Episode notes

Why do smart people make bad decisions?

Every day, intelligent people make decisions they later regret.

People with knowledge, experience, and access to more information than ever before — yet intelligence alone does not guarantee better decisions.

In the first episode of The Thinking Behind, we explore one of the biggest contradictions in human behaviour:

If intelligence helps us think better, why do intelligent people still make irrational choices?

This episode explores the hidden systems behind our decisions — the beliefs, emotions, experiences, biases, and assumptions that influence how we see the world.

In this episode, we discuss:

• Why intelligence is not the same as rationality

• How confirmation bias shapes our beliefs

• Why memorable events can change how we judge risk and probability

• How the sunk cost fallacy keeps us attached to past decisions

• How to build better thinking systems

The question is:

Are we seeing reality clearly — or are we seeing reality through the filters created by our own minds?

Welcome to The Thinking Behind — a podcast where we explore the ideas, decisions, and mental models behind human behaviour, businesses, technology, and the world around us.

About The Host

I'm Swarndeep Khatri.

I have always been curious about one question:

"What is the thinking behind how things work?"

Whether it is human behaviour, businesses, technology, science, or everyday decisions — I am fascinated by understanding the patterns and principles that exist beneath the surface.

Through The Thinking Behind, I explore conversations and ideas that help us understand why people think, decide, create, and succeed.

This journey begins from Ranchi, Jharkhand, with a simple goal:

To understand the thinking behind everything.

Think better. Decide better. Build better systems.
