JACK and Mia have been revealed as the 'naughtiest' names amongst children in the north west while children named Arthur and Isla are considered to be the most well behaved, according to new research.

Children, teachers and parents in the region agree that Jacks are the most likely to misbehave in the region, with over a quarter of those researched claiming children with the moniker are the naughtiest.

When it comes to girls, it’s Mias that teachers and parents associate most strongly with mischief, although girls’ names generally are considered to be less naughty than boys’ names.

The research, commissioned by My Nametags, also found boys named Harry are also considered to be shyest in the class, with their peers agreeing children with this name tend to be amongst the most introverted.

By contrast, boys named Leo are seen as the most confident children in the country, with none of the children surveyed considering them to be shy.

For girls, it’s Ellas who are assumed to be the most self-assured.

Why is this the case?

Chartered Clinical Psychologist and Scientist, Linda Blair, explains why these stereotypes exist: “In today’s information-rich world, we’re exposed to far more data than we can deal with at any given moment.

"To help sort through this avalanche, we form stereotypes about what people will be like based on only a few easily obtained facts such as facial expression, body posture and a person’s name.

“Rather than making judgments about others scientifically - taking a dispassionate look at everyone called Noah or Isabella, for example - we create our stereotypes using just the people we know, as well as those we think we know via social and other media.

“Once we’ve formed a stereotype, it becomes fixed in our minds because of a phenomenon known as ‘confirmatory bias’.

"This is when we look for and remember people who match up to the stereotype we’ve formed, while at the same time ignoring information that doesn’t fit. This is why we become so convinced our stereotypes are correct."

The study, which analysed the opinions of 1,500 teachers, children and parents in the UK, found that Brits are quick to make assumptions about a child based on their first name, with strong stereotypes associated with each of the names featured in this year’s top 20 baby names list.

The national results found that children named George are considered by both adults and their peers to be the most intelligent in class.

The name is also associated with kindness.

According to teachers, Isabella tops the list for girls when it comes to intelligence.
