In forgiveness-related studies conducted by the US-based Case Western Reserve University in Ohio, gender differences between men and women consistently emerged.

Forgiveness does not mean forgetting, condoning or excusing whatever happened. Its acknowledging hurt and then letting it go, along with the burden of anger and resentment.

An earlier research suggested that forgiveness may be good for ones health as holding a grudge appears to affect the cardiovascular and nervous systems.

Men have a harder time forgiving than women do, according psychologist Julie Juola Exline, who conducted the present study between 1998 and 2005 with more than 1,400 college students.

However, the gender gap closes, and men become less vengeful if males develop empathy toward an offender by seeing they may also be capable of similar actions.

“The gender difference is not anything that we predicted. We actually got aggravated, because we kept getting it over and over again in our studies,” said Exline.

She said previous studies have suggested that men tend to be more vengeful than women, who have been taught from childhood to put themselves “in the shoes of others” and empathize with them.

Women, having been taught from an early age to be more empathetic, lean toward relationship building and do not emphasize the vengeful side of justice to the degree that men do.
