We, humans, have our preprogrammed triggers that work wonder for the market, sales and persuasion. To initiate that preprogrammed triggers we have to understand specific niche customer habits and small unnecessary details that normal people overlook(but these help in selling your ideas to people). Let me elaborate using two examples.
At first, I am selling this proposal with a reason and the human mind get satisfied if any request is followed by a reason. Whereas I am requesting without giving any reasons. So Because plays a key role. You can easily predict which one of the images will gain more sales.


"I thought expensive was good." I heard this from my disappointed friend because she tried dumplings from an expensive restaurant and it tasted horrible. It got me thinking about where is this thinking coming from and why we as a society think like this? Then I started reading Harvard social psychologist Ellen Langer experiment on this human behaviour. The "expensive=good" stereotype we have gotten inside our head from various TV programs, marketing campaigns, friends and movies. This mentality helps our mind to relive that lifestyle and thus it becomes a habit. So let's dissect this psychology and see the marketing tactics used on us by others or by our mind itself.
That's why statistically people bet on the price and make a parallel with the brand they use or want to buy. That's how persuasion works using a 70% off poster works and you don't have a clue about it. This concept is just a small part of cumulative neuromarketing used by developers, psychologists and salespeople.
"That's rude. How can you say those things to me?" This sentence brings a glimpse of sadness when said to someone. Why does this happen? It triggers our stimuli that are linked to images of experiences. In short, people knowingly or unknowingly trigger these points that are coded in our minds because of experiences and learning from our childhood. Exploiting these types of triggers similar to "Expensive is good" people sell their products. Corporations with data know customers needs, mindsets and habits. To pitch a product and gain sales they need to see the analytics of these things. That's why companies like Byjus could acquire lots of parents' trust through their sales model using analytics that targets parents' fear and acceptability in society. They exploit the power of triggers to sell their service.
