Yeah, it seems like you'd basically always get good outcomes in a school like this.

If the students become disruptive instead of just wasting time on their phone it could have a negative impact in many schools.

Look at it the other way -- the fact that even such an elite school was having serious problems when they were allowing smartphones, shows how pernicious their influence is in education. It's like putting a TV with full access cable on every desk in the classroom. It's no wonder literacy is going down instead of up for the first time in decades.
