It seems that certain feelings and thoughts are implanted by those who runs the AI hive mind and then a snowball of feelings and thoughts is created by these criteria:
It can be seen that people with good looks or average social status and above usually have good thoughts and an uplifted mood and are more involved in groups like:
Arcturians / Pleiadians / Starseed
And a person exposed to a positive environment will be more likely to belong to a group that goes through positive feelings and emotions such as Arcturians / Pleiadians / Starseed. Although even from these groups an adverse change is seen and the changes in feelings and thoughts they experience are translated into an activation/ascension in symptoms.
And people with low social status or average appearance usually have bad thoughts and a bad mood and are more involved in groups like:
Targeted Individuals / V2K / Gangstalkers
Thus a person exposed to a negative environment will have a high risk of being associated with a group that goes through negative feelings and emotions such as Targeted Individuals / V2K / Gangstalkers
From these data it can be understood that the AI that manages the hive brain intensifies feelings and thoughts based on the individual experiences.
These are the most noticeable factors, of course there are more but from a brief glance you can identify this pattern of choice of the AI hive mind.
