Firstly academia looks for knowledge, not truths. Whether knowledge is truth is most certainly eminently debatable.
Secondly, all you have mentioned do absolutely appear in academia, but not on 'conspiracy sites'. You are looking in the wrong places.
Third, allow me to say that my wife is a Dr of Psychology, daughter a Dr of Sociology and son a Dr of Mathematical Physics. Research is something my family understands, it it fair to say.
But this isn't as weird as it looks like if one understand "Academic Science" isn't about finding any truths
Plainly a ludicrous and obviously an incorrect statement. The world that you inhabit is the creation of academic people. It is a statement made because you have some 'pet' interests and like a good conspiracy theory.
It is also a statement which shows you plainly have no idea how academia works .... In essence one requires a research subject that will pass the Ethics Committee that the individual academic is beholden to.
Then to write that research up into an accepted publishable form, one must not only discuss ones own research but compare it to the results of others, both positive and negative with regard to your own conclusions. This is to ensure basic probity and ensure that the results are valid in the round.
Therefore, if one Dr of medieval history believes that some S American frogs are the direct off spring of the Lizard people .... Whilst that 'research' can be published in the scandal sheets and on some internet conspiracy site ... It will not gain publishing in any academic journal. There is simply not enough ethical research, positive or negative - Theories MUST
be tested before acceptance in academic circles.
People such as yourself further need to grasp that the academic community only since around the start of the 1970's, grew a conscience. Only then did academia started to feel that other humans/life forms had an actual value. Go and look at some of the experiments say psychologists did in the 1950's & 1960's .... Psychological abuse of animals, children and adults that is frankly horrific
If one looks at the history of modern economics or psychology or sociology to name but three these areas of abuse stand out.
It is without doubt that the Anti-Semitism of the 3rd Reich was actively turned into all the horrors of the holocaust by economists and some social scientists of the day
. In other words whilst the NS hierarchy were undoubtedly hell bent on 'Getting rid of Jews'
for a decade that meant they kept trying to send them elsewhere and 'elsewhere' such as the UK & USA refused to take but a handful even when being bribed with money by Germany.
But at the Wannsee conference in 1942 with Heydrich & Eichmann in charge, it was the input of reports by leading German academics which made the pragmatic and fiscal case for annihilating the Jewish peoples and other 'ethnics' under the control of the 3rd Reich.
So in essence, when one or two 'scientists' say 'UFO's and the Lizard men are real!" ... Or "The Pyramids are electrical charging stations and steering guidance transmitters for UFO's" they do not get main stream acceptance in the academic community because two or even ten people do not make academic evidence a reality.
If it helps you, I absolutely 100% believe that alien life exists and IMO (i.e IMO) we, our species, we are the alien life form. If there is a God, then it is mathematics ..... But I am truly not convinced about the Lizard people though I am willing to accept Silica life forms exist.
Try reading some actual academic books, not perusing the internet sites telling you what you want to hear and feeding your personal paranoia brought on by your life impotence.
Please be aware I do not read replies. Certainly there is nothing either yourself or any others have posted which requires a debate.
