Zaynab:
Alright, everyone. Get ready because today, we're taking a deep dive into something kinda unexpected.
Yassin:
Yeah. This time, we're looking at the world of chatbots.
Zaynab:
Chatbots and, Public health. Okay. Now you're talking.
Yassin:
And more specifically, can we actually use these things like chatbots?
Zaynab:
To help people make good decisions.
Yassin:
Yeah. Smarter health choices without, you know, breaking the bank. Right. Like With limited resources.
Zaynab:
Exactly. Because not everyone has, you know, tons of money or fancy developers to make these things.
Yassin:
Yeah. Exactly. And that's what's so cool about this research study we're looking at.
Zaynab:
Okay.
Yassin:
They built this chatbot. It's called Vwise.
Zaynab:
Vwise.
Yassin:
And it's designed to tackle COVID 19 vaccine misinformation.
Zaynab:
Okay.
Yassin:
And they did the whole thing super cheap.
Zaynab:
Now that's my kind of project.
Yassin:
Right.
Zaynab:
So we're talking about a world where, like, anyone could build one of these things
Yassin:
Yeah.
Zaynab:
Theoretically. Without needing, you know
Yassin:
A big tech company behind them.
Zaynab:
Exactly. So tell me a little more about this vWise thing.
Yassin:
So picture this. You're scrolling through Facebook or whatever Uh-huh. And this friendly chatbot pops up.
Zaynab:
Okay.
Yassin:
Ready to debunk all those COVID vaccine myths you've been hearing?
Zaynab:
Like, it just appears.
Yassin:
Yeah. And it's not some expensive custom built software or anything.
Zaynab:
Right.
Yassin:
They made it using everyday tools like ManyChat and Facebook Messenger.
Zaynab:
Okay. So they're meeting people where they already are.
Yassin:
Exactly.
Zaynab:
Smart. But how do you make a chatbot on Facebook Messenger, you know Yeah. Persuasive enough to actually change someone's mind?
Yassin:
Right. Because these are big decisions we're talking
Zaynab:
about. Like, vaccines are a big deal.
Yassin:
This is where it gets really interesting. They actually used a technique called motivational interviewing.
Zaynab:
Motivational interviewing.
Yassin:
Yeah. It's something doctors use to guide their patients towards, you know
Zaynab:
Healthier choices.
Yassin:
Exactly.
Zaynab:
Okay.
Yassin:
They basically gave this chatbot therapy skills.
Zaynab:
Hold on. Wait. They taught a chatbot to be a therapist.
Yassin:
Well, kind of like a motivational interviewer.
Zaynab:
Okay. Still, that's next level.
Yassin:
It's surprisingly effective.
Zaynab:
Really?
Yassin:
Instead of just, like, you know, bombarding people with facts and figures.
Zaynab:
Right. Which never works.
Yassin:
VWise was designed to, like, ask open ended questions.
Zaynab:
Uh-huh.
Yassin:
Understand people's concerns and then gently guide them towards accurate information about vaccines.
Zaynab:
So it's more like a conversation with someone who's actually listening to you
Yassin:
Exactly.
Zaynab:
Than, you know, just a robot spitting out facts.
Yassin:
Right. It's about building a rapport.
Zaynab:
Okay. That makes a lot more sense.
Yassin:
Yeah.
Zaynab:
It's gotta feel personal. Right?
Yassin:
Exactly.
Zaynab:
You know, like a lecture.
Yassin:
That's the key.
Zaynab:
Okay. So they've built this empathetic chatbot.
Yassin:
Uh-huh.
Zaynab:
But did it actually work?
Yassin:
That's the $1,000,000 question. Right?
Zaynab:
Right. Did people actually open up to this thing?
Yassin:
So they ran a pilot study.
Zaynab:
Okay.
Yassin:
33 people. 33 people?
Zaynab:
That's not a lot of people.
Yassin:
It's not a huge sample size.
Zaynab:
Right.
Yassin:
But the whole point of this, remember Yeah. Was to see if they could do something impactful
Zaynab:
Right.
Yassin:
With limited resources.
Zaynab:
Makes sense. You gotta start somewhere.
Yassin:
Exactly.
Zaynab:
Okay. So 33 people, they volunteered to chat with this, vWise. Yeah. What happened?
Yassin:
So think about it like this.
Zaynab:
Okay.
