The story behind Brain Bugs
Kasra Mojtahedi — leadership psychology, cognitive bias, and behavioral economics expert

For over 15 years, I've had a front-row seat to how smart people make costly mistakes.

As a Partner at one of the world's largest consulting and accounting firms, I've spent my career in the trenches of corporate transformation — leading enterprise restructurings, mergers, technology implementations, and large-scale strategy initiatives across industries, government institutions, and NGOs.

I'm a CPA, a technologist, a venture investor, and a senior advisor who has built teams, businesses, and guided some of the most complex organizational changes at the highest levels. Through all of it, one thing has become undeniably clear: the biggest risk in any room isn't the strategy — it's the psychology.

I've watched brilliant executives fall into the sunk cost trap. I've seen seasoned leaders paralyzed by analysis paralysis. I've witnessed confirmation bias silently derail million-dollar decisions — sometimes multiple traps compounding at once into what Charlie Munger called the "Lollapalooza effect," a perfect storm of psychological forces that takes down even the sharpest minds.

Munger's legendary Harvard speech on the 25 causes of human misjudgment was the spark that lit this project. Brain Bugs is my way of putting these behavioral economics and psychology insights into the world — not just for boardrooms and business leaders, but for anyone navigating careers, relationships, personal finance, and everyday life decisions.

Every bias has a pattern. Every pattern has an antidote. I'm building a library of mental models — practical thinking tools you can use to recognize these traps before they recognize you.

My mission is simple: help leaders, professionals, and self-improvement seekers see what they normally can't — so they can think clearly, decide wisely, and thrive in business and life.
