In which Wikipedia defines as:
"-An integrated pattern of human knowledge, belief, and behavior that depends upon the capacity for symbolic thought and social learning.
-The set of shared attitudes, values, goals, and practices that characterizes an institution, organization or group."
When considering human behavior one should consider the culture from which that person is from. As individual as humans can be, we are all shaped by our culture at some level. What one culture considers normal can be seen as abnormal in the next. In my cross cultural psychology seminar we learned that in some cultures dissociative identity disorder (what used to be referred to as multiple personalities) is seen as someone touched by the divine/gods.
And this is also fun when creating our characters, even ones that exist in the real world. It can be easy to overlook culture in our mainstream fiction characters, but it is still worth considering their culture and subculture. Then with the more speculative types of fiction we have more control over the elements of culture(s). What is normal social interactions for a culture? How does the main character fit in with these cultural norms? Having a character that doesn't quite gel with their cultural norms can be a nice way to work in some conflict.
