Mean scores for the 'Novelty' and 'Attitudes toward Regulation' indices for NSE, NEHS, and NREG groups.

The continuum from ‘high’ to ‘low’ represents a factor score range of +/− 0.5, representing one half standard deviation in either direction from the index. a, b, and c markings indicate significant differences between groups, where a: NSE and NEHS, b: NSE and NREG, c: NEHS and NREG. Tukey HSD post hoc analysis confirms that differences in index scores are significant across all three groups for ‘Novelty’ (p<.05; NSE: N = 180, M = −0.29, SD = 0.86, NREG: N = 103, M = 0.39, SD = 0.88, NEHS: N = 121, M = 0.11, SD = 0.85), and for ‘Regulation: Preference for Precaution’ (p<.001; NSE: N = 180, M = −0.29, SD = 0.82; NEHS: N = 121, M = 0.06, SD = 0.93; NREG: N = 103, M = 0.43, SD = 0.81). Post hoc analysis confirmed a significant difference between NSE and NREG groups only for ‘Regulation: Market-Based, Voluntary’ (p<.022; NSE: N = 180, M = −0.08, SD = 0.80; NREG: N = 103, M = −0.21, SD = 0.91).
