A brief scroll through this thread proves that the world is both fascinating and frightening. After reading the uncomfortable revelations users typed out in this 'Ask Reddit' thread, those pieces of trivia are bound to keep you awake at night. And you’re definitely not the only one, as the post has amassed over 40k upvotes with over 15k people sharing their little nuggets of wisdom.

But where does this universal drive that pushes us to explore the unknown come from? It seems to draw us into the unfamiliar, urging us to venture into the shadows to uncover the dark facts we never knew about before.

Turns out, this mysterious driving force is something we’re all familiar with — it’s our curiosity. If we allow our craving to know and understand to roam freely, it can take us to exciting places. As Mario Livio, an astrophysicist and best-selling author of Why? What Makes Us Curious, explained to The World, humans are innately curious creatures. "Other animals are curious, but only humans are worried and curious about reasons and causes for things. Only humans really ask the question, 'Why?'"

According to him, this eagerness to understand is something we’re born with. "There are many studies that have shown that there is a strong genetic component to curiosity," he said.

"It is also the case that some people are more curious than others, in the same way that some people have a talent for music and others don’t or some people are smarter than others. But all people are curious, with the possible exception of people who are very deeply depressed or have certain kinds of brain damage."

There also seem to be two basic types of curiosity: perpetual and epistemic. We feel the former when we see something that surprises or puzzles us or doesn’t match up with our existing knowledge. "It is felt as a sort of uneasiness, an unpleasant situation, a bit like an itch you need to scratch," Livio explained.

The latter one, epistemic curiosity, is our love of knowledge and our desire to learn new things. "Our brain and our mind assign value to this knowledge, so this is usually experienced as a pleasurable thing, with an anticipation of reward in the form of what we learn," Livio added.

This particular drive pushes us to become rounded and well-informed citizens by striving to know more about our planet. Even if this means stumbling upon slightly disturbing truths we may immediately want to forget. Because life isn’t just about amusing tidbits of knowledge you can whip out during your weekly dinner party. It is also full of uncomfortable historical and scientific facts that allow us to build a broader perspective.

Unfortunately, our eagerness to learn and understand tends to diminish as we grow older. While we still share our love of knowledge, it’s harder for us to take risks to find that novelty. But that shouldn’t stop us from picking up a few tips and tricks on how to become better at sparking our curiosity.

To gain some insight on the topic, we reached out to Nancy K. Napier, Ph.D., a Distinguished Professor Emerita at Boise State University and author of Unfolding Curiosity: Wrinkles and Surprises from Business and Beyond. According to her, when it comes to curiosity, she’d offer the idea of "just a little".

Napier explained that previously she hadn’t realized that curiosity can be like an upside-down U-shaped curve. "We need to know just a little about something to make us curious to know more," she told Bored Panda. "If I've never heard of pro wrestling, I'd never even think to ask about it. So a bare minimum sparks curiosity."

Another thing that immediately awakens an interest is personal connection. "For me, at least, if there is a human connection, it's much easier to become curious," Napier revealed.

"A few years ago, a coach of Australian Rules Football (huh?) wrote to ask about an article on culture and American football that he'd seen with my name in it. We corresponded, we met, they invited me to do a creativity workshop, I watched the game and because I'd met some players and coaches, I was MUCH more curious," she added. "I'm not a sports fan but when I know someone who's on/in the team, that makes me curious."

Interestingly, shyness and boredom also pique our interest, the professor argued. "If I'm in some setting where I don't want people to know me OR if I'm bored, then I play a game with myself to shift the spotlight to someone else."

Napier challenges herself to see how long it takes in asking someone questions before his/her/their eyes light up and she has found what excites them. "I once talked with a super boring accountant and used this challenge — it took me about three minutes to learn he's a world-class fly fishing expert and we were off and running for 45 minutes. I learned a lot and he was thrilled to talk about that rather than having to talk business," she mentioned.
