Your poem discussion example also illustrates why ChatGPT isn't a good source of answers and information, though!

Chocolate in Harry Potter is used to help people recover from the effects of Dementors. But I'm almost entirely certain that the books never mention anything called "the screechings" (whether cured with chocolate or not), and a variety of Google searches returning nothing backs me up on that. (Harry Potter fans usually have very thorough web resources that I'd expect to list things like this.) And Ron never sees Voldemort in Goblet of Fire.

The problem with this sort of tech is that there is absolutely no way to distinguish when it's retrieving solid, reliable information and when it's literally making up something that sounds plausible. I ran into the exact same thing earlier today when asking it to explain some physics concepts in entertaining ways. Everything was great for a while, and then suddenly there's some absolutely BS step that isn't remotely correct, and then it goes on with a pretty solid explanation. As a physics professor, I know which is which. But if I didn't already know the answer, I could very easily be badly misled.



> As Ron's gilly-weed addiction grew, he found himself needing more and more of the substance to feel its effects. However, the gilly-weed had a strange and unexpected side effect - it gave Ron gills and the ability to breathe underwater. At first, this seemed like a blessing, as Ron was able to explore the depths of the ocean in a way that no other wizard could. But as his addiction worsened, Ron became unable to breathe outside of water, even when he wasn't under the influence of gilly-weed. He was forced to spend all of his time in the water, barely coming up for air. His skin turned pale and gaunt, and he became unrecognizable to his loved ones. In a desperate attempt to save him, Harry and Hermione staged an intervention, but it ended in tragedy when Ron suffered a fatal overdose of gilly-weed. His untimely death sent shockwaves through the wizarding world, and served as a cautionary tale about the dangers of addiction.


I'll admit in advance that this physics failure came up in a particularly silly prompt. Here's an excerpt from the response:

[...] Carrie: Okay, so what's the equation?

Samantha: It's pretty simple. It's just F = q * v * B * sinθ, where F is the magnetic force, q is the charge, v is the velocity, B is the magnetic field, and θ is the angle between the velocity and the magnetic field.

Charlotte: Okay, that makes sense. So we just plug in the values for the charge, velocity, and magnetic field, and we get the magnetic force.

Miranda: Right. And we can use the right-hand rule to determine the direction of the magnetic force.

Samantha: Exactly. The right-hand rule is a simple way to remember the direction of the magnetic force. You just point your thumb in the direction of the velocity, and your fingers in the direction of the magnetic field. Then, the magnetic force will be in the direction of your middle finger.

Carrie: Okay, I think I understand. So if we have a point charge moving in the positive x-direction, and a magnetic field pointing in the positive z-direction, the magnetic force will be in the positive y-direction.

Charlotte: That's right. And if we have a point charge moving in the positive y-direction, and a magnetic field pointing in the negative x-direction, the magnetic force will be in the positive z-direction.

Miranda: And if we have a point charge moving in the negative z-direction, and a magnetic field pointing in the positive y-direction, the magnetic force will be in the negative x-direction. [...]

[Samantha has absolutely no idea how to describe the Right Hand Rule, and assuming it's a positive charge, only Charlotte gets the right answer.]


It doesn't have enough "solid reliable information" about dementors in the training set.
