Evolution of the human brain: when bigger is better

[Rynn]

Not really, the current article doesn't go into any detail on their psychology, their history after the first federation period or their relations with other clades, all of which I was able to add to the Yas Om article. Didn't hear any complaints that the article was fine as it was.

The article covers all the key aspects of the clade and goes into great detail on their biology and culture. Just because it doesn't have everything does not mean that it isn't fleshed out. Not every article can cover every aspect of a clade, particularly when clades can be picked up and put down in millions of places across thousands of years of history. Frankly I think you're being a bit rude in assuming that because it doesn't specifically address things that you want to know about that somehow it isn't "fleshed out". Also remember we're talking about an entire clade. Potentially millions of different sophonts use this template across the terragen sphere, as part of wider highbrow communities or just on their own. Talking about their relations with other clades outside of very specific contexts is going to be extremely generalised.

Also, does ai_vin retain a veto on changes to the existing Highbrow article?

We don't have a strict policy but it would certainly be rude to propose needless changes to people's articles (needless as in there is no issue of canon conflict) if they are still active and haven't given permission. If you want to write about a specific highbrow society you are more than welcome to do so without anyone's permission.
