- "just a theory"
Why do scientists refer to evolution as a theory which leads to the argument that evolution is "just a theory"? Why don't they use a less confusing word?
And I would add to that ... almost always someone who acts like that does NOT want to be educated, so it's pointless to even have a discussion with them.People who say that something is "just a theory" in a pejorative way are simply scientifically ignorant.
I respectfully yet emphatically disagree with her emphasis. I see her recommendation as a plea to reduce scientific "fact" (what is that?) to a dogma that can be easilly swallowed. This approach is intrinsically anti-scientific and therefore eventually counterproductive and in fact dangerous.It extends into a lot of other words like belief, coincidence. Helen Quinn takes a very different tack from @hutchphd - she claims we know better and should find ways to communicate

Newton's Law of Gravity is a different story: It's a mathematical formula, that can be observed, measured, quantified, verified, and validated within its limits. So the term "law" is somewhat appropriate. This isn't just about its age... ...many newer phenomena still get the law treatment. But like Newton's law, these only pertains to one small aspect, and can be quantitatively verified and validated. Like Avogadro's law, the Boltzmann law, Hagen-Poiseulle-Law etc. etc.To add to what @hutchphd said, back in Newton's day science discoveries were considered more concrete and unlikely to change. So Newton's LAW of Gravity would today be called Newton's Theory of Gravity, [...}.
Richard Dawkins dedicated the first chapter to this problem in his book 'the greatest show on earth.'Summary: "just a theory"

Saying "evolution is just a theory" is a straw man fallacy, where the reasoning is a fallacy of relevance: it fails to address the proposition in question by misrepresenting the opposing position.https://en.wiktionary.org/wiki/theory said:Noun
theory (countable and uncountable, plural theories)
- A description of an event or system that is considered to be accurate.
- (sciences) A coherent statement or set of ideas that explains observed facts or phenomena and correctly predicts new facts or phenomena not previously observed, or which sets out the laws and principles of something known or observed; a hypothesis confirmed by observation, experiment etc. [from 17th c.]
- (uncountable) The underlying principles or methods of a given technical skill, art etc., as opposed to its practice. [from 17th c.]
- (mathematics) A field of study attempting to exhaustively describe a particular class of constructs. [from 18th c.] Knot theory classifies the mappings of a circle into 3-space.
- A hypothesis or conjecture. [from 18th c.]
- (countable, logic) A set of axioms together with all statements derivable from them; or, a set of statements which are deductively closed. Equivalently, a formal language plus a set of axioms (from which can then be derived theorems). The statements may be required to all be bound (i.e., to have no free variables). A theory is consistent if it has a model.
- (obsolete) Mental conception; reflection, consideration. [16th-18th c.]
Usage notes
In scientific discourse, the sense “unproven conjecture” is discouraged (with hypothesis or conjecture preferred), due to unintentional ambiguity and intentional equivocation with the sense “well-developed statement or structure”.
A truly terrifying piece of work, and a nice video. Makes me want to wear my facemask to bed! Show it often, lest we get too fat and happy.here's one pretty awesome for-show-experiment demonstrating and illustrating the concept of evolution:

