Learn how to solve problems from a Scotland Yard Police detective

“We need more cops like Stevyn Colgan! A model of smart storytelling, cunning insight, and pure inspiration.” - Stephen J Dubner, co-author Freakonomics and Superfreakonomics

Problem solving is a skill that is in high demand.

Despite the fact that we face many problems in both personal and professional life, we are never taught at school or even university how to solve problems effectively.

In this course you will learn about the problem solving process used by a highly experienced Metropolitan Police detective who spent 30 years solving real problems on the streets of London.

You will also learn about a variety of techniques to vastly improve your ability to solve problems as well as tips for how you can put yourself in the right mindset. At the same time, you will be introduced to some of the common pitfalls made in decision making and how best to avoid them.

By the end of this course, you will be equipped with the skills and knowledge you’ll need to solve problems just like Sherlock.

The secrets to effective problem solving lie just a click away.

“Intelligent and humane”Prof Richard Dawkins

“Stevyn took lateral and creative thinking and applied it to bigger social problems. I think there’s a huge opportunity for that kind of thing” - Rory Sutherland, Ogilvy Vice Chairman

Stevyn Colgan

Stevyn spent 30 years in the Metropolitan Police Service.

Twelve of those were spent as part of Scotland Yard’s award-winning Problem Solving Unit, a specialist team with an extraordinary brief: to solve problems of crime and disorder that were unresponsive to traditional policing methods.

Since retiring he has been one of the writers of the BBC TV series QI and its sister show on BBC Radio 4, The Museum of Curiosity. He has also found time to write seven books and is a regular speaker at events such as the Edinburgh Festival, the Hay Festival, QEDCon and Latitude.

Stevyn has appeared on many podcasts and radio shows including Freakonomics, No Such Thing As A Fish, Little Atoms, to name just a few.

If you haven't come across Stevyn you're in for a treat. He's a delight to learn from, his wit and brilliant storytelling make this really this super easy to learn from. The tools shared helped me to solve problems at work and in my personal life much more effectively. Bravo Stevyn!

Danté P.

Wow, so many interesting stories and useful tactics in this course, I can see why he worked on QI (also love how many books he has behind him in the video!!!!). If you want a fun and easy way to learn how to better solve problems then give it a go.

Aiden C.

I hadn't heard of Stevyn before this but glad I gave this a go, I wanted a way to better solve problems at work and Stevyn's insights and methods definitely helped me find some innovative new ways to solve them. It's incredible how broad you can use these tools in life, they pretty much work for any issues you may be facing and they are super easy to use, it's almost like I have a new way of looking at the world...not quite Sherlock Holmes in the BBC TV series level, but close enough.

I always thought it was strange that problem solving was never taught at school. I mean we all face problems everyday. Stevyn was a brilliant teacher and the course was both fun and very informative. The story about the noisy nightclubbers and lollipops was genius! So good!

Magda B.

United Kingdom

Really enjoyed this course. I liked it because I learnt a process for solving problems as well as a whole bunch of useful techniques to make me a better problem solver. It was interesting learning from a former police detective too and some of the real world examples were brilliant.
