Just as we have studied 12 years, we know that there is something called a calculator that can do everything instead of it. There are also related softwares in psychology, but during college, you are required to learn the psychological calculation method of the whole psychological process, starting from the most basic.

And if you want to choose a major, you need to realize that what you like is different from what you study, just as liking computers is different from learning computer programming. I hope it helps you.
