	M (SD)	Pearson’s correlations
Variable		2	3	4	5	6	7	8	9	10
Personal attitude
1. Agreement target statement	3.96 (2.04)	−.323**	−.019	−.142**	.084**	.027	.039	−.253**	.046	−.083**
2. Agreement alternative statement	3.77 (1.90)		−.054	−.149**	.100**	−.065*	.151**	.301**	.166**	−.133**
3. Polarization Index	0.34 (0.22)			.189**	.058*	−.002	−.092**	−.109**	−.053	.075**
4. Opinion differentiation	4.29 (1.33)				.097**	−.138**	−.166**	−.119**	−.213**	.228**
5. Structural differentiation	4.38 (1.24)					−.148**	.149**	.103**	.257**	−.243**
6. Conversational harmony	3.73 (1.27)						−.264**	−.140**	−.132**	.102**
7. Avoidance	3.65 (1.25)							.222**	.260**	−.287**
8. Negative emotions	3.01 (1.58)								.432**	−.149**
9. Relationship threat	2.93 (1.51)									−.266**
10. Incrementality	3.87 (1.29)

Note. Polarization Index scores range from 0 (no polarization) to 1 (maximum polarization). All other variables are measured on 7-point scales, with higher scores indicating higher agreement with the target statement (1), higher agreement with the alternative statement (2), larger perceived opinion differences (4), higher perceived structural differentiation (5), higher anticipated conversational harmony (6), higher intentions to avoid (7), more anticipated negative emotions in response to the target statement (8), higher experienced relationship threat (9), and stronger beliefs that people can change their opinions about the issue (10).

Asterisks indicate that unilevel correlations are significant at *p < .05. **p < .01. ***p < .001.
