There are a lot of tests which output something distinct from g.

Emotional intelligence would be one example. It turns out having a notion of emotional intelligence is useful. If you take Gardner's 7 intelligence model it turns out that those 7 values don't produce distinct factors in PCA.

The name of the game is finding a new value that robust if you change the test around and that's orthogonal to established psychometric measurements.

That new value might be something that works for various different tests of immunity to mental bias.

Ideally you find something that isn't simple "a * EQ + b * IQ" but that's really orthogonal. Then you can study whether your new measurement is useful to predict things like wealth or educational achievement and whether a linear model that has information about IQ and your new measurement of rationality does better predictions of educational achievement than just a linear model that has information about IQ. At that time you see what the measurement can really do in reality and see whether it's useful.

I don't think that you can say beforehand what success will look like. It's a lot about trying something and seeing whether we get a new number that useful and that bears some relationship to what we call rationality.

I'm pretty sure analysis found that EQ was fully explained by "a * IQ + b * Openness".

Could you link to such an analysis? It would surprise me.

Didn't have a particular source in mind, was going off memory.

Looks like there's some debate over whether it has predictive power, but consensus is that EQ is a collection of mostly unrelated traits, and is heavily entangled with the big five, particularly neuroticism and openness, in an overlapping way. (My memory overstated the case somewhat.) This looks like a relatively representative study, and here are the abstract and docx of a study which concluded that EQ had no meaningful predictive power.

As far as the first study goes, I don't see why we should control for income and marital status. If EQ increases income in a way that increases life satisfaction then EQ is a highly useful construct.

That said there are political problems with treating openness as a variable to be maximized. Openness correlates with voting left in US elections. Teaching people to increase their abilities of emotional management might be politically easier to communicate.

A lot of personality tests are also easy to game if a person wants to score highly. The notion of intelligence supposes that getting high values in the test needs actual skill.
