"When people are instructed to ask more questions," Huang writes in the study, "they are perceived as higher in responsiveness, an interpersonal construct that captures listening, understanding, validation, and care."
The second study had the same setup but asked a third person to read a transcript of the conversation and give their thoughts about the two people talking. Readers tended to find the person who answered questions more likable. “We suspect this is because people who answer lots of questions end up revealing more information about their thoughts, ideas, and perspectives,” Huang told the Huffington Post. “They seem more interesting and complete.”
The takeaway is that there's a balance to be struck of revealing a bit about yourself and also asking questions. Though, questions shouldn't be interrogative like a job interview. They should be conversational and you should ask follow-up questions.
