“The preliminary results of our study suggest that people are more likely to disclose sensitive information via text messages than in voice interviews,” says Fred Conrad, a cognitive psychologist and Director of the Program in Survey Methodology at the University of Michigan Institute for Social Research (ISR).

“This is sort of surprising,” says Conrad, “since many people thought that texting woulddecrease the likelihood of disclosing sensitive information because it creates a persistent, visual record of questions and answers that others might see on your phone and in the cloud.”
