Because, Medium aside, not a lot of people spend a lot of time thinking about how they think. Most people get up, go through their day and never think about their core programming. Intelligent people too. They go through life following the blueprint given to them about how things should be. It takes a lot to paradigm shift a person like this - usually it's the death of a relative or a brush with death.

Most people will not recognise a need for change in their lives because most human beings are stubbornly resistant to the concept of change itself.

You have to change the programming not reverse engineer the problem. :o)
