A study into relations between class, race, and personality

[Azurymber]

Unfortunately, it's all I got that doesn't cost me resources (that I don't have ;-; ) and it's easily accessible to everyone.

If you don't have the resources that's cool. But using an inaccurate test that doesn't provide valid results isn't research.
All you're doing is making up a fake horoscope. Which is cool. But not research.

The reason people find that it "feels accurate" is because it's a biased test that produces the results you expect to get from the answers you choose.
Essentially it's a scam with no scientific basis, designed to trick you into thinking that you are getting accurate insights.

And there are plenty of free personality-ish tests that have some basis in science.
For example the VIA survey of Character Strengths (free to take here: https://www.authentichappiness.sas.upenn.edu/testcenter)
Or the Big 5 personality test (free to take a version of it here: https://www.123test.com/personality-test/)

In fact if you look at the explanation of the test you are using, they mention they tried to bring their old outdated model closer to the big-5 model (which has significantly more scientific backing).

It's great that you want to do research. But if you want it to be meaningful in any way you should put an effort into separating science from fiction.
