^ thats the first 12 most populous countries in the world, i didnt list US, which is the only one among those that ranks with individualism higher than 50%. Vast majority of human cultures/societies are highly collectivist.
It missed Russia. Russia is #9. Doubt it would be "individualist" though. And even less likely to be "egalitarian" vs "authoritarian".
Anyway, for traits, you have to think how humanity would compare to "average of all sentient life throughout the galaxy" which is impossible, since if there is sentient life in the galaxy, we don't know anything about it.
But, since the baseline in the game is that your home planet population can go from 8 billion to 16 billion in no time, I'd say humans are slow breeders compared to that.
Also, we live on all biomes on earth, but a whole arid planet or tundra planet? I think that'd be tough for us without some better tech. Adaptive, but not highly adaptive.
Anything else, which doesn't establish baseline numbers, is tough. Strong cases for resilient (which is, unfortunately, a useless trait in this game) and communal and deviant and nomadic. Maybe not nomadic, but definitely not sedentary. I really think communal, but definitely not solitary. I could easily see the case for conformist vs deviant, just impossible to gauge without a baseline...
As for ideology, in this game that's not race specific at all, every race drifts everywhere, they just start somewhere based on their dominant government when they become spacefarers. In 1.5 it seems like traits will actually influence where you drift, somewhat.
Where is humanity right now? Most governments are authoritarian, but not fanatic about it, the fanatic usually fade or adjust quickly. I'm not sure most people are authoritarian (hence deviants). I think we tend towards xenophobia (we'll eat your food if it's tasty but don't come over here and try to marry us!) Definitely militaristic (pacifism is a new thing brought up thanks to world wars, our closest evolutionary cousins rip each other's faces off.) Definitely inherently spiritualist (we are biologically wired to have religious experiences, more useful back when we didn't know anything, and as we drift towards materialism some people are trying to violently pull us back.)
I'd go militarist xenophobe, then either authoritarian or spiritualist, as kinda our "default". Geez, we suck huh? Nah, we're still good empathetic people, just sometimes let our instincts get in the way.
