Trust is the foundation of every area of life. Without it, it is difficult to
build lasting relationships. Unfortunately, in recent years, trust has been
severely damaged by the spread of fake news and disinformation, which has
become a serious social problem. In addition to trust, the factor influencing
interpersonal relationships is perceived attractiveness, which is currently
created to a large extent by digital media. Understanding the principles of
judging others can be helpful in fighting prejudice and rebuilding trust in
society. One way to learn about people's choices is to record their brain
activity as they make choices. The article presents an experiment in which the
faces of different people were presented, and the participants' task was to
assess how much they can trust a given person and how attractive they are.
During the study, the EEG signal was recorded, which was used to build models
of logistic regression classifiers. In addition, the most active areas of the
brain that participate in the assessment of trust and attractiveness of the
face were indicated.
