In an experiment conducted by the Harvard Business School, the researchers found out an exploitable psychological trick.
The experiment begins when it starts raining that day. Researchers gathered data by approaching strangers and asking to borrow their phones in the first sample group. In the second sample group, they would first say "I'm sorry for the rain!", before the request.
When the researchers didn't mention the rain, they were trusted only 9% of the time. However, when the researchers apologized for the rain first, that number rose up to 400%.
There seems to be an innate trait for people to trust others who are humble and apologetic for things that are out of their control. For those people imply care.
Notice that this research was conducted by a business school?
Psychology is used by companies to take advantage of humans' natural impulses. The Customer Service Industry is one the best users of this exploit. They formulate words to touch the masses' weak points and satisfy them with the right amount of scripting.
