This is true, it turns out:
From Grok AI:
A&W Restaurants launched a “Third Pounder” (1/3-pound patty) in the 1980s under owner A. Alfred Taubman to compete directly with McDonald’s Quarter Pounder (1/4-pound patty). It offered more beef for the same or lower price, and blind taste tests showed customers preferred it.
However, sales flopped. Focus groups revealed a significant portion of customers (often cited as around half or a majority) mistakenly believed 1/3 pound was smaller than 1/4 pound—likely because they compared the denominators (thinking the bigger number “4” meant more meat) rather than understanding fractions properly. They questioned why they should pay the same for what they perceived as less meat.
According to Snopes, this is documented in:
- A&W’s own historical account and Taubman’s book Threshold Resistance.
- Wikipedia’s entry on the third-pound burger, citing the marketing campaign “Third is the Word.”
- Fact-checks from Snopes and other outlets, which confirm the consumer misunderstanding via focus group results.
It’s become a classic case study in marketing, consumer behavior, and innumeracy. A&W has even leaned into the story humorously in later promotions (e.g., a “3/9 lb.” burger campaign).
