The number of exceptional people: Fewer than 85 per 1M across key traits

Cognitive biases can lead to overestimating the expected prevalence of exceptional multi-talented candidates, leading to potential dissatisfaction in recruitment contexts.

Overview of differential geometry for Hamiltonian Monte Carlo
(arxiv.org)
Hamiltonian Monte Carlo has proven a remarkable empirical success, but only recently have we begun to develop a rigorous understanding of why it performs so well on difficult problems and how it is best applied in practice.

An alternative construction of Shannon entropy
(rkp.science)
TL;DR: Shannon’s entropy formula is usually justified by showing it satisfies key mathematical criteria, or by computing how much space is needed to encode a variable. But one can also construct Shannon’s formula starting purely from the simpler notion of entropy as a (logarithm of a) count—of how many different ways a distribution could have emerged from a sequence of samples.

How do countries measure immigration, and how accurate is this data?
(ourworldindata.org)
Debates about migration are often in the news. People quote numbers about how many people are entering and leaving different countries. Governments need to plan and manage public resources based on how their own populations are changing.

The data hinted at racism among white doctors. Then scholars looked again
(economist.com)
BLACK BABIES in America are more than twice as likely to die before their first birthday than white babies. This shocking statistic has barely changed for many decades, and even after controlling for socioeconomic differences a wide mortality gap persists. Yet in 2020 researchers discovered a factor that appeared to reduce substantially a black baby’s risks.

Understanding privacy risk with k-anonymity and l-diversity
(marcusolsson.dev)
Imagine you’re a data analyst at a global company who’s been asked to provide employee statistics for a survey on remote working and distributed teams. You’ve extracted the relevant employee data, but sharing it as-is could violate privacy laws. How can you anonymize this data while ensuring it’s still useful? In this article, you’ll learn about k-anonymity and l-diversity—two valuable techniques in privacy engineering to help you reduce the privacy risk in datasets.

Dispelling Myths about Randomisation
(bps.org.uk)
When we are interested in cause and effect relationships (which is much of the time!) we have two options: We can simply observe the world to identify associations between X and Y, or we can randomise people to different levels of X and then measure Y.

Understanding Gaussians

The Gaussian distribution, or normal distribution is a key subject in statistics, machine learning, physics, and pretty much any other field that deals with data and probability. It’s one of those subjects, like $\pi$ or Bayes’ rule, that is so fundamental that people treat it like an icon.
