It was put forward in 1960s (maybe? Robert Anton Wilson? and for parallel purposes Philip K Dick's percept / concept feedback cycle) science fiction, and having therefore casually looked for phenomena when support / disprove this hypothesis over the intervening years: that people in power necessarily become functionally psychotic because people will self-select to be around them as a self-preserving / promoting opportunity (sycophants) who cannot help but filter shared observations through their own biases, this is profoundly unsurprising to me.

If you choose to believe as Jaron Lanier does that LLMs are a mashup (or as I would characterize it a funhouse mirror) of the human condition, as represented by the Internet, this sort of implicit bias is already represented in most social media. This is further distilled by the cultural practice of hiring third world residents to tag training sets and provide the "reinforcement learning"... people who are effectively if not actually in the thrall of their employers and can't help but reflect their own sycophancy.

As someone who is therefore historically familiar with this process in a wider systemic sense I need (hope for?) something in articles like this which diagnoses / mitigates the underlying process.
