According to a GfK Study from April 2021, asking 1001 Germans between 18 and 74, the largest influences on purchasing decisions were: - personal recommendations from friends (35,5%) - independent comparison tests (30,5%) - amazon reviews (23,2%) - media reports (13,7%) - corporate information, including advertising (10,0%)
Many of those can include advertising, such as Amazon placement and reviews, media reports (many PR firms exist to push your product onto media outlets), personal recommendations, and even independent comparison tests (people see an ad, and research it more thoroughly including seeing how it fares on comparison tests, and perhaps tell their friends too). I am not saying that the tests themselves are not independent,…

Half of that is fraud, the other half is at least unethical. Reviews may only be the personal opinion of people who provably purchased the product. False reviews are fraud and explicitly a criminal act. Placing ads in media without explicitly marking it clearly and obviously an ad, so-called “native advertising”, is explicitly a criminal act.
> the prevalence of advertising is such that you cannot disentangle its influence from every other.
My original argument was that advertising isn't necessary. I think after this discussion it's become obvious that there are many other working and prevalent ways to discover products.
In fact, all advertising does is distort and corrupt those existing methods, trying to get me to spend more money than necessary on a worse product. Every cent spent on advertising could've been spent on improving the product instead.
