Are sometimes referred to as core beliefs and are enduring and deeply ingrained indicators of what we each feel is good or bad, right or wrong.

The answer is Values.
Values will be perceived differently according to which social group you live in.
For example, People in estern countries tend to value the close living proximity with their parents after marriage, while people in western countries tend to value otherwise.

The attitude of feeling what is good and what is bad is attributed to values associated with the person. This value system is considered as core beliefs of people to follow that are deeply ingrained and practiced over a long period of time. These beliefs and values are a huge motivator of individual behavior.
