Does a Montessori Education allow children to gain the traits of all birth orders?

Research shows that there are personality traits that tend to pertain to people based on their birth order. The traits most observed based on birth order include:

Oldest:

• Higher academic achievements and ambition
• Stronger sense of responsibility and maturity
•  Better leadership skills

Middles:

• Cooperative
• Flexible in a social setting
• Able to make and maintain friendships easily

Youngest:

• Charming and likeable
• Creative
• Strong sense of security and confidence

I have often wondered though if children who attend Montessori schools with three-year age groupings get the benefit of developing all of these traits. They are able to be the youngest, the middle, and finally the oldest in a social group setting that is similar in many ways to the home.

What do you think? Do Montessori children learn to be more well-rounded individuals with all of the above traits?
