I understood how fortune tellers and horoscopes were worked, Did not know the term Forer effect tho :)
The one thing about the positioning of stars having an influence over moods lucky numbers things you should and should not do, would it not also be reasonable there to assume that distance proximity to a source has a bearing on the influential effect one thing can have on another. Take then into account the movement of the galaxies these stars are within. The majority of galaxy are moving away from each other with increasing and faster growing distance, that if the stars had any effect on the lives of people, the influence decreases each day as the distance grows. I say this to show there is always more then what is said to you,

When you take this to a higher level, or larger community of people. the same thing is done through media outlets. A persons line of thought can be manipulated to a degree by the information shown. Depending on the media shown, which side of a situation is pushed.
While the fortune teller and horoscope writer are wanting you to part with money, The media control is used to persuade your opinions. There is no investigative journalism done, it is democratic or republican, The truth is never told. The room for neutrality is diminished.

I may have went a bit off topic there. But! people need to think through the things they hear and read, and not accept everything at face value. Opinions are great to be expressed, unless the opinion is discussed and agreed upon on a large scale of the population, it remains opinion and not fact.

This is what I like most about Steemit, the ability for a wider range of audience to have and voice their opinion on any topic.
