  [ODP] The Black White IQ gap in the total sample of the Vietnam Experience Study

Title:
The Black White IQ gap in the total sample of the Vietnam Experience Study

Abstract:
IQ differences were examined between Blacks and Whites in a large Vietnam era sample (Vietnam Experience Study; total n ≈ 10,800). Relative to a White IQ of 100 and SD of 15, Blacks obtained a mean IQ of 85 and an SD of 12.
An attempt to examine measurement invariance using multi-group confirmatory factor analysis failed with impossible estimates and very poor fits. A simpler approach of examining the correlation matrices by group showed that the White correlations were stronger, sometimes by a lot. Possible reasons for this were discussed.

Key words:
Black, White, Vietnam Experience Study, race difference, IQ, intelligence, cognitive ability, measurement invariance, multi-group confirmatory factor analysis, MGCFA

Title:
Immigrant crime in Germany 2012-2015

Abstract:
Number of suspects per capita were estimated for immigrants in Germany grouped by citizenship. This was correlated with national IQs (r=-.53) and Islam prevalence in the home countries (r=.49), congruent with other studies. Multivariate analyses revealed that there was a confound with the mean age and sex distribution of the groups in Germany.
The German data lacked age and sex information for the crime data and so it was not possible to adjust for age and sex using subgroup analyses. For this reason, an alternative adjustment method was developed. This method was tested on the detailed Danish data which does have the necessary information to carry out subgroup analyses. The new method was found to give highly congruent results with the standard subgrouping method.

The German crime data were then adjusted for age and sex using the new method and these were analyzed with respect to the predictors. They were moderately to strongly correlated with national IQs (.46) and Islam prevalence in the home country (.35). Combining national IQ, Islam% and distance to Germany resulted in a model with a cross-validated r2 of 20%, equivalent to a correlation of .45.

We will try to recruit a German reviewer. David Becker is the student of Heiner Rindermann, so he will not be a suitably impartial reviewer.

Title:
Name features and social status: an exploratory study of 1,890 Danish first names

Abstract:
A dataset of the relative social status of 1,890 first names of persons living in Denmark was obtained from a previous study. Linguistic features were generated based mostly on n-grams augmented by regex and each name was scored on each feature. The list of features were then pruned based on their presence in the data such that features that never or almost never appeared in the data were discarded. An initial check using t-tests showed strong signal in the features taken as a whole and that this was due mostly to low status names being more similar. LASSO regression was then used to select a subset of features with above chance level validity. Finally, an OLS model was fit based on the LASSO chosen features. This model showed a cross-validated R2 of .40, equivalent to a correlation of .63. It was concluded that subtle linguistic features in first names have substantial validity for predicting relative social status in Denmark.

Title:
Criminal and antisocial behavior and cognitive ability in a sample of dating site users

Abstract:

The relationship between cognitive ability and a broad variety of criminal and antisocial (CAS) behaviors was examined in a sample of dating site users. Cognitive ability was scored from 14 suitable items using item response theory. 11 of the 13 items were negatively related to cognitive ability with latent correlations ranging from .01 to -.29, and a median of -.14. Correlations for males were stronger with a mean/median male/female ratio of 1.7/1.4.

The CAS items were all positively correlated (mean correlation = .23) and formed a general CAS factor. Attempts were made to use item response theory to score this factor, but results proved unsatisfactory. Instead, a simple score was calculated by summing the items. This score correlated -.16 [-.14 to -.18] with cognitive ability.

To examine the influence of confounders, an OLS model was fit using cognitive ability, gender, age, and cognitive ability x gender as predictors and the simple summed score as the dependent. In this model, the standardized beta cognitive ability was -.19. A series of robustness checks were made using alternative model specifications which provided near identical results.

