Should I read The Intelligent Investor or The Psychology of Money first?
In one paragraph
Read The Psychology of Money first. Housel's 20 essays inoculate you against the emotional mistakes that destroy returns, so by the time you tackle Graham's analytical framework in The Intelligent Investor, you actually have the discipline to use it.
What this actually means
The order matters more than people admit. Graham's book is denser, longer (640 pages in the 2003 edition), and written in a 1949 voice that takes some adjustment. Open with it cold and most readers stall by chapter 4.
Psychology of Money is the opposite — 20 short essays, 250 pages, plain English. It teaches you what wrecks returns (panic-selling, lifestyle creep, social comparison) BEFORE you have money in the market to wreck.
Then go to Graham. The 2003 Jason Zweig commentary edition is the one to buy — Zweig's modern footnotes after every chapter translate Graham's 1949 examples into post-dotcom, post-2008 reality. The two ideas that earn the book: 'margin of safety' (only buy when price is well below intrinsic value) and 'Mr. Market' (the market is a manic-depressive business partner you can ignore, not a verdict on you).
Skip the order trap of 'read the classic first because it's the classic.' Graham himself would tell you to fix your behavior before your stock picks.
