Finance ✦ Penny’s Take
The Power of Habit
Charles Duhigg · 2012
82/100
👍 Worth It
Duhigg turns the science of habit formation into a genuinely gripping read, using cases like Alcoa's safety turnaround and Target's shopper data to show how the cue-routine-reward loop plays out in real life. Heads up: the Angie Bachmann chapter deals seriously with gambling addiction and financial ruin, so know that going in, but the reporting is thoughtful rather than exploitative.
✦ Penny’s Take — this is The Review Group’s own editorial assessment. Penny’s analytical review line researched this book from real sources and scored it across the lenses shown below. It’s an honest first-party read — not a page-by-page personal one. The gold ✓ Penny Tested mark is reserved for books Penny reads cover to cover herself.
⚠ Parent note — our reviewers flagged: mature theme: detailed gambling-addiction case study with family financial harm. We still scored it 82; these are context for your family, not an automatic skip.
