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

#18
Heiner,

Thanks for reviewing.


Quote: Typo, p. 15: Tho individuals

Fixed.

Quote: The distinction between individual and aggregate accuracy is now clear. (It is similar to inter-rater reliability: While individual agreement between two randomly chosen raters is low, about r=.20 to .30 for students’ evaluations of instruction, the ”reliability” or ”objectivity” of the mean of two raters is about r=.25 to .35. It can be simply calculated using Spearman Brown formula – the more raters, the higher the reliability-objectivity of the mean of raters.)
 
However, it is still not clear what they mean.
 
I suggest to add sentences similar to those (write in your own words!):
 
Individual stereotypes represent the thinking of a single person. Individual accuracy stands for the accuracy of the thinking of an average single person, here about immigrants. However, this is not what is really interesting. Much more important is the accuracy of collective thinking, the accuracy of generally shared stereotypes. If the term ”stereotypes” is applied, usually not stereotypes of single persons are meant but in a society widely spread patterns of thinking influencing individuals in their thinking and behavior, e.g. about sex differences in mathematics vs. language or about differences in ability and crime between races. These are the relevant stereotypes, the collective ones. They impact society and culture and the people. We use for them the term aggregate stereotypes and the aggregate accuracy stands for the accuracy of the typical thinking in society.

I rewrote part of the Discussion to be:

We observed relatively high levels of accuracy. The accuracy for aggregate stereotypes was much higher (r = .70) than the median individual accuracy (r = .48) as expected based on the Spearman-Brown formula. In thinking about stereotypes, the aggregate stereotypes are usually the important ones to focus on. This is because these represent the typical or average expectations of the population. The beliefs and any resultant actions of single persons average out with each other.


In general, the present results are similar to those found in the pilot study. The only findings that did not replicate were the strong predictive validities of age and gender observed in the pilot study.

The findings fit well with the general literature on stereotype accuracy (Jussim, 2012; Jussim et al., 2015). The average correlation in social psychology has been estimated to be around .20 (Richard, Bond, & Stokes-Zoota, 2003),1 while we found that 78% of participants had accuracy correlations above .30 and 45% had scores above .50. Previous studies of racial/ethnic stereotypes reported average accuracies between .36 to .69 and .53 to .93 for individual and aggregate-level stereotypes, respectively (Jussim, 2012, p. 327).

[foot note]
1This value is very likely to be too large. The estimate is based on a large number of meta-analyses which mostly did not correct for the endemic publication bias in this field (Open Science Collaboration, 2015).

Let me know whether this is satisfactory.
