Fig. 3: Paranoia, state proactivity, task behaviour and belief updating during a pandemic.
From: Paranoia and belief updating during the COVID-19 crisis
Paranoia increased as the pandemic progressed (F(2, 530) = 14.7, P < 0.001, ηP2 = 0.053). a, Self-rated paranoia (n = 533) before the pandemic, during lockdown and after reopening. b, We observed a main effect of the pandemic period (F(2, 527) = 4.948, P = 0.007, ηP2 = 0.018) and a state proactivity by period interaction (F(2, 527) = 4.785, P = 0.009, ηP2 = 0.018) for paranoia and win-switch behaviour (main effect: F(2, 527) = 3.270, P = 0.039, ηP2 = 0.012; interaction: F(2, 527) = 8.747, P < 0.001, ηP2 = 0.032) and volatility priors (F(2, 527) = 8.623, P = 0.001, ηP2 = 0.032). We observed significant interactions between pandemic period and the proactivity of policies. The centre horizontal lines within the plots represent the median values, the boxes span from the 25th to the 75th percentile and the whiskers extend to 1.5× the interquartile range.
