Donald Hoffman explains how evolution shapes our perception to hide objective reality and instead present a simplified user interface.

Cognitive scientist Donald Hoffman is trying to answer a big question: Do we experience the world as it really is ... or as we need it to be? In this ever so slightly mind-blowing talk, he ponders how our minds construct reality for us.

On “Depressed People See the World More Realistically (2017)”

This reminds me of this amazing TED Talk: Do we see reality as it is? (Donald Hoffman, cognitive scientist) link to this video The intellectual bomb in the video is this: Organisms that perceive only "fitness" drive to extinction all organisms that perceive reality as it is. (in model systems simulating environments and creatures navigating them) My take: at every level, it would seem, perceiving true reality is not favoured. Nevermind cognitive biases, that's just one level. Literally the fabric of the universe: spacetime, matter, language, etc. It means nothing that it might feel comfortable or intuitive -- we should question it all.

On “Ask HN: Words of encouragement for someone lost in life?”

> 0 - link to this video While most of the talk is great, he just handwaves the idea that reality is not "brains and neurons," nor what physicists try to model, but he makes no effort in explaining what's the difference between "reality" and "physics." It would be great if someone who understood that last part could explain it.

The user-illusion metaphor is a central idea in Donald Hoffman's work. I'm not sure who borrowed it from whom. link to this video

On “Hallucination is inevitable: An innate limitation of large language models”

The brain fakes it to approximate reality - more so for reasons of the limitations of the wetware it runs on than anything else. For others here is a TED talk. link to this video

On “GPT-5 is behind schedule”

There's something here that I feel is pretty deep, though offensive for some minds: What is the actual consequence of being wrong? Of not getting right the base reality of a situation? Usually, stasis is the enemy that is much great than false information. If people with 90% truth can take a step forward in the world, even if they mistakenly think they have 100% truth, what does it matter? They're learning more and acting more for that step taken. If the mistaken ground truth is false and importantly enough false, they'll learn it bc their experience is grounded in the reality the navigate anyhow. If they don't learn it, it's of no consequence. This is on my mind because I work in democratic…
