TABLE 6.

Proportion of participants who judged protective behaviours as under their control and correlation with conspiracy beliefs

			Correlation with conspiracy beliefs (Spearman ρ)
	Uptake M (SD)	control (% yes)	Control (0/1)	Utility	Behaviour uptake/intention
High in control
Hand‐washing (1‐4; n = 396)	3.63 (0.74)	99%	.06	−.16**	.02
Staying home (1‐4; n = 382)	3.73 (0.55)	96%	.07	−.01	.03
Face masks (1‐4; n = 334)	1.47 (0.95)	92%	.10*	−.03	.14**
Gloves (1‐4; n = 336)	1.55 (0.95)	93%	.13*	−.10*	.11*
Washing groceries (1‐4; n = 349)	1.69 (1.69)	94%	.13*	−.01	.05
Stockpiling (1‐4; n = 399)	2.74 (0.99)	87%	.08	−.01	−.04
Mixed perception of control
Social distance (1‐4; n = 368)	3.63 (0.58)	63%	−.00	−.14**	−.07
Contact tracing app (1‐5; n = 399)	3.55 (1.30)	.60%	.08	−.10*	−.13**
Low in control
Diagnostic test (1‐5; n = 399)	4.28 (0.92)	.25%	−.02	−.18***	−.20***
Antibodies test (1‐5; n = 399)	4.16 (1.07)	.24%	−.05	−.19***	−.26***
Vaccination (1‐5; n = 399)	3.55 (1.30)	.24%	−.05	−.29***	−.33***

Note: * p < .05, ** p < .01, *** p < .001. The proportion of judgments that the behaviours were under one's control were all significantly greater than 50% for the high and mixed control behaviours (binomial test p < .005), and lower than 50% for the low control behaviours.
