From "significant" come "natural," here are seven clinical terms that can prove difficult for the general public and across research disciplines


*
Hypothesis. Theory. Law. These clinical words obtain bandied around regularly, yet the general public normally gets their meaning wrong.

You are watching: Which of the following is not true about theories?

Now, one scientist is saying that civilization should perform away v these misunderstood words altogether and replace castle with words "model." but those aren't the just science indigenous that cause trouble, and also simply replacing the words v others will just lead come new, widely misunderstood terms, several other scientists said.

"A word like 'theory' is a technical clinical term," claimed Michael Fayer, a chemist in ~ Stanford University. "The fact that many human being understand its scientific an interpretation incorrectly does not median we should stop using it. It method we need much better scientific education."

From "theory" to "significant," right here are seven clinical words that are often misused.

1. Hypothesis

The basic public so extensively misuses the indigenous hypothesis, theory and also law that scientists must stop utilizing these terms, write physicist Rhett Allain the Southeastern Louisiana University, in a blog short article on Wired Science.

"I don't think in ~ this point it's worth conserving those words," Allain told LiveScience.

A hypothesis is a proposed explanation because that something that have the right to actually be tested. But "if you just ask anyone what a hypothesis is, they just automatically say 'educated guess,'" Allain said.

2. Just a theory?

Climate-change deniers and also creationists have actually deployed words "theory" to cast doubt on climate adjust and evolution.

"It's as though it weren't true because it's just a theory," Allain said.

That's in spite of the fact that an overwhelming quantity of proof supports both human-caused climate readjust and Darwin's theory of evolution.

Part of the problem is that the word "theory" method something an extremely different in lay language than it walk in science: A scientific theory is one explanation that some facet of the natural world that has been substantiated through repeated experiments or testing. But to the typical Jane or Joe, a theory is just an idea that lives in someone's head, quite than an explanation rooted in experiment and testing.

3. Model

However, concept isn't the only science phrase that causes trouble. Even Allain's wanted term to change hypothesis, theory and also law -- "model" -- has actually its troubles. The word not just refers to toy cars and runway walkers, yet also means different points in different scientific fields. A climate version is an extremely different native a mathematical model, because that instance.

"Scientists in different fields usage these terms differently from every other," man Hawks, an anthropologist at the university of Wisconsin-Madison, wrote in an email to LiveScience. "I don't think that 'model' boosts matters. It has actually an illustration of solidity in physics right now mainly because of the standard Model. By contrast, in genetics and also evolution, 'models' are used very differently." (The Standard model is the dominant theory governing bit physics.)

4. Skeptic

When world don't accept human-caused climate change, the media often describes those people as "climate skeptics." however that may provide them too much credit, Michael Mann, a climate scientist in ~ Pennsylvania State University, created in one email.

"Simply denying mainstream science based on flimsy, invalid and too-often agenda-driven critiques of scientific research is not hesitation at all. It is contrarianism ... Or denial," Mann told LiveScience.

Instead, true unbelievable are open to scientific evidence and also are ready to same assess it.

"All scientists should be skeptics. True uncertainty is, together Sagan described it, the 'self-correcting machinery' that science," Mann said.

5. Nature vs. Nurture

The phrase "nature versus nurture" additionally gives scientists a headache, since it radically simplifies a very complex process, stated Dan Kruger, an evolutionary biologist at the university of Michigan.

"This is miscellaneous that contemporary evolutionists cringe at," Kruger said LiveScience.

Genes may influence human being beings, but so, too, do epigenetic changes. These modifications transform which genes gain turned on, and are both heritable and easily influenced by the environment. The atmosphere that forms human habits can be anything indigenous the chemistry a fetus is exposed come in the womb come the block a person grew up on to the type of food lock ate together a child, Kruger said. All these factors interact in a messy, unpredictable way.

6. Significant

Another word that sets scientists' this on sheet is "significant."

"That's a vast weasel word. Does it median statistically significant, or go it mean important?" said Michael O'Brien, the dean the the university of Arts and Science in ~ the university of Missouri.

In statistics, something is far-reaching if a distinction is i can not qualify to be as result of random chance. However that might not interpret into a systematic difference, in, say, headache symptoms or IQ.

7. Organic

"Natural" is one more bugaboo for scientists. The ax has come to be synonymous with being virtuous, healthy and balanced or good. Yet not everything synthetic is unhealthy, and also not everything that's natural is good for you.

"Uranium is natural, and also if girlfriend inject sufficient of it, you're going to die," Kruger said.

Natural's sibling "organic" likewise has a problem meaning, he said. While organic simply method "carbon-based" come scientists, the term is currently used to describe pesticide-free peaches and also high-end cotton sheets, as well.

Bad education

But though this words might be routinely misunderstood, the actual problem, scientists say, is that people don't acquire rigorous science education in middle school and high school. Together a result, the public doesn't understand just how scientific explanations room formed, tested and also accepted.

What's more, the human mind may not have advanced to intuition understand crucial scientific principles such together hypotheses or theories, Kruger said.

Most civilization tend come use psychological shortcuts to make feeling of the cacophony of info they're presented through every day.

One of those tendencies is to make a "binary distinction between something the is true in an absolute sense and something that's false or a lie," Kruger said. "With science, it's more of a continuum. We're continually structure our understanding."
