Ford's observation cuts deeper than mere laziness—he's identifying that genuine thinking requires holding multiple contradictory ideas simultaneously, tolerating uncertainty, and resisting the comfort of received opinions, which our brains actively resist. Most people mistake busyness, information consumption, or even strong opinions for actual thought, when real thinking demands the uncomfortable work of questioning your own assumptions. A manager might spend all day in meetings feeling productive while never asking whether the meetings themselves solve anything, mistaking activity for the harder work of stepping back and reconsidering the whole structure. Ford knew this because his own assembly line success came from thinking through problems systematically rather than accepting "that's how it's always been done"—and he recognized that most of his competitors lacked the patience for that kind of work.
