I thought I would be able to let go of lenak?s post, but its content ignorance and take on ?narrow minded? non-believers is killing me. So here it goes.
?people have borrowed this book and everyone single one was surprised by the accuracy?
Because of selective perception and our talent for pattern recognition. In other words, people recognize the bits that seem relevant and disregard the rest, especially if they want to believe, like anyone who would read a book on their children?s star signs in the first place.
In the same book I told about earlier, Carl Sagan also tells of an experiment: ?Free horoscopes cast, just send your details? says a newspaper ad. Many people answer and get their horoscopes. After a while, they are asked if it was good for them. The vast majority said they were impressed, it was great, etc. They were all sent the same horoscope, that of a serial killer in prison with XYY syndrome.
?because I don't think we can fully understand influence the universe has on our world (physical as well as metaphysical).?
1 Our world is part of the universe
2 There is no such thing as a ?metaphysical world?
3 You would be able to understand the universe, if you read scientific books rather than numpty literature on astrological career advice for your children 
?We know that the moon physically impacts on both the planet (tides) ... due to magnetic forces and light etc?
Tides are due to moon?s gravity, you dingbat. Moon doesn?t have a rotating metal inner core like the earth so no significant magnetic field of its own. What little magnetic properties it has are due to its passing through the earth?s magnetic field.
?to discount the fact that the other planets and stars exert influence ... seems a bit, well, narrow minded?
There is no such ?fact?, except the gravitational pull that all objects exert on each other depending on their mass and distance. This pull does not determine character traits of babies at the moment of their birth and it is categorically numptastic to believe that it does.
?acupuncture ... proven to help some types of pain and nausea and while scientists generally think that it is a placebo affect?
You know that acupuncture is proven to be no better than placebo and you think that is a good thing?
Woman, is there no limit to your ignorance? This means it has no effect except in the mind of its believers. You might as well pray for the pain to go away.
?Knowledge is cyclical?
That has to be one of the top five most ridiculous statements ever on MN, and that is against some competition. Like, all we learned about the world and the universe in the past 100 years was already known? Because, what, some stargazer shaman told you so?
?There is nothing with keeping and open mind?
Just not so open that wind blows through it.
In other words, you need knowledge and understanding of what is already known before you can judge whether or not any new theory is credible or crackpot. Because you lack the basic knowledge and understanding, everything looks equally credible to you. That is not a good thing, regardless of how you kid yourself about having such an ?open mind?
