The vast majority of these aren't relevant, so you can trim that list a little. Links to 'page not found' aren't relevant, scientific reports discussing how conservatives are on average less intelligent aren't relevant, links to search results themselves aren't useful or productive, and the same study included more than once is certainly not relevant.

Look, the question isn't whether people saying such things (though I think there's a fair argument to be made that not one of these papers at any point says that they think conservatives are "morally inferior"). The question is to compare this to what you would otherwise expect. What will I find if, using the same level of creativity you just used to find evidence, I went looking for "papers" to demonstrate the conclusion that Arabs are on average less intelligent? We both know that, with a creative interpretation of the data, I could find four times this many, right?

Building lists like this isn't productive. Despite the fact that it might feel like it, I don't think it should actually convince anyone of anything.
