How to Think Like a Detective

- Assume nothing
- Believe nothing
- Challenge and check everything
- use a mindmap
- seek alternative explanations
- recruit a devils advocateDebugging and troubleshooting isn't art or magic, it's just being very boringly methodical and building from the ground up. A single assumption and you're off to a dead end, a single thing taken on hearsay and you will repeat what other people already did, failure to challenge and check will no doubt make you miss something that it crucial to solving the problem.
(That said, it's easy to say in retrospect. In the moment there is always judgement about what to verify first, and of course its always the last thing you check that turns out to be the problem)
Some problems have a single root cause, some have multiple independent root causes, and some issues present when root causes have an interaction type effect.
Probably you could extend your theory to 'first google result for question 'x''.
If we are going to play a game of what you’re allowed to assume and what you aren’t allowed to assume, then you aren’t a detective, you’re a pawn for someone else’s bidding and their strategic movements. Ditto for believing and challenging whatever “facts” you are allowed to believe and challenge.
If you knew the kind of statistics that Pew collects, and how they can be interpreted, you would believe very little indeed.
But if we just keep that aside for a millisecond, doesn't he have a valid point in a way? Isn't it reputational suicide these days to question the popular narrative in many regards? (And yes, let the downvotes roll in, thereby proving my point :))
I learned that what works best is a systematic approach and what works badly is overlooking certain parts to save time based on intuitive assumptions.
I can't count the number of bugs that took me days because I've just jumped to the "heart" of the problem assuming the rest that got me there was fine. Only to have someone else looking at the problem with less knowledge, going through tings that seemed mundane but who finally gave valuable hints even if they were not problematic themselves.

By the way, there is a section of the article where they mention books:
The book Blackstone’s Senior Investigating Officers’ Handbook (5th ed, 2019) by Tony Cook is a unique one-stop guide to all the processes and actions involved in conducting major investigations, presented in a clear and understandable fashion.
For my PhD thesis The Making of an Expert Detective: Thinking and Deciding in Criminal Investigations (2016), I drew on theoretical frameworks developed in social and cognitive psychology to examine the degree to which individual and systemic factors can compensate for inherent biases in criminal detectives’ judgments and decision-making.
The book The Routledge International Handbook of Legal and Investigative Psychology (2019), edited by the psychologists Ray Bull and Iris Blandón-Gitlin, explores contemporary topics in psychological science, applying them to investigative and legal procedures. Featuring contributions from recognised scholars from around the globe (including myself), it brings together current research, emerging trends, and cutting-edge debates in a single comprehensive and authoritative volume.
The book Superforecasting: The Art and Science of Prediction (2015) by the political scientist Philip E Tetlock and the author Dan Gardner offers a deeper insight into prediction, drawing on decades of research and the results of a massive, US government-funded forecasting tournament. The Good Judgment Project involves tens of thousands of ordinary people – including a Brooklyn filmmaker, a retired pipe-installer, and a former ballroom dancer – who set out to forecast global events. Some of the volunteers have turned out to be astonishingly good. These ‘superforecasters’ have beaten other benchmarks, competitors and prediction markets. They’ve even beaten the collective judgment of intelligence analysts with access to classified information.
‘Correlation does not imply causation’: for decades, this mantra was invoked by scientists in order to avoid taking positions as to whether one thing caused another, such as smoking and cancer, or carbon dioxide and climate change. But today, that taboo is dead. The causal revolution has (seemingly) cut through a century of confusion, and placed cause and effect on a firm scientific basis. The Book of Why (2018) by the computer scientist Judea Pearl and the science writer Dana Mackenzie explains causal thinking to general readers, showing how it allows us to explore both the world that is and the worlds that could have been. It is the essence of human and artificial intelligence. And just as these scientific discoveries have enabled machines to think better, The Book of Why explains how we too can think better. ```
A previous request clued me into “Freedom of the Hills” and “The Mariner’s Weather Handbook”
“ The most complete guide to marine weather analysis, tactics, and storm avoidance. Teaches traditional forecasting based on current observed conditions, as well as the latest tools including facsimile charts and the Internet. An easy-to-use tool for sailors, power boaters, professional seamen, and anyone interested in the weather.”

soThe Thinkers Toolkit - this has some good techniques for breaking down problems and how to structure your questions.
Structured Analytic Techniques for Intelligence Analysis - This is I guess more of a textbook for teaching people how to structure analysis and provide some insights in how to approach and analyze different problems.
It’s surprising usually how little they actually figure out. It takes 2 more murders to help them along. It’s just fiction but it’s probably not far from the truth
