           Importance of Psychology
   
One question concerns the importance of psychology.  Why is the field of psychology important?   There may be at least three reasons why psychology is important.

1.  Self-Knowledge

      
Learning can be viewed as one purpose of life, and self-knowledge can be viewed as an important element of learning.  We may not be able to fully understand ourselves simply through self-reflection. We may not be able to fully understand the causes of our own behaviors.  We can gain a better understanding of who we are and the causes of our behaviors by learning about psychology findings in scholarly journals.  In psychology journals, there are many randomized experiments.  Because these randomized experiments allow us to make causal conclusions, we can gain insight into the true causes of our behaviors.   Moreover, a personality test may allow one to gain knowledge of one's personality.  This knowledge about personality may help to develop personal goals consistent with one's personality. 

2.  Learning About Others

      
In addition to learning about oneself, the field of psychology allows us to learn about others.  For example, we may gain insight into personality traits that are different from our own personality traits.
      It is important to gain an understanding of others to improve social relationships.  We may wish to build rapport and communicate more effectively.   Also, we may need to know how to be an effective manager or leader. 

3.  Solving Important Problems

       
Theories and findings in psychology may help us to solve important problems.  We may gain insight into new ways to solve important problems.  Because some studies in psychology are randomized experiments, we may be able to make causal conclusions
about whether certain strategies are likely to be effective.
