No smileys, please
Researchers from three universities, the University of Amsterdam, the University of Haifa and the Ben-Gurion University in Israel, have carried out research into how people perceive the smiley face emoji in official communications. They found that the emoji reflects badly on the sender.
“Our findings provide first-time evidence that, contrary to actual smiles, smileys do not increase perceptions of warmth and actually decrease perceptions of competence. Perceptions of low competence in turn undermine information sharing,” they said.
