Finding a new favorite celebrity feels a little bit like falling in love. Perhaps you find their smile endearing, or you relate to their sense of humor. Maybe you see things in your everyday routine that remind you of them. You feel like you know them so well. But whether it’s a star athlete or a Hollywood type, the reality is they likely have no idea who you are.

In this episode of Choiceology with Katy Milkman, we explore how we can develop deep connections with complete strangers — and how that in turn makes us feel more known.

BTS is the biggest boy band in the world but their popularity is not only thanks to their musical talents and highly choreographed performances. BTS has, like many other K-pop groups in South Korea, perfected the art of cultivating relationships with their fans. But when idols fail to meet fan expectations, there can be drastic consequences.

Hannah Sung explains what drew her to BTS and sheds light on the power of their fandom, known as ARMY.

Hannah Sung is a journalist and co-founder of the Media Girlfriends podcast company.

Crystal Tai tells the story of another K-pop idol, Lee Sungmin, who went from being one of Super Junior’s most popular members to being boycotted for the last decade, due to what is known in the industry as a “dating scandal.”

Crystal Tai is a senior managing editor at Jing Daily and author of the book Honjok.

Next, Katy speaks with Anuj Shah about research that shows even small tidbits of information about a stranger can cause people to mistakenly think that stranger knows them, and how a neighborhood policing initiative tested this hypothesis with surprising results.

You can read more in a paper he co-authored called Knowledge about others reduces one’s own sense of anonymity.

Anuj Shah is an associate professor of behavioral science at the University of Chicago Booth School of Business.
