I am a pretty funny guy. When I notice a lot of psychology in a product and I "fall for it" then I feel intellectually inferior HAHA.
Yeah and they have so many "influencers" in the social media spreading the message that this and that is cool. Hydro flasks? Fox backpack? Starbucks? Uggs(sp?) And whatever else it is that teenage to young adults have to adhere to "style" to be in the in-crowd... It's all perpetuated by the media, and gotta buy diamonds on Valentine's day. Just one of the most expensive precious metals that we have... I wonder whose idea that was? Sure as hell wasn't no middle American.
Can you imagine how much a diamond company pays Hollywood to make diamonds appear in special moments in their shows and movies?
This is know as social proof. If you're not familiar with that term, maybe "me too" or "FOMO" is a better one. Amazon posotove reviews of products, which I'n fact I rely upon quite often whether right or wrong. It shows up here: we are more likely to believe/follow those how have a high post count over those that do not.
I am not advocating that this is an incorrect course of action. I'm simply stating that you are being influenced and you should try and understand when and how you are being influenced.
It's currently manifesting itself in the news media organizations and also the scientific community. However, these are topics of debate for other places and other times.