Key words:

crime, antisocial behavior, violence, cognitive ability, IQ, intelligence, dating site, gender, sex

  [OQSPS] Cognitive ability and political preferences in Denmark

Title:
Cognitive ability and political preferences in Denmark

Abstract:
We investigated the relationships between cognitive ability and multi-dimensional political preferences in a recent Danish sample (n = 320). Respondents answered 10 questions pertaining to specific social issues, 10 questions pertaining to specific economic issues, as well as taking 4 cognitive items. They had previously taken a 5-item cognitive test (ICAR5), and been asked to rate themselves on social liberalism and economic liberalism. We documented a general factor of social liberalism across the questions on social issues, and a general factor of economic liberalism across the questions on economic issues. Self-assessed social liberalism had a small positive correlation with measured social liberalism (r = .12), while self-assessed economic liberalism had a moderate positive correlation with measured economic liberalism (r = .47). These findings were in line with our predictions. Contrary to our predictions, however, social liberalism and economic liberalism had a weak positive correlation (r = .10; 95% CI = [–.04, .22]) and cognitive ability was practically unrelated to both social liberalism (r = .06; 95% CI = [–.07, .19]) and economic liberalism (r = .05; 95% CI = [–.08, .18]).

Note that the questionnaire is currently not available. It will be made available shortly (pending email reply from the survey handler).

External reviewers:
We will attempt to recruit an external reviewer who's familiar with this area. Perhaps Peter Kurrild-Klitgaard. Prof. Pol. Sci. @ Copenhagen Uni. http://forskning.ku.dk/find-en-forsker/?...sons/63119

Since this paper has two of the internal reviewers familiar with this topic, we probably need to recruit an additional temp. external reviewer or a new internal one.

Status
The results in the paper are not final because we are still collecting a little bit of data (perhaps 30 more cases). However, it is very unlikely that they will substantially change. For this reason, the numbers in the paper are temporary and will be updated.

The tables are temporary. Julius will typeset the paper in LaTeX, so there is no reason with bothering to make the tables in Word pretty. But they should be readable for the sake of review.

  How to submit
Posted by: Emil - 2014-Mar-08, 17:16:48 - Forum: Submissions - No Replies

To submit a paper, simply start a thread with the paper. Detailed instructions below.

Formatting
We focus on the science, not the formal requirement. We don't want scientists to spend more time formatting papers than writing them. For this reason we have minimal requirements for formatting. Basically, it should look like academic writing. Use any reference system you like, as long as it is sensible.

However, Google Scholar has certain requirements for indexing papers properly. Authors are recommended to follow these requirement as it will ease the indexing of their own work.

To summarize, they are:

  1. Font size 24 for title.
  2. Font size 16 for authors.
  3. No author affiliation on the same line as authors (use footnotes).
  4. Include a citation of the paper itself in the header.
  5. Use only the major reference formats. They seem to prefer numbered references instead of APA-style (name, year).
Templates:
The journal's OSF repository has templates in .docx, .odt and .tex formats.

Submissions
To submit a paper, create a thread with the paper and the supplementary material.

Thread titles must have the format: "[journal abbreviation] Title".

Journal abbreviations are:
  • [ODP] - Open Differential Psychology
  • [OBG] - Open Behavioral Genetics

Example submissions title: "[ODP] Predicting Immigrant IQ from their Countries of Origin, and Lynn's National IQs: A Case Study from Denmark"

The post must contain the draft either in text or via link to some readable major format (.doc(x), .odt, .html, .pdf).
The post must contain the abstract.
The post must contain the data.

We prefer that authors use Open Science Framework to host their submissions, code, data and other files. This enables easy management of files and revisions (versioning). It makes it easier for reviewers and others to follow each file as it was in different stages thruout the submission-revision process.

Revisions
Usually, reviewers will request changes or find errors in the paper. Authors can choose which criticism to adhere to, but they should remember that they will need to satisfy a number of reviewers to gain acceptance for publication. When submitting a revision, please make a reply post in the submission thread instead of updating the original post with a new file.

There are two reasons for this. First, this results in the thread marked marked as 'active' which tells reviewers that something has happened in it. This does not happen when one only edits a post. Second, it means that the entire review history can be followed. If one updates the file instead, then the older drafts are no longer available. Optimally, authors should use Open Science Framework to handle the files.
