The Pavlovian myth: relevance beats emotion in ads

For most of the last century, advertisers have chased one idea: if you pair a product with a feeling often enough, the feeling rubs off. It is a seductive theory, borrowed from Pavlov’s lab, and it shaped everything from jingles to reality TV. The uncomfortable question, which researchers are finally in a position to test, is whether any of that emotional conditioning actually sells.

From Pavlov’s dogs to Little Albert

The story starts with J.B. Watson. After leaving academia, Watson took classical conditioning – Pavlov’s discovery that dogs could be trained to salivate at a bell – into advertising. His most infamous demonstration was “Little Albert,” an infant shown harmless stuffed toys just before a jarringly loud sound. Within a short time, the child cried at the sight of the toys alone.

The logic for marketers was seductive: the product is the bell, and the response is whatever warm, triumphant or thrilling feeling you can attach to it. Sports cars got paired with sex appeal. Detergent ads turned dirt into a monster to be conquered. In one ethically dubious study, researchers even conditioned young men to respond to black fur-lined boots after pairing them repeatedly with nude photographs.

Conditioning works, in other words. The open question is whether it works for sales.

Television: the perfect conditioning machine

TV looked like the ultimate vehicle. A captive audience, repeated exposure, catchy jingles that stick in children’s heads for life. Cereal mascots became so effective that Chile banned cartoon emblems on sugary breakfast products over health concerns. Soap operas earned their name because they existed to sell soap to daytime viewers.

But the golden age faded. Streaming splintered the audience, and the only live events where people still tolerate ads are major sports. Broadcasters pivoted to reality TV, where production is cheaper and products can sit quietly on the set – or on the stars.

The internet changed the question

The internet did not just change where ads run; it made them testable. Platforms like Facebook and Google built empires on the opposite of emotional conditioning: targeting people who already show interest. The holy grail is not capturing a captive audience but reaching an interested one.

A revealing experiment came from Yelp, where researchers ran ads for local businesses and then pulled them. Traffic to those businesses’ sites rose while the ads ran and fell once they stopped. The ads that worked hardest, though, were not the most emotionally powerful. They were the ones most relevant and useful to the people seeing them.

The implications for brand strategy are worth taking seriously:

• Emotional pairing can create feelings, but feelings are not purchases.
• Search and interest signals outperform broad emotional appeals in measurable tests.
• Advertising’s long-term role may be brand defence – keeping your brand visible so a rival doesn’t grow – rather than instant conversion.
• The most effective ad in the Yelp study was the one that helped the viewer, not the one that entertained them.

What this means for marketers

None of this means creative brand work is dead. It means the load-bearing part of performance advertising is usefulness, not manipulation. The review evidence suggests advertising produces modest sales increases at best. But ads still earn their keep by strengthening the brand over the long term – what one brand does today stops a competitor from doing it tomorrow.

Watson gave advertising a compelling but incomplete model. People are not salivating dogs. They are busy, distracted and selective. The ads that win are the ones that show up for someone already looking, with an answer that is genuinely useful.
