Everything said about Joon Sung Park, oldest first

Aug 21, 2026 positive
Assertion Supported
Park: Training on randomized controlled trials improves AI human-behavior prediction
“That by collecting a lot of these randomized control trials that are really well designed, we can make significant improvement in models capability to predict human behaviors.”

Disclosure
Park: Simile aims to build models that replicate human errors
“The models that we're talking about here, what we're trying to create are models that are as dumb as I am, right? So if I make some mistakes, the model has to make the same kind of mistake.”

Insight
Park: Accurate human simulation models must precede complex automation agents
“This technology around simulation, creating accurate representation of people ought to precede the more complex agents that would automate the world that we live in.”

Insight
Park: Training is required for new world physics, while prompting suffices for reactions
“My intuition behind the actual, when do you train or even post train a model versus just prompt a model is if the model has to learn the underlying physics of the world that it's operating in. So it has to learn new social physics. The places where it doesn't …”

Aug 21, 2026 negative
Opinion
Park: Public LLMs lack real human social physics due to web data bias
“I don't think the model has yet, at least the models that are out in the open, has yet learned the complete mapping of social physics of humanity. This actually is one of the core thesis of simile, right? And one of the core reason why that is the case is if y…”

Aug 21, 2026 neutral
Disclosure
Park: Simile always trains separate population-level and individual-level models
“And this is actually what we end up doing at Simile II. We always train two distinct models. One is what we call the population level model. The other is what we call the individual level model.”

Aug 21, 2026 bullish
Assertion Supported
Park: Generative agent digital twins replicate human behavior at 85% accuracy
“And this is where we basically could replicate people's behaviors and attitudes, 85% as accurately as people would replicate their own. So that actually was the first really paper that gave this validated results that we can actually model individuals in an ac…”

Insight
Park: Advanced simulation discovers multi-step paths to achieve a target outcome
“So really what simulation allows you to do in its highest form is you give it not a problem or question, like what would people answer to the survey? That's not what we do. What we tell it is Here is a goal that we have. In the context of foundation, we want t…”

Opinion
Park: No true AI personal assistant exists today despite industry ambitions
“My hot take actually here though, is I don't think we've actually seen a true personal assistant that's actually useful in ways that actually meets the ambition of that particular line of work.”

Aug 21, 2026 positive
Opinion
Park: Facebook data better captures human baseline state than LinkedIn or Twitter
“If we were to look at purely social media, like if you really, you know, if I were, you know, if I had to really pick, Facebook likely is interesting because I actually do think it is most sort of a default version of people because you go to LinkedIn, it's ve…”

Insight
Park: Real decision stakes distinguish behavioral data from attitudinal data
“What makes the difference between what is attitudinal versus behavioral is if the stake in your decision is real. That's ultimately what makes it behavioral.”
