Smartphones called truth serum: people are ready to provide intimate information about themselves

Smartphones called truth serum

Researchers at the University of Pennsylvania studied the effects of smartphones on humans. The device with which people communicate can affect the degree of trust in each other. And scientists called this trust the “truth serum,” because it can contain very intimate or very personal information about yourself. Simply put, smartphones can increase consumer self-disclosure. The authors of the study are Shiri Melumad and Robert Meyer.

They concluded that users trust smartphones more than desktop computers. For example, tweets and reviews compiled on smartphones are more likely to be written taking into account the views of one person setting out their position on a particular topic. In such cases, the user reveals his negative emotions or discusses personal issues of his family.


And when a user views a private advertisement, he asks for personal information containing contact details also on a smartphone, and not on his desktop computer or laptop. The smartphone affects human behaviour and scientists were able to prove it. They explain that recording on a smartphone often underestimates the disclosure of confidential information for two reasons.

One is connected with the convenience of a smartphone, with its mobile qualities of an actual handheld computer. The second reason is related to emotional associations that users would like to support on their device. The peculiarity of a smartphone is that a person needs attention and concentration before writing a message or creating a post.

This is due to the small screen size, small font size, which distinguishes it from a desktop PC. It is this process of increased attention and concentration that is one of the factors due to which people become more prone to self-disclosure.


Over the past years, the social effect of using smartphones has been manifested: in public places, users seem to be obsessed with content, ceasing to notice the world around them. The second reason that the researchers explain is related to the feeling of comfort and security that a smartphone gives users. In human life, mobile devices began to perform many important functions.

Another additional feature is related to the storage of important secrets and secrets. The subsequent effect of this factor is manifested in the fact that subsequently, such people are more willing to share their problems or difficulties with people close to them.
