# Explicit model visualizations

What is this about?
===================

I believe explicit model visualizations explain systems better, and if we had the tools to effectively work with them, they could improve the quality of debates and increase rationality in institutions.

In [Lies, Damn Lies and Fabricated Options](https://www.lesswrong.com/posts/gNodQGNoPDjztasbh/lies-damn-lies-and-fabricated-options), the basic idea is that mental models of reality that people hold are often wrong. Not only that, it's hard to estimate just how wrong they are.

In [Prioritization Research for Wisdom](https://www.lesswrong.com/posts/bNffQPeev2peoDWg5/prioritization-research-for-advancing-wisdom-and), the basic idea is that good things happen with wisdom, and we should find ways to be wiser. Wisdom is “the quality of having experience, knowledge, and good judgement”, which basically means “high quality mental models and the skill to use them to achieve the right goals”.

I believe that going beyond simple text explanations will help the creation and support of high quality mental models. We have the tools like rationality and the scientific method for their creation, but little infrastructure beyond linear text to effectively express, share and discuss them. I believe we can build that infrastructure in the form of software tools. 

Such tools can contribute in 3 areas:

*   Useful discussions
*   Rationality in institutions
*   AI (maybe?)  
      
     

Origin of (most) disagreements
==============================

Most (but not all) disagreements in politics and business are not due to core values misalignment, but rather an effect of mismatching mental models of how the world works.

The statement “prosperity is good” is not controversial, but saying “the best way to cause prosperity is capitalism” or “the best way to cause prosperity is communism” is extremely controversial, even though this is one of the most important question of the 20th century.

This is an infrastructure problem

(Even though [conflict theory](https://slatestarcodex.com/2018/01/24/conflict-vs-mistake/) and misaligned incentives exist)

When we compare the two options, like communism and capitalism, we run a simulation using our mental model, and make predictions about how they will contribute to our core values like prosperity. 

Simulations like : “Since people are incentivized to work harder under capitalism, they will be more prosperous” or “Since the greedy elites cannot hoard wealth, median prosperity will be higher under communism”. 

Both of these internally make perfect sense, and both are possible. The real question in this example should be: “how does incentivizing hard work in a capitalist system compare to disincentivizing hoarding in a communist system, in regards to median/average prosperity?”

Now we have a question that has an answer.

If we could accurately depict our mental models, the relationships and weights between the ‘decision nodes’ and how they relate to core values, it would be much easier to figure out the exact points of disagreement, and focus on clearing that up. You can read more and different words about it [here](https://nthlook.wordpress.com/2017/01/14/simple-rationality/) and [also here](https://nthlook.wordpress.com/2017/01/21/quick-modeling-resolving-disagreements).

Explicit modelling
==================

Lets use a famous example to show how explicit modelling would have helped.

The nations of WW1 had a problem - artillery barrages would explode around the trenches, blow up a bunch of rocks, which dropped on the soldiers in the trenches causing head wounds, which is bad. The solution is to wear helmets, which would reduce the number of head wounds. But what actually happened was that the number of head wounds famously increased! There were theories why this happened, like “Soldiers feel safer therefore become less cautious”, with leaders considering recalling the helmets altogether.

  
What was causing this? Let's explain how soldiers get wounded and create a model of what happens during an artillery barrage.  
 

Small rocks hitting heads cause wounds, but medium and large ones cause death.

What would happen if helmets are introduced?

The prediction of this model is that introducing helmets changes the ratio of wound/death scenarios from 1 wound / 2 deaths without helmets to 2 wounds / 1 death with helmets, which is what happened in reality. People looking at the reports falsely assumed helmets had a negative effect, because they  were only looking at wounds but not the deaths. Even if the specific goal failed (reduce head wounds), the decision had a positive effect on the underlying ‘core value’ (our casualties = bad).  
 

With the power of hindsight I knew to draw the correct model which includes deaths. The competing model would be the effect of helmets on soldier carelessness, which would cause more wounds. How to know which one is correct? 

Aside from going into the trenches to see for yourself, you can track all relevant datapoints (wounds, deaths, attacks, etc), and see how a single change impacts them - while this is essentially experimental science, explicit modelling can also help explain the observed changes and find their real causes. 

Do helmets cause soldiers to be careless in a way that causes more wounds specifically to the head but overall die less, or do helmets simply turn would-be-deaths into wounds? The models can also make predictions: “If helmets cause carelessness, then helmet wearers would die to enemy snipers more often”. If that doesn't happen (presumably it didn’t), the 'careless' model is likely worse than the  “Turn death into injury” model, which predicts the number of sniper deaths staying the same as helmets don't stop bullets.

Drawing explicit models in this situation would have revealed other relevant data points, such as deaths, and solve the mystery.  
 

Models in simulations and games  
 
===================================

Building and visualizing models in this way is already common in computer games and simulations. 

