My consumerism seems to be restricted to a few kind of products for which I feel about for very specific reasons.
I'm still subject to influence, because I have eyes, but it's mostly negatively, advertising is a cheap trick void of information to me. I can't buy something because a handsome male pretended to use it in a video.
Even those with informations are often lying to put a spin on their product. Health products with a new molecule. Green vehicles. etc
Plus if you know a bit about production you know brands are often using the same materials with a few superficially differenciating details; so in the end.. same product.
I still have a technical mind, and it's my main mode of functionning. Influence can still be there but I'd bet 10$ it's barely significant.
I would bet the influence is not significant to you — you would get the same product for the same cost either way in most cases, but it is significant for the brand you end up arbitrarily choosing.
I simply mean that it makes no difference to you whether you buy your gas at Shell or Chevron because it costs the same and you get the same product. But it makes a difference to Shell if you buy your gas at Shell.
Since it is inconsequential to you, you don't care or notice the impact.