I seem to recall the convention that historically at least, laws were called "laws" because they are cannot be disproved at such because they are are definitions (e.g. Newton's laws of motion) or are a "fitted description" based on empirical data (e.g. Hooke's law). Right?So Newton's LAW of Gravity would today be called Newton's Theory of Gravity
This is not as I understand it.So Newton's LAW of Gravity would today be called Newton's Theory of Gravity,
Einstein's GR is a theory because it is an attempt to model how things happen. It could always be replaced with a newer model.just as the more recent, and more accurate theory is called Einstein's Theory of Relativity.
Somehow, I found all the logical and meaningful explanations for that kind of backward-thought and a bit forced, also: too complex...."just a theory"...
Sorry, are you referring to Jupiter60's post?...which is only somewhat correct - evolution theory after all implies and includes how life evolved from the humble beginnings,
This meaning depends crucially upon exact definition of "life" vs "non-life" so I declare it unconditionally true. If we really want to try to define "what is life" may I suggest a dedicated thread. I care not to!"[Darwinian evolution] refers only to how life changes over time, not how life originated, not how the Earth originated, and not how the universe originated."
I am not convinced it does.This meaning depends crucially upon exact definition of "life" vs "non-life"
It seems to me that's exactly what you're requiring. Nonetheless, I still don't agree it's necessary.If we really want to try to define "what is life" may I suggest a dedicated thread. I care not to!
It could be that by chance evolution didn't happen but there were just some other animals with similar bones and organs. I mean, it's possible, but highly unlikely.Summary: "just a theory"
Why do scientists refer to evolution as a theory which leads to the argument that evolution is "just a theory"? Why don't they use a less confusing word?
There is more than just the structure (I would also include molecular biology in here) of animals (as well as plants, fungi, and everything else living) supporting the theory of evolution.It could be that by chance evolution didn't happen but there were just some other animals with similar bones and organs. I mean, it's possible, but highly unlikely.
Why don't they use a less confusing word?
I would actually agree that the term is problematic, it's too broad and over inclusive.
Well, yes, I think you're right, but we seem to have forgotten the value people put onto their beliefs, their self-esteem and their self-interest.Like so many things, scientists - the guys in the trenches - have no problem with the term. It's armchair pop-sci buffs who only read bestsellers who find it confusing.
The problem really comes down to the fact that a lot of people think science is somehow simpler / more approachable / more "common sense" than other disciplines and therefore they can weigh in with impunity.
Joe Everyman would not doubt that corporate forensic accounting is a skilled discipline and that it would take him years to learn its in and outs before being able to challenge a corporate forensic accountant.
Joe Everyman would not doubt that non-Euclidean math is a skilled discipline and that it would take him years to learn its in and outs before being able to challenge a mathematician.
Joe Everyman would not doubt that civil engineering is a skilled discipline and that it would take him years to learn its in and outs before being able to challenge a civil engineer.
But science? Well, Joe Everyman can just use his "common sense" to doubt any scientist's years of discipline.
The question was more the issue with the word "theory."It could be that by chance evolution didn't happen but there were just some other animals with similar bones and organs. I mean, it's possible, but highly unlikely.
I disagree, debate does not work unfortunately. Did you speak to any antivaxers during Covid? Flat earthers or YECs ever? Different motivations for what they believe but the absolute last thing certain groups are interested in is facts that counter their beliefs.I would actually agree that the term is problematic, it's too broad and over inclusive. If we consider evolution as denoting that change occurs over time, then It's pretty clear that evolution is a fact. However, most people use the term in biology to describe an explanatory framework which helps to explain how and why such changes occur. Used in this way, evolution describes a whole range of ideas with each one having different levels of supporting evidence, and work continues in order to refine our understanding.
I think even in physics, there can be similar problems, gravity is clearly a fact but science is more than just a collection of facts, the aim is usually to understand and use this understanding, to predict future outcomes. I suspect that for most people, its the accuracy and utility of these predictions that give the various areas of science their credibility. It has become popular for many people who claim to support science to attack those that challenge the scientific consensus, often when their isn't one.
I'm not really convinced there are large numbers of people who can be described as science deniers, people are avid consumers of the products of science and are often very interested. There are however lots of people who don't like being described as stupid or deniers when they question things, something which used to be considered a hallmark of good science. We also fail to consider the huge social value associated with belonging to large powerful, groups with shared beliefs, this has been a continuing issue in discussions of evolution.
I think that the debates around evolution, provide a really good example of some of the many problems of science in our current culture. Within the loose framework of theories, there are some with the predictive validity of haruspicy, which is fine, (well, not for the animal of course), it encourages debate. It is in fact the lack of debate that leads to these being used to discredit the whole evolutionary framework, it's hard to get good evidence for some idea's, we need to bring back critical appraisal.
I will now get back to proving my own theory that things don't fall down because of gravity, its because the Earth sucks. :)
And, being a lay-person, you could certainly ask questions that will help clarify.Then I thought about dealing with an expert in accounting that had control over my salary and who had made what I considered to be a mistake. I would be knocking on his door within minutes, I would want an explanation...
Arguments from ignorance/incredulity are not the best and the hardest to counter without being insulting.And, being a lay-person, you could certainly ask questions that will help clarify.
But you would be out-of-line to say
"Well that just doesn't make sense to me. Personally, I think finances should work like X."

"This industry word you use here is not one I understand well. Your discipline should change the word so that I feel more comfortable."
