QT of: 'Marketing is just psychology applied to scale.' Reply: This is true but missing the constraint that matters most — psychology at scale only works when the channel rewards repetition. On X, repetition tanks reach. On TikTok, repetition is the strategy. Same psychology, different ceiling.

Validate + add constraint + give specific examples (X vs TikTok). The QT extends the original idea rather than reframing it. Readers learn something the original didn't tell them.
