Science Makes Mistakes Too…

Science Makes Mistakes Too…

 

When I talk about a scientific explanation of events and cause and effect, I am sometimes told that, “Science also makes mistakes”.

True enough: Science makes mistakes.  However, it would be more accurate to say that Science makes mistakes and then, as part of the scientific process, vigorously and even viciously purges those mistakes from its system by experimentation, repetition and peer review over time.   This adversarial element of science to its own body of work is exemplified by the “null hypothesis” or, more colloquially, “What you said is wrong”.  If your hypothesis can withstand the onslaught of professionals in your field trying to shred your work and prove you wrong, then your idea/hypothesis wins provisional and temporary acceptance.   It is a brutal performance standard.

Einstein said, “No amount of experimentation can ever prove me right; a single experiment can prove me wrong”.  This is a very high bar of legitimacy to maintain and it is the reason why Science holds a respected place of authority in our society.  When Einstein published his Special Theory of Relativity in 1905, he was immediately ridiculed.  He remained a patent clerk for four more years.  Gregor Mendel, the founder of genetics, was complete ignored when he presented his work…for 40 years!  Charles Darwin was petrified about publishing his work and offending the prevailing religious/professional establishment of his day and so he waited for 23 years after his famous voyage.

Many people who question scientific findings still think their beliefs and ideas have the same weight as scientific theories.  This may be a semantic misunderstanding between the use of the term “hypothesis” (a proposed explanation with no evidence at the beginning of the scientific process) and a scientific “theory” which is usually the result of years of research, evidence, experimentation and peer review.  As an example, our personal ideas and beliefs about Evolution are hypotheses.  Darwin’s work is a scientific theory which has withstood the test of time: generations of experts trying to prove the “theory” of evolution wrong with no success.

If you Google up the ten worst mistakes of science, (http://www.sciencechannel.com/strange-science/10-science-mistakes) you get a very interesting list.  From Galen’s faulty idea of the circulatory system and Ptolemy’s earth centered solar system in the second century to the theory of the four humors and spontaneous generation and on to alchemy and astrology, it appears that Science has made some incredible mistakes.

Except that when these events took place, there was no Science as we know it today.  In the second century, Ptolemy watched a few sunsets and without any theoretical astronomy framework and only rudimentary tools, wrongly concluded that the sun revolved around the earth.  Galen was dealing with the incorrect medical framework of the Four Humors when he proposed a completely wrong idea for circulation.  To be sure, throughout history there have always been scientific individuals and in our more recent past there were local, coordinated groups of scientists.  However, Science as we know it today, as civilization’s organized, worldwide, multicultural network of research based, experimental explanations of cause and effect, did not exist until the 1870’s.  By that time, travel and communication between global research institutions allowed knowledge to be standardly measured and reliably repeated with the process of experimentation, data collection and repetition insuring that mistakes were purged from the system over time.

We, as individuals, have no such performance standard.  We consistently and continually make mistakes with no idea that we even made a mistake.  We claim to be our own expert but we are a completely biased, anecdotal story of one.   Science, over time and repetition, is a process that points the way to an ever more accurate picture of reality.  Individuals, over time, can continue to make the same mistake generation after generation after generation.  For millennia we continued to fabricate emotionally pleasing philosophical and spiritual explanations for natural events instead of adopting the very simple procedure of scientific methodology: observe, measure, propose an explanation, test it and have someone else check your work because we are all prone to mistakes.  Why was this simple approach so elusive?  Why couldn’t communities from 500, 1000 or even 2000 years ago process observations and information in a scientific manner?   Humanity needed a tool to prevent us from making these individual and then collective false associations, generation after generation.

Mathematics seems to have escaped the disuse that has plagued Science through the millennia and a comparison may suggest a reason for the reluctance to accept and use scientific methodology.  Mathematics offends no one and its logic is impossible to refute.  Science on the other hand, has an inverse relationship with one of the other pillars of our society: religion.  As Science explained more and more of the natural world, mystical/spiritual explanations were less and less necessary.  This process may have inadvertently offended many religious people and slowed the acceptance of various scientific theories.

Science is humanity’s method for not fooling itself.  It’s not an opinion or a belief.  It is not my way against your way.  Science is a tool for collecting repeatable evidence: a tool that insures that beliefs, opinions, individual false associations and prejudices are purged from our collective understanding of the natural world.  In the words of Carl Sagan:

“Science is not perfect.

It is often misused.

It’s only a tool, but it’s the best tool we have.

Self-correcting, ever-changing, applicable to everything;

With this tool, we vanquish the impossible”.

About Victor Dominocielo

I graduated from Fordham University with a Bachelor of Science degree in Experimental Psychology. After college, I worked as a social work assistant for the Visiting Nurse Service for two years in Harlem and the South Bronx. I came to California and got a BA in Physical Education, a teaching credential and a specialist credential in Adapted Physical Education. I worked in Special Education at Alpha Training Center for 10 years during which time I got credentials in Biology, History, Health Education and Severely Handicapped Education. I moved on to Devereux School for 12 years during which time I earned my MA in Education. Sixteen years ago, after my son graduated from Santa Barbara Middle School, I became the 8th grade Science teacher there and the Medical Coordinator for the school and their extensive Outdoor Education Program. While I was in NYC, I was part of the first class of EMT’s, working for 5 years at Lenox Hill Hospital on their 911 ambulance and in their emergency room. When I came to SB, I worked in the Cottage ER for a year and I volunteered on the Sheriff’s Search and Rescue Team as an EMT and Rescue Technician for 12 years. I have been an EMT, in and out of certification, for over 40 years. Along with teaching Human Biology and Health, this is another reason why I write about medical and health issues.
