Biases, recognizing them

    Just like on the ted talk about battling bad science by ben goldachre where he talks about medical journals only publishing the clinical trials that are positive in a ratio of about 36 to 4 when it should be 36 to 32 in actuality, when someone is not told all of the information they cannot make an accurate informed decision about anything.  This same thing is talked about in another way, if I was a magician and and flipped a coin 100 times yet withheld 50 flips of my choice, I could convince you I had a coin with 2 heads, this same thing applys when people withhold information from someone that they want an honest opinion from.  It requires both people to be honest with themselves and a neutral 3rd party if they were in therapy or if they wanted an objective opinion.  When you don't have all the information or someone or a group of people withhold information from you, either intentionally or unintentionally, especially when asked, and even more so when you trusted them by being honest and they cannot do the same what would this make the average person think if this happened within a family over a period of time and somehow you were still able to trust people but people kept on doing the same thing by going silent, not explaining why certain things happened or why they happened?   I avoid confrontations at all cost due to my trusting nature, but when one's own family refuses to hear you out nor give you answers that only reside with them that have led them to form negative opinions about you, and refuse to answer even the simplest questions or worse demean, belittle, or stigmatize you even thou, you have done all the research and can remember the most, were the only one to go thru something, then you slowly realize that each one of the people you had a problem with during one 6 month period of time, and you lived by these people and knew them better than other people did due to their narcissistic nature in taking any opportunity to talk about themselves or complain about other's even their own family members, and all the family and systems put in place in order to get a situation resolved have failed due to your own family believing them, using their social status to work against you, while you do the right thing based on all the available information and your own intuition or gut feeling and know certain things happened, and know other's didn't but haven't been able to rule out anything due to all the secrets or silence when something as simple as what my father should have done, would have been simply knocking on their door and asking them if they made the comment would have prevented so much emotional turmoil,  because when he laughed instead of doing what I would do in the same situation, let them know that they could slowly but sure get away with torturing you, night after night, simply because of my father laughing at someone trying to ruin my reputation, yet if it was his and his father laughed as some people continued to ruin someone's reputation, and you find out that every one of the people you thought you could trust are common ordinary narcissist's, What would you do?  Even looking back, either my father is so narcissistic and contrary and truly wanted his son dead, he should just be a man and flat out shoot me instead of continuing to torture someone by not being honest, lying, and then patronizing the one person that was victimized time after time.   Does anyone else see where there should be a law against this egregious behavior especially when you call the cops due to being physically harassed for the 2nd time and the officer writes down that you "claimed" you were assaulted when it absolutely happened.  So when my sister called the police a long time ago, why did they believe her and not put that she "claimed" we had a wrestling match where no one got hurt but when honest I told them exactly why I did what I did, which was just emotional dysregulation but and I didn't even know myself why I got mad but since my sister was ashamed of taking opiates during her son's pregnancy and having marital problems at the time, of which she was being supported by my mother, who later on when confronted with the actual police report wouldn't even admit she had made up details to a past event.  Just like I've said getting a spoiled brat, who has been turned into a narcissist over time to admit when they are wrong is like trying to catch a greased pig, while the greased pig puts you down for making a mess or belittles you.
