Fig 9. Model comparisons predicting COVID-19 attitudes for the first-wave survey using leave-one-out (loo) cross-validation information criteria.

Error bars indicate SE of estimate. The simplest model within the SE of the full model, “Big 5 –politics”, includes the five strongest predictors of responses on the COVID-19 severity scale (i.e., the five predictors shown in Fig 8), and does not include participants’ political attitudes.
