CAN EVERYTHING COMING FROM SCIENCE BE BELIEVED?

Most of what is considered to be true is evidenced by results from scientific research.  We all like to think of science as being factual, objective, and resulting from systematic examination of all possibilities.  Problems do arise when some ‘scientific facts’ contradict others, and, when common sense or practical experience tells us the supposed facts cannot be true.  This essay examines what factors can distort our usual assumption that science and research always tell us the truth; 3 different sources of falsity are noted.

Intermediates commonly cause problems by falsifying the issues! 

Most people do not read research reports by scientists, and so they look at articles and videos composed by non-scientists.  Problems regarding scientific research are frequently caused because the actual data and clear conclusions are interpreted by the non-scientist presenter; that often results in changes and additions or subtractions from what scientists actually give out.  Accurate and faithful presentation of research findings demands careful attention to details, what is not included, and what is simplified in the report; some of these presentations are good, but others are misleading or even draw unwarranted conclusions.

The public cannot readily determine whether a science report is good or bad, and does not have access to the scientists authoring the new research findings.  Hence, supposed ‘new facts from science’ are either blindly accepted or not believed on the basis of non-science factors (e.g., what person or program is giving the description).  What is needed to solve this type of problem with unintended falsification is for one of the scientists conducting the research to critically review the presentation before it is given out to the public.

When the results of industrial research are being presented in public media, a different kind of problem commonly arises.  Industrial research and development usually is targeted at some commercial product or activity; negative features or contradictory findings often are eliminated or minimized, thereby giving a one-sided view.  This can even go so far that a ‘science report’ really is an advertisement or a sales pitch that throws objectivity out the window in favor of growing sales and profits.  The best solution for this type of situation unfortunately is farfetched and unrealistic: everyone in the public is educated to have a much better understanding about scientific research, so that they can evaluate the announced claims by themselves.  Most people at present cannot do that since they received a limited education about science in schools, and are completely estranged from science and research as adults; this situation is very widespread in today’s world.

Research scientists often are used as actors in public disputes! 

Science is about finding what is the truth and asking questions about anything and everything.  Disagreements between researchers about new research findings and their meaning are a healthy part of science.  With more time and additional experimental data, disputes between scientists often are resolved.  Any remaining controversy about what is true mostly is due to the involvement of governments, politicians, regulators, and administrators. They typically inject non-science agendas into the arguments and simply are using scientists to win their political battles; (see:  “What Happens when Scientists Disagree?  Part V: Lessons to be Learned About Arguments Between Scientists” ).

A good example of how scientists are used in public disputes is found in the prolonged current controversy about “global warming” and its subordinate issue about “humans cause climate change” (see:  “What Happens when Scientists Disagree?  Part II:  Why is There Such a Long Controversy About Global Warming and Climate Change?” ).  Both sides claim to have scientific evidence and renowned experts supporting their position.  In fact, scientists have rather few disagreements about actual research results in this area; the ongoing arguments actually concern economics and politics!  Politicians, administrators, lawyers, and officials continue to hotly dispute and legislate what should be done (if anything!).  This type of public controversy often remains disputed for a long time and could even go on forever!

Some supposed factual accounts could be a gross deception! 

Most people agree that not everything heard or seen can be believed.  Nevertheless, it is especially difficult to decide what is true or false when something is presented as an official announcement by a government or an expert panel.  I will give one example here which is so extremely shocking that almost all adults do accept the ‘presented facts’ as being absolutely true.  To look at this critically, put aside your feelings of loyalty, patriotism, and pride just for a moment, so you can think critically about the possibility that U.S. astronauts never set foot on the Moon.

The best way to handle this question about the most widely known claim by the U.S. for its excellence in science and technology is to use the number one question asked by all scientists in their experimental research: what is the evidence?  Firstly, there are direct queries.  (1) Were samples brought back from the lunar surface, and what did these show?  Yes, samples of moon rocks were brought back, and, these were both similar and different from natural materials found here on Earth.  (2) Did video cameras show NASA astronauts on the surface of the Moon?  Yes, videos showing astronauts walking on some strange landscape were taken and made available for public viewing, but these also could have been recorded somewhere on Earth.  (3) Have any of the numerous NASA technicians claimed this is a big fake?  I am not aware of any such statements.

