His principal research interests are in International Relations theory and meta-theory, especially causation and causal explanation, realism and neo-realism, the English School, and the relationship between theory and history. He also has research interests in British foreign and defence policy, strategy, and the ethics of war.Hidemi Suganami studied International Relations at Tokyo, Aberystwyth, and London Universities.

• Part I - Metaphysics 1: Hume and the Regularity View of Causation 2: Bhaskar, Causal Realism, and the Conduct of Causal Inquiry 3: Beyond Causal Realism and Idealism: Van Fraassen and the Possibility of Agnosticism Part II - Methodology 4: Causal Statements 5: The Logic of Causal Inquiry 6: Causal Explanation 7: Causal Reasoning 8: Examples

In Causal Inquiry in International Relations (2024), Adam Humphreys and Hidemi Suganami have made an outstanding contribution to ongoing debates about causality in our field and in the social sciences in general. The methodological aspects of causal inquiry deserve the kind of attention that the authors give them, and the conversation that Humphreys and Suganami are advancing is critical to the evolution of the field. They should be commended for a splendid statement and acknowledged for the richness of the discussion about their analysis that will hopefully ensue.
