Personal values can be ethical, moral, ideological, social, or even aesthetic. Values are mostly transmitted through parenting, but our cultural environment also plays a role.
For instance, American parents tend to value intellectual knowledge; Swedish parents value security and happiness; and Dutch parents value independence and the ability to stick to a schedule.
There are four different personal value orientations based on our "terminal values " - our desirable states of existence, and "instrumental values" - the means by which we achieve our end goals.
Personal-competence."I value wisdom (terminal), which I believe can be achieved through independent thinking (instrumental)."
Personal-moral: "I valued true friendship (terminal), which I believe can be achieved through honesty (instrumental)."
Social-competence: "I valued equality (terminal), which I think can be achieved through ambitious work (instrumental)."
Social-moral:"I value national security (terminal), which I believe can be achieved through obedience (instrumental)."
The limits of our memory serve us well in many respects.
Limited memories are useful trade-off to allow us to function and survive. We have thousands of memories, for example, of tables. If we recall all the events related to a table, it will create mass confusion with data overload.
Flawed memories may also help us to cope with our past and navigate our future. It may give us more confidence in our past decisions or make us remember happier events.
