Friction engineering: the practice of deliberately
Friction engineering: the practice of deliberately manipulating friction costs — adding steps to actions that damage you and removing steps from actions that serve you — so that your environment's accounting works in your favor
Why This Is a Definition
This definition precisely delineates 'friction engineering' by naming it, identifying its genus (practice manipulating friction), and specifying its differentia (adding steps to harmful behaviors, removing steps from beneficial behaviors). It clearly distinguishes it from willpower-based approaches and establishes its purpose.
