Groups with numbers are people of one type.
When watching examples, evaluate your intuitive impressions from their nonverbal - how generalized image from people of one type corresponds with the criterion of your "psychic comfort and friendly sympathy", rather than personal alienation.
Use examples only of other sex, >= 3 examples per type (if the quantity allows), for every example watch >= 2 clips, every clip for several minutes with good seen face. The more you'll watch, the more correct will be generalized impression from the type. Note: for types' sorting use only the criterion above, not sexual or romantic interest.
Arrange all 16 types in order corresponding to the criterion from the most to the least. Don't select groups of types - full sorting of all types is needed.
When comparing types don't think for long time, - make the choice by intuitive inspiration.
Watching and sorting of types can be done in several days, but in the last day of the final sorting you need to slightly refresh the impressions of previously watched types.
Don't open(!) the key until you'll finish the sorting of the types. Only then it's acceptable to see what types correspond to the numbers. After opening the key and until the end of the analysis, you should not rearrange the types.
