[ODP] Are stereotypes about immigrants accurate in Denmark?: a large, preregistered

#10
This is a lege artis conducted study and a very well prepared paper.

Some points can be improved in the manuscript and some aspects in further studies.

First, there is nearly no introduction and no theory. Its a very Ockham-British-Lynn like data driven paper. More verbalization and generally a better formatting of ODP papers would be helpful.

Next there is a lot of statistical analysis and it seems the authors have analyzed all what is possible to do with the given data. However, data analysis should be driven by research questions and theory.

Introduction: You wrote “stereotypes were moderately accurate (median correlational accuracy score = .51)”. Usually, taken Cohen’s levels for interpretation r=.10 is a small correlation, .30 a medium and .50 a large correlation. For the validity of tests r=.50 is taken as a large correlation (Fisseni).
Cohen, J. (1988). Statistical power analysis for the behavioral sciences. Hillsdale, NJ: Erlbaum.
Fisseni, H.-J. (2004/1997/1990). Lehrbuch der psychologischen Diagnostik. Göttingen: Verlag für Psychologie.
However, for reliability measures higher correlations are expected (r=.80 medium, r=.90 high; Fisseni). And as I remember averaging Jussim’s (2012, his tables 17-1 to 17-3) results the average correlation between stereotypes and criteria is about r=.81.
So you should discuss possible benchmarks/norms and justify your taken benchmark for interpretation.

I see two aspects that could be improved in the survey hopefully possible in a future/further study:

1. Disclosure. You start your questionnaire (translated to English) with:
“When people have expectations about how one or more groups are or behaves, it’s often called a “prejudice” or “stereotype”. Often it’s said that they are inaccurate, even without examining this. The purpose of this study is to examine how precise the Danes’ stereotypes of immigrants are. Which is why we ask of you to evaluate how well a plethora of immigrant groups in Denmark perform, without looking up the numbers beforehand.”
In this way the surveyed persons know what is going on and that may bias their answers and your results. You should better frame it more neutrally and bend thoughts [distract] from the stereotype subject.

2. Ask more questions. Not only ask about migrants and public assistance (welfare), but also about crime and about divorce and family stability or production of jobs (anything positive on immigrants) or student performance. And a totally different subject as differences between men and women.

In the paper itself the question has to be mentioned, this is central! Currently the paper cannot be understood. (“People who live in Denmark originate from many countries. We would like you to evaluate how many people among the 30-39 year olds that you think are on public assistance, from each country of origin.”)

Very, very good: Your control questions and the procedure to clean the data. This is exemplary!

Always add page numbers in manuscripts. Always add page numbers in by Open Psych published papers. Papers should be finally formatted as usual by professional publishers (Cambridge, Elsevier, Sage, Springer). The more professional the better.

I do not understand the utility of the analyses in chapter 6 (“Inter-rater agreement”). Start your analyses and paper with theory and research questions and then add only the necessary analyses.

Very good and important: What predicts stereotype accuracy. Here you found that conservatism leads to higher accuracy of judgments. However, in areas of lefty questions (e.g. gender differences) maybe progressivity would lead to better stereotype accuracy.

As far as I remember also Lee Jussim has done some analyses on predictors/determinants of stereotype accuracy. Compare your results with his results and bring it in the introduction and discussion.

Table 5 in chapter 7.1: Never bring abbreviations – I do not understand what means “DF” etc.

Below Figure 6 (why there are no page numbers?): d=.19 has to be written as d=0.19. Values (p, r, usually beta) which can be only between 1, 0 and –1 write as “.19”, values that can be larger (d) write as “0.19”.

Finally, choose different outlets. Also include standard APS, APA and Elsevier journals.
