Am I resistant to advertisements, or is it all mirage?

I saw a post about how nerds are resistant to advertising, which is bs imo considering how obsessed many nerds to products. But then, I do not seem to get affected - I usually do not desire to buy a product, and only seek out what to buy when needed.

That is, I feel like adverts do not work on me. Is this an illusion? Or maybe, is it that many adverts are made to appeal to neurotypicals?
