Personalisation and the Privacy Endgame
The productive tension
Personalisation as increased relevanceandas increased creepiness
the trade-off curve is nonlinear and marketers routinely misjudge where they are on it
The synthesis
Personalisation is neither the unambiguous good that ad-tech vendors sold for a decade nor the unambiguous evil that the privacy backlash now wants it to be. It is a nonlinear curve with a sweet spot somewhere between context-free mass messaging and surveillance-grade micro-targeting, and the sweet spot differs by category, culture, and moment. The evidence-based marketer treats personalisation as a dial, not a switch — tuning it against trust, measuring relevance alongside creepiness, and remembering that at the population level most growth still comes from reaching light and non-buyers with broadly relevant messages, not from firing perfectly calibrated offers at the already-loyal.
Learning objectives
- →Explain the personalisation paradox and Aguirre et al.'s 2015 finding that covertly collected data damages effectiveness even when the ad is more relevant
