That is EXACTLY my experience with Brave Leo and ChatGPT.
They regurgitate woke talking points and memes as if they were accepted reality.
It means they read one set of information sources and treat as gospel. Is that because that set dominates, or is it programming? The references are always like Wikipedia, NPR, NYT, etc. Directed to other sites, it will occasionally acknowledge opposing view points but not without significant prompting and pushback. An unsophisticated user will not realize that and simply take it at face value.
The more you use it the more you see patterns of how it interprets things and you realize that it’s programming.
Push back and accuse it of horrible bias. It comes around. Doing that improves its training set.
