Consciousness Theories Throw Down in a Research Royale!

This review compares and contrasts three theories of consciousness—Integrated Information Theory, Neurorepresentationalism, and Active Inference—that are being directly tested against each other in a "research competition." The review focuses on what each theory attempts to explain, how they explain it, and the methods used to test them, highlighting key hypotheses under investigation.

Possible Conflicts of Interest

The research was funded by the Templeton World Charity Foundation. While the authors state their opinions do not necessarily reflect the views of the foundation, this funding source could introduce a potential bias, particularly given the philosophical implications of consciousness research.

Identified Weaknesses

Theoretical/Review Paper

This paper primarily reviews existing theories and proposes experimental designs, so it doesn't present any novel empirical data. The value of this adversarial approach lies in the future experimental results, not this review itself.

Complexity of Theories

The theories discussed are highly complex and nuanced, making it challenging to design experiments that definitively support one over the others. Interpreting the experimental outcomes may also be contentious.

Reliance on Auxiliary Hypotheses

Testing the core claims of each theory requires reliance on auxiliary hypotheses (e.g., about how to measure or manipulate neural activity). If experimental predictions are not supported, it may be difficult to determine whether the core theory or the auxiliary hypotheses are at fault.

Rating Explanation

This review lays the groundwork for an ambitious and potentially impactful research project. The adversarial collaboration approach, while not without its challenges, holds promise for advancing our understanding of consciousness by promoting rigorous testing of competing theories. The lack of novel empirical data in this review prevents a higher rating.