In Civilization VI, it's not debatable whether democracy, communism or fascism is the best way to cause prosperity within the rules set by the game. Millions of games of Civ VI have been played, and it's almost provable that in most cases, democracy is best for pursuing a culture victory, communism is best for a space colonization victory, and fascism for a military domination victory.

It's also not debatable whether helmets work inside games, as you know their exact armor rating and other stats.

A game I like for their explicit depiction of models is Democracy(4), where the player is a policymaker trying to optimize policies of a country. 

The model in Democracy is clearly represented. If you want to increase the GDP, you hover over GDP and see a visual representation of everything that affects GDP in-game. There are dozens of policy nodes, and metrics that have an effect. While a 95% income tax would have a directly negative effect on the GDP, in some cases there are many steps or nodes between a policy and its end effects, some of which feed back into one another over time. For example, allowing wire tapping helps crack down on corruption, which results in more business confidence, which results in higher GDP, among a dozen other things. GDP in turn increases the use of technology which increases the annoyance of your citizens over being wiretapped.

  
 

It’s a thing of beauty

Wiretapping, reducing corruption and pissing off liberals  
  
 

Models in games are guaranteed to be correct since its rules and simulations are governed by the model itself (the game just finds an entertaining way to make you aware of it). This is not true for our reality until we figure physics out.

  
  
 

Models in “real life”
=====================

Even though they are not perfectly correct, models and games can still be useful in the real world.  
 

[Taking simplified models](https://sundaystopwatch.eu/taking-a-simplified-model/) is a useful tool for discussion.  
Creating models is directly useful in predictable real world systems like factories, logistics and software architecture.

Neural networks are basically the science/art of creating models, though often not human readable ones, which is a technical problem that may or may not kill us all relatively soon.  
 

I believe that if we had the will and the tools to explicitly create and share models, the practice of modelling could be useful in many fields.

Let's take a look at a debate that often causes a great deal of misunderstandings: “Should we use solar or nuclear power as the primary solution to  climate change?”

The way to approach this via models is to first figure out what the relevant core values are, for example:

*   Environmental impact,
*   Safety,
*   Cost

Then, we would branch out all the relevant aspects of the technology, recursively breaking each thread into separate subthreads until an inseparable ‘atom’ of discussion is reached, and connect them to how they relate to its sub nodes, and ultimately the core values. I call this process atomization.

The environmental impact of a traditional light water reactor comes from:

*   Initial impact (building the reactor)
*   Lifetime operational impact (running the reactor)
*   Managing the nuclear waste

Now that the impact has been atomized into nodes, each can be analyzed and discussed separately. Note that, even though we branched aspects of environmental impact, each of the environment subnodes also relates to cost, but not necessarily safety (building the reactor has low environmental impact, high cost, and no meltdown safety concerns). 

Optimizing the model so it is understandable and reasonably accurate will probably not be achieved on the first try, but that is fine.

This process can be continued recursively, through attaching data and multithreaded discussions to each node and relationship if needed. The environmental impact of building the reactor is not controversial, but nuclear waste is. Recursively branching out the node into smaller, and less controversial claims will eventually force understanding to come out, as misunderstanding will have less places to hide in.   
 

What is the risk if we spread out the nuclear waste in the atmosphere? That would be bad. What is the risk if we store it in a mountain? What is the risk if we store it in this specific mountain? Do we care if some specific area gets uninhabitable if storage fails? Who cares and how much? Can nuclear waste be turned into fuel in the future and be 100% used up so it stops existing and how likely is that scenario to happen?  
 

Most of these question atoms have definite answers.   
 

I’ve had countless discussions about these topics (surprisingly, supporting nuclear or renewables feels like it has a religious zeal attached to it), but only when forcing a system in which extreme depth of discussion is pursued has there been some if miniscule change of opinions. 

  
 

Discuss4Real - useful discussions  
 
=====================================

A method of judging the model quality and intelligibility is needed. 

To facilitate mass participation,  i suggest an in-depth voting system that rates relevant nodes and relationships on 3 axes:

*   Facts true/Untrue
*   Agree/Disagree
*   Good/Bad Explanation

For example, it may be true that nuclear waste in theory is dangerous for a million years, but if someone makes a subnode nuclear-waste  to->  price connection by assuming armed 24/7 guard patrols for a million years, i would label that node and connection as Facts True and Disagree, since the facts and maths are true, but the proposed solution itself is stupid.

This voting system should help steer humans in a more productive direction of discussion, as it will be clearer what exactly is controversial.

  
To recap, the proposed system is software for creating models by selecting “core values”, then recursively atomizing it into distinct nodes and weighted relationships. Visually, the models look similar to previous democracy or helmet examples. Each node and relationship can have its own multithreaded discussion attached so its existence and properties can be questioned and justified. 

