Charles Duhigg

The Power of Habit

In the prologue, Duhigg traces his interest in habits to reporting in Iraq and a conversation with an Army major near Kufa. The officer described changing crowd routines by removing food vendors. Duhigg uses that account to move from a personal habit to a question about collective behavior.

The author’s own reported origin story, in the prologue; the officer’s account is not a controlled experiment. · lines 337–370
