8. THE QUADRATIC INFLUENCE SYSTEM System Postulates I:
Each behavioral choice is influenced by a complex system of factors
All behavior choices are influenced by GENETIC and ENVIRONMENTAL factors
Both genetic and environmental factors have two “streams of influence”
Genetic streams of influence are BIOLOGICAL and PSYCHOLOGICAL
Environmental streams of influence are SOCIAL and CULTURAL

9. THE QUADRATIC INFLUENCE SYSTEM System Postulates II:
All four (quadratic) streams of influence each have two substreams (making 8 altogether):
4 informative/cognitive/thoughts substreams
4 control/affective/feelings substreams
All (sub)streams of influence flow from causes most distant (ultimate and distal) to causes closest to (proximal to) the behavior of interest -- a cascade of multiple and interacting influences
Proximal causes predict most behavior
Distal and ultimate causes help explain it

10. THE QUADRATIC INFLUENCE SYSTEM System Postulates III:
Most influences can have positive or negative values;
The more positive influences there are, the more likely is positive behavior
The more negative influences there are, the more likely is negative behavior
The most proximal control/affect factors have values (probabilities) that range from zero to one

11. THE QUADRATIC INFLUENCE SYSTEM System Postulates IV:
Once a behavior occurs, the resulting reactions/experiences (thoughts and feelings) feed back to change the original causes
Feedback changes the likelihood of engaging in the same or a similar behavior in the future
Thus, causes and effects continuous cycle:
with each behavior changing the causes, and
the changed causes leading to the same, similar or different behavior over time

12. THE QUADRATIC INFLUENCE SYSTEM System Postulates V:
The reactions to certain behaviors feed back to influence the causes of related behaviors
e.g., smoking and other drug use
Related behaviors have similar causes, with the more distal causes being the most similar
Less related behaviors (e.g., smoking and skiing) have fewer causes in common
Even related behaviors have some differences in proximal causes
