Prediction Errors and Comparisons of the Seven Models in Studies 1 Through 4

Model	Mean square error				Model comparison from the meta-analysis
	Study 1	Study 2	Study 3	Study 4
1. Ideology only: ŷ = 0.022 − 1.420(ideology)	0.015 (0.019)	0.021 (0.030)	0.035 (0.086)	0.022 (0.035)	More accurate than Models 3, 4, 5, 6, and 7
2. Ideology, status, and choice: ŷ = 0.016 – 1.505(ideology) + 0.128(status) + 0.072(choice)	0.013 (0.020)	0.021 (0.032)	0.037 (0.096)	0.023 (0.038)	More accurate than Models 3, 4, 5, 6, and 7
3. Conventionalism only: ŷ = 0.157 − 1.947(conventionalism)	0.040 (0.076)	0.054 (0.083)	0.039 (0.047)	0.055 (0.065)	More accurate than Models 5, 6, and 7
4. Conventionalism, status, and choice: ŷ = 0.166 − 1.827(conventionalism) – 0.076(status) − 0.185(choice)	0.041 (0.078)	0.047 (0.079)	0.033 (0.045)	0.049 (0.070)	More accurate than Models 5, 6, and 7
5. Status only: ŷ = 0.001 – 0.846(status)	0.090 (0.153)	0.081 (0.138)	0.095 (0.091)	0.072 (0.106)	Not more accurate than any models
6. Choice only: ŷ = 0.041 – 0.398(choice)	0.108 (0.166)	0.093 (0.122)	0.111 (0.114)	0.074 (0.117)	Not more accurate than any models
7. Null: ŷ = 0	0.111 (0.155)	0.095 (0.135)	0.113 (0.101)	0.076 (0.117)	Not more accurate than any models

Note: For each model, the table presents mean square errors in the four studies, with standard deviations in parentheses.
