Researchers have declared imouto to be a key to happiness after finding that people who grew up with sisters were significantly more likely to be happy.
University of Ulster psychologists surveyed 571 people aged 17 to 25 in detail about their family life, and found a significant positive influence when a person had a sister, with such individuals tending to be happier.
The professor in charge of the study suggests sisters exert a cohesive effect on families, whilst brothers tend to be divisive:
“Sisters appear to encourage more open communication and cohesion in families.
However, brothers seemed to have the alternative effect.
Emotional expression is fundamental to good psychological health and having sisters promotes this in families.”
He suggests families full of unruly otouto may be in trouble:
“We may have to think carefully about the way we deal with families with lots of boys.”
