Charles Duhigg (2012)
“A Pulitzer Prize-winning reporter reveals the science of habit formation and demonstrates that by understanding the habit loop — cue, routine, reward — you can reprogram behaviors that feel automatic and unchangeable.”

13questions designed to challenge assumptions and provoke original thinking. These can't be answered from a summary — you need the actual text.
Identify a habit you want to change. Using Duhigg's framework, analyze its habit loop: What is the cue? What is the routine? What is the reward? How might you insert a different routine while keeping the same cue and reward?
Duhigg argues that habits never truly disappear — they are encoded in the basal ganglia and can be reactivated by the original cue. What implications does this have for addiction recovery, and how does it explain relapse?
Paul O'Neill transformed Alcoa by focusing on safety rather than profits. Why was this more effective than a direct focus on financial performance? What does this suggest about the relationship between narrow focus and broad results?
The Febreze case study shows that a product failed when marketed to people with odor problems (who didn't notice their own smell) and succeeded when repositioned as a cleaning-routine reward. What does this reveal about the importance of cue identification in habit-based product design?
Duhigg presents willpower as a 'muscle' that can be depleted and strengthened. The ego depletion model has faced replication challenges. Does this undermine the book's practical advice about willpower, or is the advice useful regardless of the specific mechanism?
How does social media use the habit loop to create engagement? Identify the cue, routine, and reward for a specific social media habit (checking Instagram, scrolling TikTok, refreshing Twitter). How might you change the routine while keeping the same cue and reward?
Duhigg analyzes the civil rights movement through the lens of habit science — strong ties, weak ties, and identity habits. Is this a useful analytical framework, or does it reduce a moral and political struggle to behavioral mechanics? What does the framework capture and what does it miss?
What is a keystone habit in your own life — a single habit that, if established or changed, would trigger improvements in other areas? Why do you think this particular habit has cascading effects?
Duhigg argues that AA works through habit change rather than (or in addition to) spiritual transformation. Is this analysis respectful or reductive? Can a scientific framework capture the full reality of addiction recovery?
Compare Duhigg's habit loop with B.F. Skinner's operant conditioning framework (stimulus, response, reinforcement). How are they similar? How do the neuroscience findings Duhigg cites add to or modify the behaviorist framework?
Starbucks uses the LATTE method to train employees in handling difficult interactions. What are the ethical implications of corporations engineering employee habits? Is this empowerment or manipulation?
Duhigg wrote this book in 2012. How has the science of habits evolved since then? Research James Clear's Atomic Habits (2018) or BJ Fogg's Tiny Habits (2019) and identify what they add to or modify in Duhigg's framework.
Eugene Pauly could form new habits without forming new memories. What does this imply about the relationship between consciousness and behavior? How much of what we do requires awareness?
