Regression Results for Experiment 2.

<p><i>Note.</i> The 3-way interaction between charity framing, social political ideology, and perceived politics of the charity was tested initially but was not significant and was subsequently dropped from the model. Social political ideology and perceived politics were measured on a scale of −3 (<i>strongly conservative</i>) to 3 (<i>strongly liberal</i>) and charity framing was dummy coded as community (<i>0</i>) or religious (<i>1</i>). All statistics reported are unstandardized regression coefficients and should be interpreted in the context of these scales. Significance tests for <i>t</i> statistics associated with unstandardized regression coefficients are reported as <i>p</i> values:</p>*<p><.01,</p>**<p><.001,</p>***<p><.0001.</p

Regression Results for Experiment 1.

<p><i>Note.</i> The 3-way interaction was tested and dropped from the model, so the model reported in the text has only main effects and 2-way interactions. Political ideology was measured on a scale of −3 (<i>strongly conservative</i>) to 3 (<i>strongly liberal</i>). Charity framing was dummy coded as community (<i>0</i>) or religious (<i>1</i>) and religious group membership was dummy coded as nonreligious (<i>0</i>) or Christian (<i>1</i>). Unstandardized regression coefficients should be interpreted in the context of these scales.</p
