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, master it today and earn your certification from a Scotland Yard Police detective.

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 short course you will master 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 the key practical 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.

What people are saying

Lee P.

New Zealand

This course was really good. Part new (to me) approaches and part refresher. Well structured and with great examples and resources. In fact, I found the course better than the name of the course suggested. If I may be so bold, I understand that the course leader is ex-police, but I don’t believe the ‘Think like Sherlock’ in the title helps sell it. It is a far better course than that. Jeez, does that make me sound like a pompous, humourless old git? Oh well........

Danté P.

United Kingdom

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.

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!

Andy V.

United States

Loved the story about finding an undercover car thief gang! A great step by step guide to solving problems, shorter and more practical than a book too and thanks for the speedy support when I got stuck.

Maren B.

United Kingdom

Simple to understand, witty and managed to finish it in a day! Two weeks on and has already helped me solve a few problems at work. Thank you Stevyn and well done 42courses!

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.

Mark H.


Took this course while traveling so was happy it worked well on my phone! It was super entertaining and really helpful, if you want to solve problems this is a great course to take, have already recommended it to friends

Monika H.


Großartig. Fokussiert und ohne Chichi,

Blake B.

United States

Fun course with a few real gems!

Paul H.


A great way to find flaws and biases in your own problem solving process.

Nina J.

United Kingdom

I started this course thinking I'd probably already know some of the content. Well, it turned out I knew precious little. Each lesson was a masterclass in logic that seemed simple, yet had only been arrived at after countless days, weeks and years of trial and error. As a result I've come away with some marvellous problem-solving strategies I can put into practice immediately (and indeed shall, just as soon as I've finished writing this!) Thank you, as ever, for another brilliant course.

Aliza R.

This module provides a framework for you to seriously evaluate problems and be less susceptible to human bias. Well worth reviewing.

Gerardo A.


Excelent for solve any problem

Hilary T.


It was an interesting course that was very easy to understand! However, because the talk-to-camera format in the videos were the same, it starts to get a little dry after awhile. Nevertheless, Stevyn is fun to listen to :)

Great insights such as the power of observation, problem script etc. Definitely recommend this course.

Rohan B.


Very practical and easily understood course. It is tough to create something as simple and powerful as this!

Helen N.

United Kingdom

II found some really interesting bits of this course, especially around observation. I have tried doing a running commentary around town and have noticed things I had never noticed before. I have completely scrapped one project and started it again, using mind mapping. I have also restructed my days. I have a lot of free time at present, but I am using it a bit better.

A great new perspective to look at problems. sometimes effective solutions for difficult ( human) problems, are right in front of you that cost very little!

Mohak G.


interesting course to analyze situations and make better choices and analyze the situation

Roberta W.


Great systematic guide to solve issues in the best way forward

pete c.

United Kingdom

great course - helped me pause before sending out a critical email last week. rather than arguing over the merits of various solutions, i forced myself to ask questions and got to a better outcome!

Lara C.


Very interesting course.

Deepti T.


Comprehensive and easy to grasp

Janet C.


some great tips on how to think about problems

Avellar M.


The name of the course alone caught my eye, and it totally delivered on its promise. Recommend it to anyone who wants to think like the greatest detective who ever "lived".

Mateo A.


Think Like Sherlock is the ultimate course for providing Insight in the Problem Solving matter. There is always a different perspective for either interpret or tackle them.
