Who Decides What Is Science?
Science, Authority and the Courage to Question
We frequently hear statements such as:
“Science has proved…”
or:
“Science does not accept…”
These statements sound final. They carry authority and appear to leave little room for further discussion.
But what exactly do we mean by science?
Science is not a person, an institution or an authority sitting somewhere and deciding what is true and what is false. Science is a method of acquiring knowledge: observing, questioning, forming hypotheses, collecting evidence, testing explanations and, perhaps most importantly, remaining prepared to revise conclusions when the evidence requires it.
The history of science is therefore not merely a history of discoveries.
It is also a history of corrections.
Accepted Knowledge Does Not Necessarily Mean Permanent Truth
Many ideas that were once accepted by respected scientific and medical authorities were subsequently modified, rejected or replaced.
This should not be regarded as a weakness of science.
It is one of its greatest strengths.
A genuine scientific approach must contain the possibility of being wrong.
Medical treatments change. Diagnostic criteria change. Psychological theories change. Diseases are reclassified. New technologies reveal phenomena that could not previously be observed. Research methods improve, and conclusions that once appeared convincing may later become questionable.
Today's scientific consensus represents the best interpretation of the available evidence at this particular point in time.
It should command respect.
But respect is not the same as unquestioning obedience.
Who Creates the Classifications?
This becomes particularly interesting when science attempts to classify human behaviour.
A virus can be examined under controlled conditions. A chemical substance can be measured. The boiling point of water does not depend upon whether the observer considers boiling desirable or undesirable.
Human behaviour is different.
Concepts such as normal, abnormal, adaptive, maladaptive, healthy and pathological inevitably involve interpretation.
Psychiatry provides a particularly interesting historical example.
The Diagnostic and Statistical Manual of Mental Disorders – the DSM, has undergone repeated revisions since its first publication in 1952. Disorders have been added, removed, divided, combined and redefined as psychiatric knowledge and concepts have developed.
One of the best-known examples is homosexuality.
Homosexuality was once classified within psychiatric diagnostic systems as a disorder. During the 1970s that classification was reconsidered and homosexuality itself was removed from the DSM.
Human sexuality did not suddenly change.
The professional interpretation of it changed.
This does not demonstrate that psychiatry is unscientific. It demonstrates something much more important: even established professional classifications are products of the knowledge, assumptions, evidence and social understanding available at a particular time.
They can, and sometimes should, be challenged.
Consensus Is Important – But It Is Not Evidence Itself
Scientific consensus has enormous value.
When many independent researchers repeatedly obtain compatible results using sound methods, confidence in a conclusion naturally increases.
But consensus and evidence are not identical.
Consensus is a conclusion drawn from evidence.
That distinction matters.
If we begin treating consensus itself as proof, science risks becoming circular:
It is true because the scientific community accepts it, and the scientific community accepts it because it is true.
The more scientific question is always:
What is the evidence upon which the conclusion is based?
That question should apply equally to ideas we accept and ideas we reject.
The Problem With the Word “Pseudoscience”
“Pseudoscience” can be a useful description when a discipline deliberately avoids testing, rejects contradictory evidence, makes claims that cannot be examined or presents beliefs as established facts.
But the word can also become a shortcut.
Once something has been labelled pseudoscience, people may feel that there is no longer any need to examine it.
The label has replaced the investigation.
That is intellectually dangerous.
Calling an idea scientific does not make it correct.
Calling an idea pseudoscientific does not, by itself, demonstrate that every observation associated with it is incorrect.
In both cases, the professional responsibility remains the same:
Examine the evidence.
And What About Graphology?
Graphology provides an interesting example precisely because its status remains controversial.
It has long professional traditions in several countries and has at different times been studied within academic environments. At the same time, mainstream contemporary psychology has been highly critical of claims that personality can reliably be predicted from handwriting.
Both facts deserve acknowledgement.
But perhaps the question has sometimes been framed too simply.
If graphology is presented as a system in which one handwriting sign automatically reveals one personality characteristic –
large writing means this;
a right slant means that;
heavy pressure means something else –
then scepticism is entirely understandable.
Human beings are not that simple.
Neither is handwriting.
Handwriting is a highly complex learned motor behaviour involving the brain, central nervous system, sensory feedback, muscular coordination and thousands upon thousands of repetitions through which the original writing model gradually becomes individualised.
The interesting question is therefore not:
“Does this handwriting sign equal this personality trait?”
It is:
“What does the complete pattern of movement, form, rhythm, organisation and variation tell us about the way this individual performs this highly individualised behaviour?”
That is a much more sophisticated question.
It is also a much more scientific one.
Science Requires Scepticism in Both Directions
There is an irony in scientific scepticism.
We are usually encouraged to be sceptical of unconventional claims.
Quite correctly.
But genuine scepticism must operate in both directions.
We should question extraordinary claims.
We should also be willing to question the reasons those claims have been dismissed.
Otherwise scepticism itself becomes a belief system.
A scientist should be capable of saying:
“I don't know.”
That sentence does not weaken science.
It protects it.
There is an enormous difference between:
“There is insufficient evidence for me to accept this claim.”
and:
“This phenomenon does not exist.”
The first is a scientific position.
The second requires evidence of its own.
Beyond the Obvious
Perhaps the greatest danger to scientific thinking is not ignorance.
It is certainty.
The moment we become completely certain that our present explanation must be the final explanation, curiosity stops. Questions become inconvenient. Contradictory observations are dismissed rather than investigated.
Science advances because someone eventually asks:
“But what if our explanation is incomplete?”
That question has overturned accepted ideas throughout human history.
It does not mean that every alternative theory deserves acceptance. It does not mean that evidence can be replaced by intuition, belief or personal conviction.
Quite the opposite.
It means that every claim, including the claim that something is impossible, invalid or pseudoscientific, should remain open to examination according to the quality of the evidence supporting it.
Authority deserves consideration.
Consensus deserves respect.
Evidence deserves something more.
It deserves examination.
That is the difference between accepting what is obvious and asking what lies behind it.
Beyond the Obvious – where questioning is not the enemy of science, but one of its essential foundations.
