if you ramp up the production of information, you need better discernment, because your capacity limitations haven’t just magically increased

without better discernment things will break *even if* the quality of the additional information is high ….

it’s not just “AI slop” that’s a problem, just helping regular scientists to produce more is damaging if we don’t simultaneously provide better tools for discernment (human and technical) - but if anything, we are weakening those (e,g. by de-skilling)….

that’s a disastrous feedback loop in the making…

I recently posted a pre-print about reasoning and large-language models....

trying to get that piece on a pre-print server itself was a bit of a journey which illustrates concerns I've had for the last 18 months or so: namely that AI will kill publishing reform.

here a blog post about it:
