Seller's description

Specifications

May include: A 28-page printable workbook titled The Decision Casebook with a dark blue cover featuring a gold icon, white text, and two interior pages displayed behind it. The text includes 15 real moments from history and thinking shortcuts.

Fifteen real decisions from history, each on one page, to sharpen how you make your own. A printable workbook you can finish in fifteen days, ten minutes at a time.

Every case puts you inside the moment: the captain gliding over New York with no engines, the radio operator on the Titanic with a queue of telegrams, the guide near the top of Everest at 2 p.m. You choose A or B and write how sure you are, before you read what happened. Then the page names the thinking shortcut at work, in plain words, and gives you one counter-move to try, with an honest grade of the evidence behind it. A "Your turn" box carries the lesson into your own week.

WHAT YOU GET (28 pages)
• How to use the casebook, and why these shortcuts are not flaws
• The 8 families of thinking shortcuts, in plain words: what we notice, the crowd and the person in charge, what comes to mind, risk and odds, now versus later, who I am, sticking with it, and the expert's mind
• 15 one-page cases: Greenland (985), the Great Fire of London (1666), Vienna's maternity wards (1847), Lincoln's sealed memo (1864), Shackleton (1909), the Titanic's radio room (1912), Dunkirk (1940), Mann Gulch (1949), the Bay of Pigs (1961), the first digital camera (1975), a Soviet missile alarm (1983), Challenger (1986), Everest (1996), the Simeulue tsunami (2004) and the Hudson River landing (2009)
• A one-page decision checklist: one question per family
• A 15-day practice plan with a notes column
• A blank page to work through a decision of your own
• Sources for every case, and the research behind each counter-move

WHO IT IS FOR
Curious adults who like history and want to think more clearly: team leads, coaches, teachers, students, and anyone facing a big choice. It also works for a book club or a team meeting: one case, ten minutes, a good argument.

FORMATS
• Two PDFs: US Letter (8.5 x 11 in) and A4. Same 28 pages.
• The cover is in color; the inside pages are light on ink.
• Print at home, or write on it in a PDF or notes app on a tablet.
