Creative Effectiveness
Myth:AI-generated ads are too crude to tell you anything about the real spot.
Evidence:In a peer-reviewed proof-of-concept, AI-generated static and video pretest ads scored statistically indistinguishable from the real finished ads they were based on - recall, recognition, brand choice, brand attitude, ad liking.
One study under specific conditions; pretesting validity is not production quality. Use AI pretests to kill weak concepts early, not to ship.

Creative Effectiveness
Myth:Targeting and media buying determine campaign outcomes.
Evidence:Creative quality accounts for roughly half of advertising-driven sales variance — a larger share than any single media variable.
Creative Effectiveness
Myth:Rational product messaging drives the strongest results.
Evidence:Emotionally led campaigns produce roughly twice the long-term business effects of rational ones, and the gap widens with campaign duration.
Creative Effectiveness
Myth:Award-winning creativity is automatically more effective.
Evidence:Across nearly 600 IPA Effectiveness Award case studies (1996-2018), creatively awarded campaigns have fallen to their lowest effectiveness in 24 years of analysis and are now no more effective than non-awarded campaigns; short-termism is the main driver.
Creative Effectiveness
Myth:Creative quality alone determines effectiveness.
Evidence:Comparing 4,863 effectiveness award cases (2011-2019), the largest business effects came from 'creatively committed' campaigns: more media spend, more channels, and longer durations behind one creative platform - captured in the Creative Effectiveness Ladder.
Creative Effectiveness
Myth:Tight, information-dense ads are the efficient choice.
Evidence:Broad, character-led, 'right-brain' creative correlates with far larger long-term effects than narrow message-dense executions.
