When we collaborate with others to tackle novel problems, we anticipate how they will perform their part of the task to coordinate behavior effectively. We might estimate how well someone else will perform by extrapolating from estimates of how well we ourselves would perform. This account predicts that our metacognitive model should make accurate predictions when projected onto people as good as, or worse than, us but not on those whose abilities exceed our own.We demonstrate just such a pattern and that it leads to worse coordination when working with people more skilled than ourselves. Metacognitive projection is associated with a specific activity pattern in anterior lateral prefrontal cortex (alPFC47). Manipulation of alPFC47 activity altered metacognitive projection and impaired interpersonal social coordination. By contrast, monitoring of other individuals’ observable performance and outcomes is associated with a distinct pattern of activity in the posterior temporal parietal junction (TPJp).

The epistemological chasm between how we (implicitly and subjectively) perceive or imagine the actual world and how we (explicitly and “objectively”) think of its underlying entities has motivated perhaps the most disconcerting impasse in human thought: the explanatory gap between the phenomenal and physical properties of the world. Here, I advocate a combination of philosophical skepticism and simplicity as an informed approach to arbitrate among theories of consciousness. I argue that the explanatory gap is rightly a gap in our understanding, but one that is not surprising; and we being observers biased by our first-person perspective and our existence may both hinder and (the realization we have them) assist our reasoning. Further, I unfold the concept of observer into two distinct notions based on its functional and phenomenal aspects, and exploit this device to elucidate the subject-observer relationship. Then, I proceed to analyze the philosophical zombie dilemma. Lastly, I contend that from a skeptical viewpoint, panpsychism (or neutral monism) is the most parsimonious doctrine accounting for the explanatory gap, and suggest that it would be possible to make headway in the hard problem of consciousness by uncovering non-trivial causal relationships between qualia states and functional states, if routine and controlled manipulation of neural circuits were easily available.
