[ODP] The Scandinavian WAIS IV Matrices as a Test of Dutton, te Nijenhuis and Rovaine

#51
I've realized that the paper doesn't justify why Finland is compared to Scandinavia and not say, Germany or Spain? Is it because they are geographically close? Genetically speaking, Scandinavian countries are more similar to Northwestern Europe than to Finland. I think the paper should specify why the author chose to compare Finland against Scandinavia or viceversa, why Scandinavia was compared to Finland and not to another European country.

Another thing: as tentative as my genetic method can be, the Finns have the highest score in Europe on the principal component for educational attainment alleles. See table 2 of my paper: http://figshare.com/articles/Detecting_p...S_/1172301

Perhaps cite this?
It'd be good to have genes for fluid g to compare this with but for now we don't.

Ok, i've made those changes.

Excellent. I confirm my ok to publication.

The new version is good. It contains the changes I requested.

I approve.

However, I hope you will do another analysis when you have more data. Because I'm still half-convinced that finnish people should have higher Gf. The only reason why you find this result is because you have weighted the data set. But the N for WAIS matrices subtest is not small. Generally, I think sampling error is a threat when N is small or very small. That's not the case in your data, so I don't think sampling error is the explanation for the result. The only way to answer this question is to do a follow-up on additional data, and ideally, based on still other test/subtests of Gf type.

Furthermore, I would like you to correct this error :

Quote:To arrive at a single best estimate, we performed a meta-analysis (N-weighted) based both data sets.

The color text for the reference Salmela 2011 is in grey while it should be in black.

And finally, I want to say I don't necessarily like the use of google docs for your drafts. When you modify the draft, the old version(s) is(are) not visible anymore due to the modification/deletion. I prefer to upload all my versions (1, 2, 3, 4, etc.) in OSF, so that everyone can see the progression of my work. I know this journal says nothing about it, but that's my suggestion.

I fixed the missing word "on" and the grey color errors.

Google Drive has versioning (so one can follow the revisions). The trouble is that it is not publicly available. I can see it when I'm logged in, but not when logged out. https://support.google.com/docs/answer/190843?hl=en

Thus I agree that it is a problem, it is also a very useful program.

The entire purpose of the review threads is for people to be able to follow the review process. They cannot do it properly when the old versions are hidden away like this.

On the other have, GDrive is very useful when collaborating on a project where multiple people take part in the writing and fixing of errors as is the case here. This would be much more difficult if one had to rely on uploading new drafts to OSF all the time. GDrive is a more fluid experience.

So what to do? One idea is to make copies of the GDrive document before making major changes to it, so as to have one for each version. This is not optimal in that it will clog up the results when searching in GDrive with copies.

Another idea is to periodically export copies from Drive and save them on OSF. Preferably before any major change. This is perhaps the most reasonable method.

I think before any major change, copies should be saved and uploaded to the forum together with the updated version.

I misstated my idea in the quoted text. I meant uploaded to OSF, not Drive. OSF is better for versioning than forums.

That's a good idea.
