Why You Should Never Say "It's Just A Theory"

A portion of our culture distrusts the scientific method, assuming that there are transcendent truths unknowable by science. But nothing is truly out of bounds for science. If it's real, it can be studied, and tested. Perhaps the greatest misunderstanding our culture has about the scientific method involves the definition of the word "theory". A theory is not a guess, and this word does not in any way imply uncertainty about the validity of a concept or an equation. Watch this and learn more about the terms hypothesis, theory, and law.

I've had to explain what a Scientific Theory is every year for 6 years to my family over Thanksgiving dinner. The only reason I sometimes get through to them, is because they all remember learning about this in their own way during middle school. "Oh yeah, Isaak Newton, Gravity, The Scientific method. Maybe he's not lying." Now imagine the people who never hear about any of that growing up, who only know Theocracy and creations myths. It terrifies me to think of the places around the world that are in favor of this knowledge becoming lost. Sorry about the rant.

It's not so much that scientists screwed up by using the word theory, it's that people bugger up the meanings of words when they use them inappropriately. People say "I have a theory" when they mean "I have a hypothesis" - probably because "theory" is shorter and easy to say.

Whilst I understand what Professor Dave is getting at, that scientific theories can't just be ignored as they are empirical, it doesn't mean that it can't be disproven, it just means it hasn't yet been disproven. For example, we can rearrange theoretical equations to interpret different meanings but the maths can still hold up. Take the equation PE = mgh and rearrange it h = mg/PE. The first says the potential energy is the product of an objects mass, the gravitational constant and the height from the ground, where as the last says the height is the product of the mass and gravity of the object divided by it's PE. We can empirically test that this correct, but is it fair to say that give an object with mass a potential energy and it will gain height? I'm being disingenuous here, I admit, I know that there's more to what I just wrote, but I wanted to discuss how empiricism is not entirely without criticism.

Saying "it's just a theory" immediately proves the person has no understanding of scientific terminology. Why do so many people not understand that some words have different meanings in science than they do in real life? A great example is the word "weight". In science, "weight" is defined as the gravitational force acting on an object, and is measured in Newtons (N). In everyday use, "weight" is used to describe how heavy something is, and is measured in kilograms (kg). In both cases, "weight" is being used in roughly the same way, but it's use in science is much more specific, and different units are used.

My favorite fact far as this goes is that for once the Americans have something right. Stones and pounds are a measure of force, the measure of mass being slugs. It gets ugly when you try to do physics with it though, so I’ll stay metric.

"Why do so many people not understand that some words have different meanings in science than they do in real life?" Idk... probably because we use them in real life all the time assuming the meaning we learned from the people surrounding us is the true meaning, and need explanation to use the actual true meaning? It's a bit more complicated than "people are dumb"

Honestly this is one of those cases where I think the wise solution to this problem would just be to switch the definitions of theory and hypothesis, or at least use some other word for "theory." I'm sorry, you can't win. The word has been ruined by decades, if not centuries, of linguistic misuse and no amount of lecturing and "well, actually" essays will ever change that. Just call it something else. Use something from the legal world. You already have scientific "laws", which very, very few people ever argue with. Sure, there's flat Earthers and new mexico crystal magic hippies arguing against the laws of physics, but you weren't ever going to convince them, anyways. IDK, you could go full Douglas Adams and call them scientific "regulations" lmao. Or maybe a "treaty." Then when people argue against them you can say you're "sanctioning" their intelligence :D

Excellent explanation. I am seeing this late in 2021, just over 50 years after Apollo 15, when Astronaut (and Mission Commander) Dave Scott did his own version of Galileo’s experiment on the lunar surface, where he dropped a geology tool and a falcon feather (the Lunar Module was named “Falcon”). Because of the absence of an atmosphere, both hit the ground at exactly the same time, though they accelerated much more slowly in the Moon’s lower gravity field. That certainly holds the long distance record for that particular experiment, and CDR Scott gave full credit to Galileo. Apollo 15 was the first of the three “J” Missions, where science became the primary focus, with more extended time on the surface, with new EVA suits and the use of a lunar rover, allowing much more extensive EVA’s, which allowed the crew to cover more ground, and allowed viewers on Earth to see much more, as a television camera could be mounted on the rover.

The scientific method is brilliant, and while theory’s often hold far more weight than a lot of people perceive, there is also issues with having a dogmatic approach to theories (not saying this video does).

To anyone who's ever criticized Bill Nye for 'not being a scientist', make sure you watch this whole video. At no point does Dave say "to do science, you need to have Master's degrees from University." All you really need for science is an ability to observe, an ability to admit when you are wrong (and more importantly, when you DON'T KNOW), and a desire to understand the world around you. If you have those 3 things, you are a scientist. You might not be a rocket scientist, or a nuclear scientist, or a chemical scientist, but you are still a scientist.

Those that survive are then exposed to permanent assault by experimental data, leaving most of them dead an buried. The theories are the fortresses that remain afterwards, where you usually only have to do a paint job to the outside walls once your opponent runs out of ammo.

I have similar experience. I never had a clue what science really is until college. I took an intro geography class (physical geography), which was basically the same thing as geology 101. Which I took the following semester, followed by several more geology classes and other science classes. Loved it, though I couldn’t keep up once I started taking more advanced classes. I never had any interest in science prior to this because high school never taught me what science really is. To me, in high school, it was just a bunch of boring facts to memorize and regurgitate, like everything else in high school. But after being exposed to what science really is, I realized science is basically problem-solving, using the same thought processes I already used. Even though I didn’t end up going very far in science, it still made a huge impact. It bothers me how often the word science is misused in today’s world. Especially by doctors. Who all seem to believe they are scientists even though they don’t have to take science classes (and obviously don’t know what science is).