Each subnode and its relationships are rated on perceived truth, agreement and quality of explanation so that discussion efforts can be focused on what actually matters. Through discussion-guided changes and iteration, the models get more complex, and hopefully more accurate and less controversial. 

The end product is a robust, fairly accurate, publishable model that clearly shows how an approach (like nuclear or renewable energy) affects the core values.

 In theory, it's impossible to misunderstand each other if using this model, as any source of misunderstanding will be made clear through the use of such infrastructure, and then that specific node or relationship can be further analyzed and discussed.

All of this is a lot of work to use. But imagine what would happen if a system like this gets adopted, and results shared by even a few thousands of users with diverse opinions. By looking up any topic in the public finished model database, You can gain an understanding of the topics model - how different approaches affect the relevant core values, and exactly what is controversial and why, so you can easily update your own mental model with the distilled wisdom of modelling, discussing crowds. 

Ideally, many of the controversial topics will be solved with an accurate model that most relevant people can agree and act upon, thus making discussions more useful. 

  
 

Modelling and rationality in institutions
=========================================

The same infrastructure used differently could alleviate institutional inertia by documenting processes and their requirements/goals so that they can be reevaluated when conditions change.  
 

How do humans make decisions? When faced with a new situation we have no previous knowledge of, we use first principles reasoning, starting from the basics and try to figure out how to combine them to solve some problem. Once a solution is found, it is cached, and the next problem of higher order can be worked on using the cached conclusions. Figuring out the exact movements to walk is hard at first for the baby, but after walking is cached, moving from A to B can use the cached concept of walking without worrying about each and every step along the way.

However, the first-principles conditions that led to the cached decisions change over time. Chattel slavery might have been a cheap method for cotton production in 1700s, but try that shit today and you will find your shareholders very unhappy, because mechanization is cheaper, and societal norms have also changed which would affect your brand image.  
 

First principles thinking is accurate but expensive, and thinking from other cached conclusions is cheaper but runs the risk of cache being wrong. To avoid this, the cache needs to be periodically verified/cleaned… Or better yet, some system should exist to notify you when the conditions for your cached decisions have changed so you can reevaluate them.

I believe that a good portion of  institutional inertia is due to decisions that were good at the time of their implementation, that get grandfathered in and never questioned afterwards. Laws with expiration dates would be an example of clearing the cache to solve that problem, but laws with models, specific goals and explanations on how and why they will be achieved can be better tracked and revised exactly when needed.

If decisions were expressed as models, the exact conditions upon which they rely on would be clear. For car factories, “Since storage costs money, and glass is easy to acquire, we do not need to store glass and will order it so it arrives Just In Time to gain efficiency” while being true, should not be cached to “Just In Time = more efficiency” as it relies on materials being easy to acquire, which may be true for glass but not computer chips, as we’ve seen with the pandemic and the resulting dip in car production.

The same kind of software described in the previous chapter can be used for explicit modelling of institutional decisions, by setting the desired goals and required conditions as ‘root’ values, then branching out decision and process nodes and their relationships from there. Using the JIT example, storage costs money and adds reliability if the thing stockpiled is not easy to obtain from multiple, fungible sources. Should we store glass? No, Since its easy to obtain from many factories. Should we store computer chips? Yes, Since there are only a few factories producing them.

Making an accurate model requires deep understanding of the modeled issue, and initially most simplified models will be wrong. But if enough attempts are made, and skill in doing so is gained, eventually some of those will be useful, and we will know exactly why it is useful so it can be replicated in similar situations. 

To incentivize creating better models, teaching and implementing those models in institutions could be sold as a service by consultants.

  
 

Alignment maybe?
================

If such a system is for institutional decisions, it would generate decision making data, as well as effective and explicit explanations of models. That data could be useful to an AI learning to explain itself to humans, and to make higher level decisions.

Ok, so now what?
================

I tried building the infrastructure to solve this problem in my teens, when I had no skills, contacts or resources, and I mostly learned that those 3 are a positive modifier on my chances to do anything in the future.

The plan was to first use it as a tool for discussions through explicit modelling, then refine it enough  for institutional decision-making. Over time, enough data about explicitly understandable high level decisions would be generated, and testing its usefulness to understandable AI would begin. However, I stopped working on it after Kialo launched (and i had to continue paying rent).  
 

While [Kialo](https://www.kialo.com/) does a… job of supplying discussion infrastructure through multi-threading and voting systems, focusing on debate is treating the symptoms of misunderstandings and not the cause. Analysis, model building and their visualization is in my opinion forcing understanding and avoiding most useless discussion in the first place.  
 

The ideas described in this post seem like low hanging fruit, so its unlikely no one thought of it before. Is there any obvious reason I am not seeing why a system like this will not be useful, except requiring more effort to use?

  
 

The project was called Discuss4Real, and looked cringe.
