Gupta European Programme

Before taking off, participants will attend various inhouse days in the Netherlands. During the trip, we will visit several companies with the aim to experience the business culture. The companies differ greatly in their specialities and will shed light on how econometric study skills can be applied abroad. Naturally, there will also be plenty of time to discover the amazing attractions our location has to offer.

Simpson's paradox: when more data leads you astray

28 october 2025

Imagine you are evaluating the effect of a job training program across genders. In both men and women separately, the program seems to help; but when you pool the data, the effect vanishes or reverses. That’s not just annoying, it can completely mislead your inference if you don’t look out for lurking variables. Welcome to the simpson’s paradox, a really weird and frustrating statistical phenomenon.

The Balance Within Chaos

21 october 2025

Imagine a simple pendulum: a weight hanging from a fixed point. When it hangs straight down, it is perfectly still. This is its point of stable equilibrium, the position it naturally returns to whenever it is moved. Push it gently to one side, and it swings back and forth, trading height for speed, before slowly coming to rest again. Even while moving, it stays in balance because the forces acting on it work together.

Why negative feedback is better for improvement (or is it?)

14 october 2025

In the years after World War II, a group of Israeli Air Force instructors believed they had discovered a hard truth about human nature. They noticed something strange during flight training. When a pilot executed a perfect maneuver and received praise, the next attempt was usually worse. But when a pilot performed badly and was harshly criticized, his next flight tended to improve. It felt like solid evidence. Praise seemed to weaken people, while criticism toughened them up. Many instructors became convinced that tough feedback was the only way to improve performance. The conclusion was neat, logical, and entirely wrong.

The Edge of Logic: Reflections on Gödel’s Incompleteness Theorems

24 june 2025

In the early 20th century, a young Austrian logician named Kurt Gödel did something remarkable. He proved a pair of theorems that would shake the foundations of logic and forever alter how we think about truth. These findings, now known as Gödel’s Incompleteness Theorems, revealed something deeply unsettling: in any reasonable formal system powerful enough to describe basic arithmetic, there will always be true statements that cannot be proven within the system itself.
