The bias that I bring to the field of psychology, comes from a background of working in Automated Control Systems (ACS) which is concerned with ‘inputs’ and ‘outputs’. 

Discernment: when looking at ‘outputs’ is not helpful

Many professionals focus on outputs (symptoms). Psychological help for people tends to focus on outputs (especially undesirable ones) toward making a ‘diagnosis of outputs’. Making an ‘output diagnosis’ is much easier than a discernment process of looking at both the inputs, the ‘cause and effect’ logic, and the outputs, which together determine a person’s responses to life. 

To understand people, we must first look at their inputs

All living things have God-given automatic control systems and intelligence which helped create the logic for their systems. To model the workings of a person’s control system, we must start by discovering the inputs (the life interactions, or the parenting /modeling relationships with adults) which affected the growing child to adapt to this system of inputs and outputs. This is often called ‘psychology’ to a non-systems person.
The most ignored inputs are under the category of neglect, or ‘that which didn't happen’.