Yassin:
Not everyone who starts talking to a chatbot Right. Actually sticks around.
Zaynab:
Oh, yeah. I've abandoned plenty of chatbots in my day Exactly. When they're not helping.
Yassin:
Frustrating.
Zaynab:
Right. Worse.
Yassin:
But here's the thing. More than half the participants, 17 people
Zaynab:
17 out of 33.
Yassin:
Stuck with it Wow. All the way to the end.
Zaynab:
They actually completed the whole chat.
Yassin:
Yeah.
Zaynab:
Wow. So they were finding it useful.
Yassin:
It seems like take. Definitely more engaging than your average, like, customer service chat bot.
Zaynab:
For sure.
Yassin:
And get this.
Zaynab:
Okay.
Yassin:
Twelve people liked it so much.
Zaynab:
Twelve people?
Yassin:
They went back for a second chat.
Zaynab:
No way.
Yassin:
Yeah. They gave it glowing reviews.
Zaynab:
What? Like, what were they saying?
Yassin:
They said it was easy to use Okay. Explain things clearly.
Zaynab:
Mhmm.
Yassin:
And it had a surprisingly realistic personality.
Zaynab:
Okay. A chatbot with a personality, I'm intrigued.
Yassin:
Right.
Zaynab:
But let's be real here. Did it actually work?
Yassin:
What do you mean?
Zaynab:
Did chatting with vWise actually change anyone's mind about vaccines?
Yassin:
Okay. That's a real question, isn't it?
Zaynab:
That's the $1,000,000 question.
Yassin:
Right. Because we have to remember
Zaynab:
Yeah.
Yassin:
This chatbot wasn't some kind of super intelligent AI
Zaynab:
Right.
Yassin:
Debating the finer points of vaccine science.
Zaynab:
Right. It wasn't like a debate champion. It wasn't like a debate champion or anything.
Yassin:
Exactly. More like a friendly guide.
Zaynab:
Right.
Yassin:
But here's the thing. Even without being able to have these, like, super complex arguments Yeah. V wise still got people thinking differently.
Zaynab:
Really? Like, how
Yassin:
So some people who started the chat feeling hesitant about vaccines
Zaynab:
Mhmm.
Yassin:
Actually said things like K. This makes me feel more confident about taking the vaccine. Wow. Or it's good to be informed. Now I understand what mRNA even means.
Zaynab:
So it's like planting these seeds. Right?
Yassin:
Like, they might not be ready to go get vaccinated right that second. Right. But it's making them think about it differently.
Zaynab:
Exactly.
Yassin:
And that's a big deal.
Zaynab:
That's huge.
Yassin:
Because this study is challenging this assumption. Right? Yeah. That only these really advanced expensive AI systems can make a difference.
Zaynab:
Like, we don't need to wait for some supercomputer.
Yassin:
Exactly. Sometimes a simple well designed chatbot
Zaynab:
Especially one that's empathetic.
Yassin:
Yes. Exactly. That's key.
Zaynab:
Can make a real impact.
Yassin:
Absolutely.
Zaynab:
This is really cool. I love it.
Yassin:
It opens up so many possibilities. Right? Yeah. Imagine a world where everyone has access to these kinds of chatbots
Zaynab:
Like readily available health information
Yassin:
Whenever they need it.
Zaynab:
Without having to go, like, book a doctor's appointment.
Yassin:
Exactly. It could really change things.
Zaynab:
That's the future of public health right there.
Yassin:
It just might be.
Zaynab:
And you don't even need to be, like, a tech genius to make it happen. Right? That's the best part. This research shows that anyone can create something impactful.
Yassin:
With the right tools and a little creativity.
Zaynab:
So the next time you hear someone say that, like, tackling misinformation is just too hard Yeah. Remember ViewWise.
Yassin:
Exactly.
Zaynab:
It proves that even a simple chatbot can make a real difference.
Yassin:
A well designed one, of course.
Zaynab:
Of course.
Yassin:
But, yeah, that's the takeaway here.
Zaynab:
So maybe this deep dive will inspire someone out there listening to build the next fee wise.
Yassin:
That's what we're hoping for.
Zaynab:
What health issue were you passionate about? Could a chatbot be the answer?
Yassin:
Think about it.
Zaynab:
Until next time. Keep asking questions, keep diving deep, and keep learning.
