A group of psychologists say scientists will never make contact with aliens because aliens are likely to use communications based on unknown physical principles. They also say scientists are prone to so-called inattentional blindness.
A group of psychologists from the University of Cadiz in Spain has published an article criticizing alien-seeking scientists involved in the Search for Extraterrestrial Intelligence (SETI) project, saying they will never make contact with extraterrestrial civilizations.
According to the article, published in Acta Astronautica, the scientists involved in SETI are concentrating solely on searching for radio signals when aliens are likely to use other forms of communication, including those based on undiscovered physical principles. Therefore, humanity will not be able to recognize those signals.
