You won't believe the power of todays advertisment,
I have a masters degree in Economics and I've worked in Scandinavis and Germans advertisment & PR firms and I've also sat on the board of a $100m tech company.
Association theory. That's a word every billionaire knows nowadays. Im gonna make this as brief as possible
Basically: we have realized that people value COMMON and KNOWN things more than anything else. Our brains hold common and usual things on a higher level than new or weird things, because in the past everything that we saw on a daily basis wasnt really a threat to us, because if it had been a threat and a rare occurence, like a bear, we would've died.
90% of the people will pick coca cola instead of "Mike Root Beer Companys Great Cola Drink". 90% of the people will buy bitcoin rather than etheruem. You see where this is going
THE REAL POINT:
So, we realized that nothing matters other than the prevalence of a certain thing, and if 2 things were tied together: like a certain song playing every day on the radio and then appearing in iPhones advertisiment the effect would follow through onto the new subjcet.
In the past 5 years the supertonic note note of music, 2nd note of the keyboard, the note D in C major, was found to be the most "memorable" cadence in music, so everyone started hiring producers to use that harmony and then associate those same songs and melodies with advertisiments or even political ideologies
The Weeknd uses the 2nd note in always every one of his current hit songs and Taylor Swif, Ariana Grande t & Dua Lipa also use that note a LOT. You saw the artists preventing Trump from playing his songs? Those were artists that held songs with great assossiation percentages
It works for colors too. RED = EVIL, BLUE = GOOD dont ya think? Why do you think that? Avengers? Gangs? Yeah right, then you vote for democrat. And these things work on you too, because you'll go shopping and pick up some Coca cola too.
