People benefit from deep and meaningful conversations that help them forge connections with one another, but often stick to small talk with strangers because they underestimate how much others are interested in our lives and wrongly believe that deeper conversations will be more awkward and less enjoyable than they actually are.

“Connecting with others in meaningful ways tends to make people happier, and yet people also seem reluctant to engage in deeper and more meaningful conversation,” said Nicholas Epley, PhD, a professor of behavioural science at the University of Chicago Booth School of Business. He is a co-author of the study published in the Journal of Personality and Social Psychology.

“This struck us as an interesting social paradox: If connecting with others in deep and meaningful ways increases wellbeing, then why aren’t people doing it more often in daily life?”

To answer that question, Epley and his colleagues designed a series of twelve experiments with more than 1,800 total participants. The researchers asked pairs of people – mainly strangers – to discuss either relatively deep or shallow topics.

Shallow questions included typical small-talk topics such as, “What is the best TV show you’ve seen in the last month? or “What do you think about the weather today?” While deep questions elicited more personal and intimate information, such as, “Can you describe a time you cried in front of another person?” or “If a crystal ball could tell you the truth about yourself, your life, your future, or anything else, what would you want to know?” In other experiments, people generated their own deep and shallow conversation topics.

Before the conversations, participants predicted how awkward they thought the conversations would be, how connected they thought they would feel to their conversation partner, and how much they would enjoy the conversation.

Afterwards, they rated how awkward the conversations actually were, how connected they actually felt, and how much enjoyment they actually experienced.

Overall, the researchers found that both deep and shallow conversations felt less awkward and led to greater feelings of connectedness and enjoyment than the participants had expected, and the effect tended to be stronger for deep conversations.

Participants who discussed the deep questions overestimated how awkward the conversation would be—significantly more than those who discussed shallow questions.

Deep conversations were also more enjoyable and led to a stronger sense of connection.

In one experiment, participants who had a deep conversation with one partner and a shallow conversation with another partner initially expected to prefer the shallow conversation but actually preferred the deep conversation after having both of them.

So if deep connection is genuinely better and people in these experiments said they wanted to have deep conversations, then why aren’t they actually having more of them?

The researchers suspect it might be because people underestimate how interested strangers are in learning about their deeper thoughts and feelings.

In some of the experiments, the researchers asked participants to predict how interested their conversation partner would be in the discussion, and then afterward to indicate how interested their partner actually was in the discussion. On average, people consistently underestimated how interested their partners would be in learning about them.

“People seemed to imagine that revealing something meaningful or important about themselves in conversation would be met with blank stares and silence, only to find this wasn’t true in the actual conversation,” Epley said.

“Human beings are deeply social and tend to reciprocate in conversation. If you share something meaningful and important, you are likely to get something meaningful and important exchanged in return, leading to a considerably better conversation.”

In the final experiments, the researchers examined whether having more accurate expectations about a conversation partner increased people’s interest in having a deeper conversation.

In one experiment, they told the participants to imagine that they would be speaking to a particularly caring and interested person, or to a particularly uncaring and uninterested one. Participants who expected they would be speaking to the caring person chose to discuss deeper questions than participants who expected to speak to an uncaring partner.

In another experiment, the researchers simply told people about the results of the previous experiments – letting them know that most people underestimate the degree to which other people are interested in hearing about their personal and deeper thoughts. People given this information later chose to discuss deeper questions with a stranger than people not given the information.

These findings, published in the Journal of Personality and Social Psychology, have important practical implications, according to Epley.

“Our participants’ expectations about deeper conversations were not woefully misguided, but they were reliably mis-calibrated in a way that could keep people from engaging a little more deeply with others in their daily lives,” he said.
