Complex Facts

A newsletter of facts and research papers by @victorianoi from @graphext. Complex debates require complex Facts. Let’s find and create better data!

[Complex Facts @complex_facts]

In the last year, I've been saving and categorizing around 20 research papers and analyses per month in my @NotionHQ

This newsletter will make me look deeper, recall, order and connect those ideas periodically to help me shape better opinions and understand this complex world!

The Software Complexity of Nations

Nice economic complexity analysis of open source data. Suggests that software complexity represents a distinct type of competitive advantage and that countries specialise on programming languages related to those they are already capable on.

Delighted to release this paper on Auten & Splinter’s work, painstakingly going through their code & assumptions

We uncover key mistakes—and show that once fixed, their methodology implies the same rise of inequality as in Piketty-Saez-Zucman

When are the most goals scored in a football match?
I’ve been asking myself this question my whole life, and I finally found the dataset to answer it with @graphext , using 44K goals from International football results from 1872 to 2024. Clearly, the chances increase significantly as halftime and the end of the game approach.

[Victoriano Izquierdo @victorianoi]

There's a great indicator for predicting how well a country's economy will develop. It is based on the diversity and originality of the products a country knows how to manufacture and export, which @cesifoti and @ricardo_hausman refer to as the Economic Complexity Index.

For instance, Spain manufactures and exports many different and diverse products, but those requiring more specific knowledge (like car engines) are becoming less original as more countries are learning how to manufacture them, leading to potentially lower margins.

On the other hand, South Korea or Taiwan, despite manufacturing less diverse products, have in recent decades learned to produce new technological products like liquid crystal panels that few countries are currently exporting. Therefore, their economies appear to be more prosperous in the future.

At @graphext, we are making the impossible possible: working with datasets of millions of rows in a browser.

We are looking for programmers who know C++ and/or TypeScript to continue building on top of this impossible front 👇 https://t.co/pMXWa9bivW

Great paper using Lyft data provea racial discrimination against minority drivers in the US controlling by multiple factors

[John A. List @Econ_4_Everyone]

Minorities are stopped more (~30%) and pay more in fines (~30%). Beyond the estimates, our approach can be used to answer related questions and highlights the potential value of private sector data to help inform major social challenges.

Chart-topping original movies have gone extinct. People have a lot of explanations for this, but they're all incomplete because they don't realize the same thing is happening everywhere. An oligopoly has conquered all of popular culture.

I made this personalized doormat for my home using this great strip from Wiley Miller to never forget we live in a complex world with complex answers and our only hope is keep reading and avoid strong opinions

Super interesting paper on Nature using data from Reddit communities they found what communities are more polarized in socio-demographic terms. By @ashton1anderson and @isaacwaller

What communities are you more surprised by?

The US redistributes a greater share of national income to low-income groups than any European country... but access to education and healthcare or labor market regulations might explain why Europe is less unequal.

Yet another example of how crucial is that the state collects relevant data and makes it accesible!
