AskScience AMA Series: I'm Lisa Fazio, a psychology professor who studies why people believe misinformation and how to correct it, AMA!

Posted: 14 Jul 2020 04:00 AM PDT

Hi Reddit! I'm Dr. Lisa Fazio and I'm an Assistant Professor of Psychology at Vanderbilt University in Nashville, TN. My research focuses on how people learn correct and incorrect information from the world around them and how to correct errors in people's knowledge. I'm particularly interested in human memory and the cognitive processes underlying learning.

In my Building Knowledge lab we study -

Why it's hard for us to notice errors in what we read:

The effect of repetition on belief:

And ways to help reduce the spread of misinformation:

I'll be joining at 2pm CT (3 PM ET, 19 UT). Ask me anything!

Do other cold/flu viruses cause permanent organ damage like COVID-19 does?

Posted: 13 Jul 2020 07:28 PM PDT

With COVID-19, permanent damage is almost a given. How does the lasting damage compare to common widespread seasonal illnesses?

Why is the core body temperature of humans seemingly so consistent, when we vary so much in other characteristics?

Posted: 13 Jul 2020 07:11 PM PDT

To expand on the title, I'm asking why ideal core body temperature is the seemingly the same for everyone, regardless of age, sex, size, etc etc.

With the threat of the Thwaites Glacier breaking off into the ocean, what would that look like to coastal cities?

Posted: 14 Jul 2020 05:05 AM PDT

Experts say the displacement of just the glacier would raise oceans .5 meters. Subsequent ice loss following could be up to 2 or even 3m of sea level rise. What would a .5 meter (or 2-3m) look like on coastal cities? Jus the beaches are gone or like 3 miles inland are under that much water

Of Sea Level - Is there a highest and lowest sea area on earth?

Posted: 14 Jul 2020 06:16 AM PDT

From a quick glance in wikipedia, I just learned that sea level is actually an average surface level of earth's bodies of water.

So I'm wondering if we know of certain seas or areas where it's particularly high or low? Perhaps on the poles or equator? Maybe a particular time of the year and with the right tides?

Are plate tectonics just a theory?

Posted: 14 Jul 2020 07:00 AM PDT

I just heard plate tectonics referred to as a theory.

I always thought of it as something that was absolutely true & that earth's continents were definitely different billions of years ago (even though the exact shapes of those continents wouldn't be exact).

Why are viruses that result in a global pandemic so rare?

Posted: 13 Jul 2020 08:46 PM PDT

I might be misunderstanding how difficult it is to actually have a virus reach humans, but shouldn't pandemics happen more often given possible poor hygiene anywhere in the world? Doesn't it just take one person out of 8 billion to be incautious and start an outbreak?

Can a comet become a moon?

Posted: 13 Jul 2020 04:57 PM PDT

I know that a lot of small moons in the solar system are thought to be captured asteroids. Can a comet be captured by a planet in a similar fashion and become a moon of said planet? If so, would it still have a tail?

Why do we call things theories even after they've been proven?

Posted: 13 Jul 2020 01:05 PM PDT

I was talking to a friend about evolution and he said the inevitable "it's just a theory". To which I said "yes it is just like relativity is also a theory but has been proven". Then he asked me why it's called a theory and not a law. To which I said "I actually dont know". Let me find out for you. So why dont we call proven scientific theories laws?

In comparison to fossil fuels, how much does the body heat of all the humans on Earth affect the global temperature?

Posted: 13 Jul 2020 02:24 PM PDT

If it's not a significant amount right now, will ever become a problem?

How does moisture affect the molecular structure of plastics like Nylon and PET specifically?

Posted: 13 Jul 2020 01:00 PM PDT

I own a 3D printer, and have to keep my filament dry in order to print objects more successfully. "Wet" filament (filament that has absorbed a lot of moisture) tends to be more brittle in my experience, and dry filament seems to have more flexibility. I looked into why this was the case, and could only find answers akin to "It affects the molecular structure of the plastic, changing its properties." This isn't enough of an answer for me. I was hypothesizing that it is potentially similar to carbon in steel, where the carbon sits inside the iron's molecular structure and makes the crystals more rigid. More carbon = more rigid and brittle, whereas less carbon leads to a softer steel. Is it a similar process in plastic, or is there something else at play here? I appreciate any help with this issue!

Why do some (?) nebulas conform to turbulent flow if their particles are few and far apart?

Why can't we predict with reasonable certainty the stability of theoretical elements?

Posted: 13 Jul 2020 09:04 AM PDT

From what I see, there's still a degree of uncertainty surrounding the proposed stability within the island of stability. Redditors on this sub don't seem to act with the kind of certainty you'd expect scientists to have protracted from what we already know about the components of atoms and the forces acting on them, at least it doesn't seem so to the layman like me.

Is it a matter of "good-taste" and etiquette that scientists don't disregard the IoS, or is it the case that there are factors (like sub-atomic particles and forces) acting on atoms which we haven't distinguished yet - or perhaps factors of uncertainty that I'm not aware of?

Why are FPGA’s less efficient than ASICs?

Posted: 13 Jul 2020 07:18 PM PDT

Like the title, is it because they have moving parts? And do the parts move electromagnetically?
