Ideologists:

Republicans are more conservative than Democrats

Three Non-Ideologists:

🔹️ "Opposites" - Democratics are more conservative than Republicans

🔹️ "Uniforms" - The two parties are ideologically similar

🔹️ "Ignorants" - Have no opinion

#AcademicSky #SocialPsyc PoliPsy PoliSky PolSciData

We distinguish between ideologists and non-ideologists by comparing the rank order of their placement of two major parties on the ideology scale to the experts’ rank order. Our distinction between the two is based on the examination of the participants’ cognitive consistency (see Ganzach, 2018). The ideologists are those whose rank order corresponds to the “true” (i.e., experts’) rank order (e.g., those who say that Republicans are more conservative than Democrats). The non-ideologists included three sub-groups. The first, which we label the opposites, was described above, (e.g., those who rate the Democratic party in the US as more conservative than the Republican party). The second, which we label the uniforms, include respondents who judge the two parties as being ideologically similar, even though the experts’ judgment is that they are different (e.g., those who say that Republicans and Democrats are equally conservative). The third sub-group, which we label the ignorants, include respondents who do not have an opinion regarding the location of the parties on an ideological dimension (e.g., respondent who answered “don’t know” or “haven’t thought much about this” to the questions regarding the ideological position of the parties).

Every so often reminded measurement in social science takes a back seat to hypothesis testing which isn't great for knowledge accumulation.

Universities like UT Austin have shown that they will place ideology and political power ahead of the most vulnerable students, faculty, and staff they serve.

Fight against the closure of Black, Latino, and Gender Studies at UT Austin. Support our students.

When driver tried to get out, an agent yelled, "DON’T YOU EVER DO THAT AGAIN, I WILL SHOOT YOU"

Do people lie to benefit the in-group and harm the out-group?

In a new paper, we found that people lied 9% more to help in-group members than out-group members! This is evidence of coalitional dishonesty

Democrats & Republicans both lied anonymously to double in-group members earnings (N=5,230)

One important reason why I remain on Twitter is that despite the fact that I use it now primarily to highlight everything that is going wrong in the US and in Mexico, it's still at least a bit cathartic to see everything that a number of US citizens are doing to protest what's happening there.

The Spanish centre-right is taking a tumble and the far-right is on the rise.

I was lucky enough to present some new causal work on Friday at LSE showing that the PP does better when it signals distinctiveness from VOX.

~1.5K tests, same result. Rejecting far-right benefits centre-right