Secondly, there are quite a few indirect questions.  (1) Why has the Russian space program not duplicated the Moon visit?  The Russians claim to have measurements showing that the intensity of cosmic radiation somewhere between Earth and Moon is so very high that no human could survive such an exposure.  (2) Why have further Moon visits not been conducted by NASA?  The usual answer given is the huge funds necessary to do that were used for other projects with a higher priority.  (3) Why did one of the main Moon astronauts refuse to give any interviews for the remainder of his life?  This is explained as his personal choice (e.g., modesty); alternatively, the silent astronaut was so embarrassed by his role in this deception that he refused to ever talk about his experiences.

In this example there are alternative possible answers for all the above questions.  The available evidence is unable to prove either truthfulness or falsity, and hence is inconclusive.  It is painful for me to describe this, but I am presenting it only as a prominent example showing that it is necessary to question even what high officials proclaim as being the truth.

Concluding remarks! 

Although finding the truth is done by expert scientists conducting research investigations, this only reaches the public through a fog of opinionated distortions, selective omissions, and outright deceit.  Advertising and agenda-driven presentations often are commonly accepted as being true because the other side is not revealed.  Solving this situation requires that people need to be much more educated about scientific research, so they are better able to decide for themselves what is true and what is false.

HOW DO WE KNOW WHAT IS TRUE ?

How do many persons decide what is true?
           How do people decide what is really true ?      (http://dr-monsrs.net)

 

       Most of us believe that something is true because we are taught such at home, in school, or by some expert authority.  For science, the truth is judged mostly by evaluating the experimental evidence; the more evidence supporting an accepted viewpoint or theory, the greater is the certainty that it really is true.  Thus, scientists work to test and establish what we can regard as being true.  A truth that is bonafide will be consistent with other observations and experimental data, and enables valid predictions to be made; an apparent truth that really is false does not have these two cardinal characteristics. 

 

            History is full of examples where some very widely accepted truth, idea, or dogma was later proven to be false, either in whole or in part.  Testing hypotheses and re-examining accepted conclusions or established theories is a large part of the ongoing job of scientists.  Research scientists openly question all truths, theories, and dogmas.  Thomas Edison, the very famous inventor (see my recent post on “Inventors and Scientists”), is quoted as having often said, “I accept almost nothing dealing with electricity without thoroughly testing it first” [1].  Nevertheless, research scientists, just like all other people, must accept many provisional truths in order to be able to move forward with daily life both at home and in the laboratory; this general acceptance that yesterday continues into today and then on into tomorrow is a very strong practical necessity. 

 

There are plenty of controversies in both classical and modern science.  In biomedicine, there are long-debated opposing theories about what actually is the essential nature of cancer (i.e., neoplasia).  In chemistry, there are still-ongoing disputes about the detailed structure of water.  In physics, there are large disagreements about the existence, genesis, and properties of certain fundamental subatomic particles and forces.  These major controversies are both very important and very difficult targets for modern researchers.  There also are numerous smaller disputes and arguments being generated all the time.  Having all these controversies and disagreements in science is very good because they force research scientists to continue to explore, to think analytically about alternative explanations, to doubt and wonder “what if ?”, and, to be able to ask unconventional questions. 

 

For ordinary people (i.e., non-scientists), daily life usually goes on without encountering many changes in the accepted truths.  Nevertheless, it must be understood that what is regarded as being true today can change tomorrow as a result of new research results.  Scientists and other scholars (e.g., archeologists, economists, historians, museum directors, paleontologists, statisticians, etc.) as professional questioners of the truth, will advise us about some perceived need to modify our current beliefs as a result of new research findings.  To be certain, any new proposals, unexpected research results, and unconventional interpretations always remain doubted and debated until more extensive evidence can be piled up.  Changes in what we have long regarded as being true should not be feared, since these will increase our grasp of reality; it is ignorance and dogmas that should be feared.  The discovery of new truths by scientific research can create new concepts, new assumptions, and new insights, thereby causing progress in the extent of our knowledge and understanding.
