We first tested H1a and H2a, to examine whether perceived minority threat would be lower or higher directly after the coup versus before the coup, as well as whether perceived threat would change a year after the coup relative to right after the coup. We statistically compared perceived ethnic minority threat and perceived Muslim threat before (when the threat of coup was low), right after the coup (when the threat of coup was high) and a year after the coup (when we assumed citizens would habituate) in two separate models. Each model consisted of an ANCOVA in which perceived minority threat was predicted by wave and the demographic variables. Gender (0 = “man”, 1 = “woman”), city-resident (0 = “Living in a town or a village”, 1 = “living in a city”) and religion (0 = non-Buddhist, 1 = Buddhist) were dummy-coded before being entered to the regression. The assumptions of the models reported in this study were assessed and deemed satisfied after visual inpection of the assumption plots.
In the first model, perceived ethnic minority threat differed significantly between time points (F(2, 5045) = 87.28, p < .001, \({\eta }_{p}^{2}\)= .03). Tukey contrasts showed that both in wave 2 (w2-w1 = − .72, p < .001) and wave 3 (w3-w1 = − .44, p < .001) perceived minority threat (i.e., after the coup) was lower than in wave 1 (i.e., before the coup). Due to lack of measures of perceived societal threat in wave 1, we cannot test differences between wave 1 and the other waves in perceived societal threat. However, we did find statistical support that perceived societal threat decreased from wave 2 to wave 3 (w3- w2 = − .36, F(1, 4065) = 59.76, p < .001, \({\eta }_{p}^{2}\)= .01), which coincided with an increase in perceived minority threat from wave 2 to wave 3 (w3-w2 = .28, p < .001). The model yielded support for H1b, that the onset of the military coup (being associated with perceived threat) coincided with lower perceived minority threat and that a decrease in perceived threat in the aftermath of the coup coincided with an increase in perceived minority threat (see Fig. 2).
In the second model, perceived Muslim threat differed significantly between time points (F(2, 4892) = 25.51, p < .001, \({\eta }_{p}^{2}\) = .01). Tukey contrasts showed that in wave 2 (w2-w1 = − .35, p < .001), but not in wave 3 (w3-w1 = − .06, p = .49) perceived Muslim threat (i.e., after the coup) was lower than in wave 1 (i.e., before the coup). Indeed, the decreased reported perceived societal threat from wave 2 towards wave 3 (w3- w2 = − .36, F(1, 4066) = 59.77, p < .001, \({\eta }_{p}^{2}\)= .01) coincided with an increase in perceived Muslim threat from wave 2 to wave 3 (w3-w2 = .30, p < .001), explaining the lack of significant difference between wave 1 and wave 2 on perceived Muslim threat. The model yielded support for H1b, that the onset of the military coup (being associated with perceived societal threat) coincided with lower perceived Muslim threat and that a decrease in perceived threat in the aftermath of the coup coincided with an increase in perceived Muslim threat (see Fig. 3).
After investigating the temporal relationships between perceived societal threat and perceived minority threat, regression and structural equation models examined hypotheses H2a/ H2b, i.e., whether perceived threat from minorities would mediate the positive/ negative relationship between perceived societal threat and support for minority rights. While we did have measures of perceived ethnic minority threat and perceived Muslim threat in wave 1, we did not possess measures of perceived societal threat or support for minority rights at that time. Therefore, the regression analyses examined H2a/b on data from only wave 2 and wave 3. Measurement of perceived ethnic minority threat and Muslim were randomized between participants, due to survey length constrains. Therefore, two models were constructed, one per mediator.
Multiple linear regression models first tested the paths of the mediation separately, i.e., whether reported perceived societal threat relates to higher vs. lower perceived ethnic minority and Muslim threat and whether perceived ethnic minority and Muslim threat related to higher vs. lower support for minority rights. The analysis showed that those who perceived more societal threat, perceived lower threat from ethnic minorities (b = − .17, SE = .02, CI[-.21, − .13], t = -8.18, p < .001) and Muslims (b = − .16, SE = .02, CI[-.21, − .12], t = -7.90, p < .001) and that those higher on perceived ethnic minority threat (b = − .16, SE = .02, CI[-.20, − .13], t = -8.30, p < .001) and perceived Muslim threat (b = − .13, SE = .02, CI[-.17, − .08], t = -5.77, p < .001) were less likely to support minority rights (see Table 1 and Table 1 in supplementary materials p.1).

Two mediation models tested perceived ethnic minority threat and perceived Muslim threat as 2 separate mediators of the relationship between perceived societal threat and support for minority rights (see supplementary materials p.2). In the first model, besides including perceived societal threat as the independent variable, perceived support for minority rights was taken up as the dependent variable and perceived ethnic minority threat (i.e., the mediator) and the control variables were introduced. In the model, the total effect of perceived societal threat on support for minority rights (b = .17, SE = 0.02, t = 8.44, p < .001) was partially mediated by perceived minority threat as both the direct (b = .15, SE = 0.02, t = 7.29, p < .001) as well as the indirect (b = .03, SE = 0.005, t = 4.83 = p < .001) effect of perceived societal threat on support for minority rights. As a result, this analysis provided support for H2b, that lower perceived minority threat will mediate the positive relationship between perceived societal threat and support for minority rights.
The second mediation model was identical to the first model (see above), yet now with perceived Muslim threat as the mediator instead of perceived ethnic minority threat. In this model, the total effect of perceived societal threat on support for minority rights (b = .15, SE = 0.02, t = 6.97, p < .001) was partially mediated by perceived Muslim threat as both the direct (b = .14, SE = 0.02, t = 6.19, p < .001) as well as the indirect (b = .02, SE = 0.004, t = 3.55, p < .001) effect of perceived societal threat on support for minority rights were significant. As a result, this analysis provided additional support for H2b, that lower perceived realistic Muslim threat will mediate the positive relationship between perceived societal threat and support for minority rights.
Finally, since the list of threats we took up in the survey is arbitrary (i.e., we could have added a series of other threats or left out some of those we have right now), we reanalyzed the data, focusing on the most central item of perceived societal threat. The variable was now conceptualized as whether participants agreed (1 = agree, 0 = not agree) that “the rights and freedoms of the entire population” were threatened by the military coup The results followed the same pattern as the main analyses (indirect effect perceived ethnic minority threat: b = .09, SE = 0.02, t = 4.07, p < .001, indirect effect perceived Muslim threat: b = .06, SE = 0.02, t = 3.35, p = .001).
