The next time you’re on a date, you may want to take a glance at your date’s ringer finger and their index finger. If their ring finger extends the length of their index finger, you may be dating someone who is verbal aggressive, according to a new study.
A team of researchers lead by Allison Z. Shaw, assistant professor of communication at the University at Buffalo, has found that verbal aggression (e.g. name calling, ridicule, insults, racial epithets, threats, etc.) may have biological causes that can be identified by the length of a person’s ring finger (second digit or 2D) to the length of the index finger (fourth digit or 4D).
