Table 3.

The parameter settings associated with each condition of Experiment 2

Experiment	Reps	$N$	$J$	$\theta$
Condition 1	2	20	4	0.6
Condition 2	1	20	1	0.6
Condition 3	1	20	4	0.8
Condition 4	2	5	4	0.6
Condition 5	2	5	1	0.6

Note. The repetitions (reps) is the number of repetitions of the parameter settings we ran. $N$ is the number of participants per generation. $J$ is the number of flights, that is the amount of evidence, shown per spaceship design trial. $\theta$ gives the probability of success of good parts, and the probability of failure of bad parts—that is, the strength of evidence.
