Emotional design principles that build trust, trigger desire, and turn features into feelings.
User behavior loops that build stickiness, deepen retention, and create emotional investments.
Psychological friction when to reduce it for conversion, and when to add it for intentionality.
Dark patterns vs. ethical persuasion the thin line between influence and manipulation.
