Investing Psychology by Tim Richards: Why Your Brain Is Bad With Money
I just finished reading “Investing Psychology: The Effects of Behavioral Finance on Investment Choice and Bias” by Tim Richards. And I need to talk about it.
Investing Psychology
Tim Richards' guide to behavioral finance biases that sabotage your investment decisions and how to fight back.
Investing Psychology takes decades of academic research on behavioral finance and makes it accessible to regular investors. Tim Richards, who spent years writing about these topics on his Psy-Fi Blog, breaks down the cognitive biases, emotional traps, and social pressures that cause smart people to make terrible money decisions.
The book covers nine chapters organized around different sources of bias. It starts with sensory biases - how our brains see patterns that don’t exist and make predictions based on nonsense. Then it moves to self-image problems like overconfidence, loss aversion, and anchoring. The middle chapters tackle situational and social influences - herd behavior, groupthink, framing effects, and how the financial industry exploits all of these biases for profit.
The second half shifts from diagnosis to treatment. Richards examines professional bias (even fund managers aren’t immune), debiasing strategies, and a practical 7-step framework for “good enough” investing. The book wraps up by busting 10 common money myths and delivering final takeaways you can actually use.
This is for anyone who manages their own money and wants to understand why they keep making the same mistakes. No finance degree needed. Richards writes with humor and honesty, backing up every point with real research while keeping things readable and practical.
Investing Psychology Chapter 1: How Your Brain Tricks You About Money
Previous: Intro post
Chapter 1 of Investing Psychology is called “Sensory Finance.” And it starts with a punch to the ego.
Investing Psychology Chapter 1 Part 2: Herding, Hot Hands, and Mental Shortcuts
This is Part 2 of Chapter 1 from “Investing Psychology” by Tim Richards. If you missed the first part, go read Chapter 1 Part 1 first. We covered how your senses trick you. Now we get into how your brain takes shortcuts and how other people’s behavior messes with your money.
Investing Psychology Chapter 2: Overconfidence, Loss Aversion, and Your Ego
Chapter 2 of Tim Richards’ book is called “Self-Image and Self-Worth.” And the title tells you everything. This chapter is about how your ego quietly destroys your investment returns.
Investing Psychology Chapter 2 Part 2: Emotions, Black Swans, and Getting Nudged
In Part 1 we talked about overconfidence, loss aversion, and the disposition effect. Now let’s keep going with the rest of Chapter 2. This part gets into emotions, Black Swans, mental accounting, and some practical ideas on how to not sabotage yourself.
Investing Psychology Chapter 3: How Your Situation Changes Your Money Decisions
Previous: Chapter 2 Part 2
You survived your own ego in Chapter 2. Good job. But here’s the problem. Even if you fix your overconfidence, your environment can still ruin your investing decisions. Chapter 3 of Tim Richards’ book is all about situational finance. The idea that the world around you pushes you into decisions you think are your own.
Investing Psychology Chapter 3 Part 2: Mood, Persuasion, and Market Anomalies
Previous: Chapter 3 Part 1
We’re still in Chapter 3 of Tim Richards’ “Investing Psychology.” In Part 1, we covered how situations mess with your head. Now let’s talk about something even weirder: your mood, the weather, and why shouting “Fire!” in a theater is basically what happens during a market crash.
Investing Psychology Chapter 4: Social Pressure, Groupthink, and Framing
Chapter 4 of Investing Psychology is where Tim Richards talks about something we all deal with but rarely notice: other people messing with our financial decisions. Not on purpose. Just by existing around us.
Investing Psychology Chapter 4 Part 2: Trust, Language, and the Social Side of Money
In Part 1 we covered how groups and social pressure mess with your investment decisions. Now let’s get into something even sneakier: how language, trust, and social networks warp the way we think about money.
Investing Psychology Chapter 5: Why Even the Experts Get It Wrong
When we get sick, we go to a doctor. When something breaks, we call a professional. So when it comes to investing, we hand our money to financial experts. Makes sense, right?
Investing Psychology Chapter 5 Part 2: Corporate Bias, IPOs, and Hidden Trading Costs
We continue with the second half of Chapter 5 from Tim Richards’ “Investing Psychology.” If Part 1 was about how the professional investing industry takes your money, Part 2 is about how corporations and your own trading habits finish the job.
Investing Psychology Chapter 6: Fighting Your Biases With Better Strategies
Chapter 6 is called “Debiasing.” After five chapters of telling us how broken our brains are, Richards finally starts talking about what we can actually do about it. The short answer: there is no magic fix. But there are tools that help.
Investing Psychology Chapter 6 Part 2: Cognitive Repairs and Good Enough Decisions
We continue with Chapter 6 of Tim Richards’ Investing Psychology. In Part 1, we covered the early debiasing strategies. Now we get into the harder stuff: why we can’t let go, why we fall in love with stocks, and whether “good enough” is actually good enough.
Investing Psychology Chapter 7: The Good Enough Investing Framework
Previous: Chapter 6 Part 2
After six chapters of bad news about our brains, Chapter 7 finally gives us something we can actually use. Richards calls it “Good Enough Investing.” Not perfect investing. Not beat-the-market-every-year investing. Just good enough.
Investing Psychology Chapter 8: 10 Money Myths That Are Costing You
Chapter 8 of Investing Psychology is where Tim Richards takes everything from the book and turns it into a myth-busting session. Ten myths. All of them things most people believe. All of them wrong. Or at least, way more complicated than we think.
Investing Psychology Chapter 9: The Final Roundup and Key Lessons
We made it. Chapter 9 is the final content chapter of Tim Richards’ “Investing Psychology.” And it’s not really about new ideas. It’s a wrap-up. A summary. A last attempt to remind you what you should have learned, and why most of us will still ignore it.
Investing Psychology: Final Thoughts on Tim Richards and Behavioral Finance
So we made it. 9 chapters, 17 posts, one brain that’s a little more aware of its own tricks.
This was “Investing Psychology: The Effects of Behavioral Finance on Investment Choice and Bias” by Tim Richards (ISBN: 978-1-118-72219-0, Wiley 2014). And it was worth every page.
