I think we're gonna find that there are different ways to quantify "humanness" other than IQ. Someone with an IQ of 95 might seem "more real" than an LLM with a computed IQ of 145.
EQ is a much better test at what makes us "human" than IQ. The only reason we don't give it credit is that it makes us even more uncomfortable than IQ.
I mean, yeah. IQ is a bad measure (if self-consistent). Training trumps all, like with every task. The more we do something, the better we'er going to be at it.
The thing that is going to be interesting is now that we have essentially cheap, ethically clear, and realistic digital 'people', what are the experiments that we can do with them and what can we uncover? I'm a little flat-footed even as to the questions that we can ask them now. At the very least, we can use them to 'dry-run' surveys and experiments and have better data collection and stress-testing. Like, you can now generate realistic data now and use that to run the stats while the real surveys are coming in.
