating complex global trade environments, where trade policy and economic nationalism are increasingly shaping sourcing decisions.

The study, conducted by Scott DuHadway of Portland State University and Craig Carter of Arizona State University, involved a controlled experiment with 216 supply chain professionals. The researchers assessed how political context influences the evaluation of a sourcing plan tied to tariff conditions, and found that participants' political ideology and their perceptions of a manager's ideology shaped both trust in leadership and support for the operational plan.

The findings indicate that supply chain decision-making is not purely technical, but is instead influenced by bias and ideological considerations. According to DuHadway, "Even neutral presentations of politically charged issues were enough to activate bias and influence decision-making."

The research has significant implications for organizations operating in today's volatile global trade environment. With the increasing use of tariffs and trade restrictions, supply chain leaders are routinely required to make decisions that involve complex macroeconomic issues. The study suggests that these decisions are not made in a vacuum, but are instead influenced by the political ideology and perceived ideological alignment of the decision-makers.

This highlights the need for organizations to be aware of the potential for bias in supply chain decision-making, and to take steps to mitigate its impact. Details on how organizations can address this issue are not yet available.

In the Malaysian market, the impact of tariffs and trade restrictions on supply chain decisions is likely to be significant. As a major trading nation, Malaysia is heavily reliant on international trade, and changes in global trade policies can have a major impact on the country's economy.

Malaysian companies operating in industries such as manufacturing, logistics, and distribution are likely to be particularly affected by changes in tariff policies, and will need to be aware of the potential for bias in supply chain decision-making. The study's findings suggest that Malaysian companies should take a nuanced approach to supply chain decision-making, taking into account both technical and ideological considerations.

The study's findings also have implications for specific sectors and companies in Malaysia. For example, companies operating in the electronics and automotive sectors, which are heavily reliant on international trade, may need to be particularly aware of the potential for bias in supply chain decision-making.

Additionally, companies with global supply chains, such as those in the logistics and distribution industries, may need to take steps to mitigate the impact of bias on their supply chain decisions. Details on how specific companies in Malaysia are responding to these challenges are not yet available.

Looking ahead, the study's findings suggest that supply chain professionals and organizations will need to be increasingly aware of the potential for bias in decision-making, particularly in relation to politically charged macroeconomic issues such as tariffs. As the global trade environment continues to evolve, companies will need to take a nuanced approach to supply chain decision-making, taking into account both technical and ideological considerations.

With the increasing use of tariffs and trade restrictions, the need for awareness of bias in supply chain decision-making is likely to become even more pressing in the future. The study's findings provide a timely reminder of the importance of considering the potential for bias in supply chain decision-making, and highlight the need for further research in this area.
