  Text-based communication, such as text chat, is commonly employed in various
contexts, both professional and personal. However, it lacks the rich emotional
cues present in verbal and visual forms of communication, such as facial
expressions and tone of voice, making it more challenging to convey emotions
and increasing the likelihood of misunderstandings. In this study, we focused
on typefaces as emotional cues employed in text-based communication and
investigated the influence of font design on impression formation and
decision-making through two experiments. The results of the experiments
revealed the relationship between Japanese typeface design and impression
formation, and indicated that advice presented in a font evoking an impression
of high confidence was more likely to be accepted than advice presented in a
font evoking an impression of low confidence.
