theory:
- speculation: abstract thought or contemplation
- idea formed by speculation: an idea of or belief about something arrived at through speculation or conjecture
The definition above is the definition of theory that is in common use among most of us in the English speaking world. The key word in that definition is "speculation," so let's take a moment to define that word as well so that by the time I am done we will be perfectly clear as to what that word means and how it ties into the definition of the word theory.
speculation:
- opinion based on incomplete information: a conclusion, theory, or opinion based on incomplete facts or information
- reasoning based on incomplete information: reasoning based on incomplete facts or information
The next word we want to design is theory or "scientific theory" as it is used in science. For this next definition I have chosen to utilize a definition from a science education website called 'Live Science' I will be using the entire definition because at the same time it explains the scientific theory and differentiates the word theory as it is understood in common usage.
scientific theory:
When used in non-scientific context, the word “theory” implies that something is unproven or speculative. As used in science, however, a theory is an explanation or model based on observation, experimentation, and reasoning, especially one that has been tested and confirmed as a general principle helping to explain and predict natural phenomena.
As you can see in the diagram above and in the definition of scientific theory there is a huge difference on how scientists come up with theories and how they are interpreted. A scientific theory is an explanation of something based on observation, experimentation, and has been tested and confirmed as a general principle.
Note: Word definition were taken from Bing online and livescience.com
I agree Evolution is a fact and not a theory...now how do we convince those pesky creationists.
ReplyDeleteSame thing can be said about the word marriage and the opposition to gay marriage. Its only a word I just wish Theists would realize that.
Cognitive dissonance and confirmation bias make it impossible for theists to see the obvious. Theists love circular reasoning.
DeleteEvolution is both a Fact AND a Theory. Just because something in Science is proven it does not graduate from Theory to Fact. It still is a Theory. Evolution is *both* a Theory and a Fact. Did you see the flowchart above regarding Theories? Notice that nothing comes after Theory? That's because Theory is the pinnacle of Scientific Terms. There is no "Fact" After Theory because a Theory contains Facts.
DeleteLook at Websters Dictionary's definition of the word Theory; THEORY: the analysis of a set of facts in their relation to one another

When an observation is first proposed in Science it is called a Hypothesis. When enough information is gathered (Facts) and the Hypothesis is proven it then becomes a Theory. Thats it. Thats as far as it goes. A Theory never graduates to a Fact, A Theory contains Facts, Laws, Observations and makes Predictions. If there were a ranking of terms in Science Theory would be at the top. Even if additional information, (Facts) are gathered, a Theory still remains a Theory. Einsteins Theory of Relativity is over 100 years old and it still is and always will be a Theory. And it has been proven to be a Fact numerous times, yet it still remains a Theory. Ever heard of the Heliocentric Theory? It is still a Theory yet it has been proven that the Earth revolves around the Sun.
You've misinterpreted the purpose of this post which is to differentiate between the definition of theory in common usage and its definition as utilized in science. You've correctly stated that in science a theory contains facts. This is not the case in the way the average person uses and defines the word theory. From the same link you provided I will give you the common definition of theory: abstract thought : speculation and an unproved assumption : conjecture.
DeleteThe definition you've chosen among the list provided on Webster is more suitable and compatible with the scientific definition of theory. What you describe regarding the chart is what is known as the scientific method which is not the topic nor aim of this post. Thanks for your comments and insight.
That's actually one of my pet peeves - people saying "it's just a theory" because they don't know that in Science that word means pretty much the opposite of what the general public means when they use it.
ReplyDeleteIt's one of my pet peeves as well. Sometimes I feel like I am talking to a first grader. If you are going to attack a position at least take the time to research the opposing view before making a fool of yourself.
