This document discusses old and new approaches to psychology. Old psychology focused on intellect, memory, emotions, and will, treating a person as a mechanical subsystem. However, the author argues this is a bad approach. A better approach, exemplified by Pavlov and Lorenz's work, treats a person as an ecological subsystem, considering their environment. The author proposes a new psychology should follow this ecological approach and classify problems into 12 classes based on the number of people involved and whether choice can be freely made.

2. Old psychology

3. Old psychology was built around four points
1. Intellect - how do we solve new problems?
2. Memory - what do we remember on old solutions?
3. Emotions - how we react on problems coming?
4. The will - how we make decision
a. to accept the problem
b. to reject the problem
c. to keep trying on the problem
d. to give up on the problem

4. Why I consider this approach bad?
Compare two approaches
in animals’ behaviour studies

5. Compare
Ivan Pavlov

6. Old psychology
(intellect + memory + emotions + will)
treats a person as a mechanical
subsystem of big mechanical system

7. New psychology should treat a person
as an ecological subsystem inside big
ecological system

8. Problems of new psychology
# How many people are around you Central problem of the class
1 0 Profession to choose
2 1 Love and marriage
3 2-10 Team building
4 50-100 Company to choose
5 1000-100000 Political movement to choose
6 More Confession / Country to choose
Every class of problem (1-6) has two subclasses
● you can choose freely - maximize profit
● you cannot choose freely - minimize harm
Total 12 classes

9. More models coming soon
