Appendix 3—table 21. Test performance as a function of exploration-phase EIG coefficient.

	Pre-registered sample		Preliminary sample
	(194 participants)		(62 participants)
Term	Median	95% PI	Median	95% PI	Units
Predictors
Intercept	1.57	[1.52, 1.62]	1.61	[1.52, 1.71]	logit
Coefficient for EIG	1.98	[1.77, 2.22]	1.72	[1.37, 2.11]	logit² / nat

The model can be summarized with the following R syntax formula: $testaccuracy\sim 1+EIG$, where EIG is the mean posterior parameter for each participant in the model described in Appendix 3—table 4. The model described here was fit as a logistic regression with binomial likelihood.
