Paranoia, self-deception and overconfidence
Fig 5
A, Difference between the relative perceived choice reliability (rank of ωns) and relative objective classification performance (rank of C1 accuracy) is correlated with confidence-weighted self-deception. A higher ωns represents a lower perceived choice reliability (analogously, a higher perceived choice unreliability), so individuals scoring high on this rank difference have high perceived unreliability and low ability. This relationship is significantly stronger in the high paranoia group compared to the low paranoia group. B, High paranoia is responsible for elevated ωns independent of anxiety. The high paranoia high anxiety group showed similar values of ωns to the high paranoia low anxiety group, while the low paranoia high anxiety group had a significantly decreased ωns.
