Intellectual dark matter: What is it, and why is it meaningful?
Throughout history, we find knowledge that can't possibly be documented, but still it exists.
SAMO BURJA: Knowledge rests at the foundation of our society. Knowledge of how to build things like cars, airplanes, nuclear reactors, computers, but also knowledge how to build the companies and governments that allow for things such as cars, airplanes, and nuclear reactors. A failure of these social technologies ultimately results in a failure of the material technologies at hand. A lot of this knowledge, both the physical and the social knowledge is, however, not readily apparent and not easily describable in words. We live in a society that's dominated by bureaucracies. Bureaucracies that have evolved and where people follow rules and procedures that are written down. The vast universe of tacit knowledge, however, shows that there exists an intellectual dark matter all around us that we can't put into writing, can't put into words.
Intellectual dark matter is perhaps very similar to physical dark matter. Most of the mass in our universe is invisible, at least to telescopes, but we know it's there. We know it's there almost certainly because the galaxies are spinning too fast. The stars would fly apart were there not this 85 percent of invisible mass. Looking at society today if we only saw what was written down, what was explicitly laid out, what was explicitly documented on Wikipedia, for example. This could never hold together. This is why we know that intellectual dark matter is out there.
To understand intellectual dark matter you have to understand tacit knowledge and you have to understand technical debt. Technical debt is when someone else solves a very difficult problem be it in code or a manufacturing process or perhaps a philosophical puzzle. You're relying on their solution without even understanding their solution. You're taking these facts and already-built pieces as a given. And on top of them you build something else. It's, in fact, possible to lose this original knowledge. You then end up simply relying on this black box technology that's no longer around. A classical example of this is perhaps that to manufacture a Saturn V engine in say the Apollo rocket would today require a major reengineering effort by NASA.
The thousands of subcontractors that built the individual pieces of the engine even if the engine blueprints are around, those companies are no longer around, and the components would not be built to the same tolerance. So the technical debt that exists in an ecosystem of companies and other organizations and especially very skilled individuals can be very difficult to replicate, can be very difficult to document properly. The second type of knowledge is this knowledge that can't really be documented. How do you describe in words the exact right way to spin during a dance or the exact right way to, you know, throw a basketball into a hoop?
These things matter immensely. A world class surgeon is notably better than a mediocre surgeon for reasons that are almost impossible to put into words. A lot of our great scientific advances arrived out of us formalizing, using mathematics, the implicit and unstated understanding of how the physical world around us behaves. Say how an object falls to something that could be made visible, transparent. In a very real sense every step you might take in transforming the intellectual dark matter of our society into visible intellectual matter. Stuff that's written down that is formalized that is perhaps recorded in video is a step that reduces the fragility of our society.
- You're probably familiar with the concept of physical dark matter, but what about intellectual dark matter?
- In a similar way to the universe's dark-matter makeup, our vast body of knowledge contains a significant amount of information that can't easily be described in words.
- If knowledge was passed down only through writings or direct experience, society would crumble.

Q: Why did the woman cross the road?
A: Who cares! What the hell is she doing out of the kitchen?

A: It doesn't need cleaning yet!
These two jokes represent disparagement humor – any attempt to amuse through the denigration of a social group or its representatives.
Just hearing two languages helps babies develop cognitive skills before they even speak. Here's how - and how you can help them develop those skills.
A new study shows that babies raised in bilingual environments develop core cognitive skills like decision-making and problem-solving -- before they even speak.
Paying a fee for greenhouse gas emissions may spur a revolution, in terms of corporate behavior, amid the climate crisis.
- When it comes to politically addressing the climate crisis, we need politicians from both sides of the aisle to work together to create policies that bring about a more sustainable tomorrow.
- If we enact policies that require companies to pay for their greenhouse gas emissions, we would see an immediate change of behavior from them, in regard to how much they contribute to climate change.
- There's growing agreement that the climate crisis is real among both Republicans and Democrats. The main concern, however, among those who are still critical of its significance is whether it will limit people's choices or slow the economy.
