All models are reductions, but if yours fits in a 2x2 quadrant, you might have reduced too much.

It's exactly how it started for me and I still can't believe I did it twice. Wonderful conference for speakers, even with less experience, very supportive team and nice people attend, so now you have no excuses :P

It's not that I don't agree, it's more like it's treated somewhat like a mystic text (we all nod solemnly at its profundity) and that it seems like we have little else to say about models. (The essay and talk you did with Rebecca is a rare exception.)

It is misused or misunderstood (I think) to create a narrative of absolute relativity of models.

There is also perhaps a certain facileness in how we talk about models which rubs me the wrong way, which has its roots in the multitude of models and their uses, and also that we seem to be naive about models in general.

It's no deeper than the observation that a linear model is not useful for non-linear systems. But an excessive faith in the relativity of models seem to get in the way of that understanding.

It's also that people seem to read weird things into it, like all models are equally wrong, or all models are equally useful, or all models are useful on the same parameters, or that models are uniformly wrong or useful irrespective of context. I could go on.

To evaluate usefulness, we can't do analysis, we have to put the model to use and iterate. That's the antidote to perfection and paralysis: exist the model to daylight and see if people use it in productive ways.

Well, yes, the quote implies that we don't need to seek perfection, and we don't need to represent all elements from reality accurately in the model. But the second half of the quote tells us to evaluate not perfection (elegance, symmetry, realism...) but usefulness.

Interesting, I always read it differently - to remember that there's something "as good enough for my situation/context" to avoid analysis paralysis and looking for perfection :D

All of the sudden feeling an urge to go to Øredev
Heading soon to @Øredev, exploring how modeling can become a way of leading complexity. 🌿
From work ↔ collaboration ↔ conversation — new modeling fronts will be explored using relational methodology and sociotechnical architecture.

The quote "All models are wrong but some are useful" should not be read as an excuse to stick with your model. It's a call to actively search for more useful models.

I think the thing that is different with chatbots is that they have been shown to have the capability of influencing people's beliefs and behavior. Obviously this isn't a linear deterministic thing, but still, not great.
