So we'll start with class for example. I ask myself "Do I find class attractive?" and I can ask myself things like "Imagine a guy with lots of money asks me out. How do I feel?" and "Imagine a guy who has things in common with me asks me out, how do I feel?" If you ask enough questions for compare and contrast, you can get pretty good answers this way.

This type of hypothetical questioning is notoriously unreliable, people ofter come up with answers that don't reflect their actual reactions, If you read closely Yvain's article already gives several examples. It's also one of the methodologies that my psychology teachers highlighted as sounding good, but being largely unreliable.

To make sure I'm not just having random reactions based on how I want to feel, I come up with real examples from my recent past. In the last year or so, I have been asked out by or dated a lot of different people with varying amounts of income. There were a lot of guys who are making 6 figures - this is because I tend to attract well paid IT guys. I liked some of them but didn't like all of them. Some of the guys making 6 figures didn't attract me whatsoever. So income doesn't make me like a guy all by itself.

This is better, but between the general unreliability of memory and the number other factors that would need to be controlled for its still not that great. Particularly since you do feel attracted to men who are more dominate as debaters.
