@lupyuen Some of the people commenting who were not involved in the experiment don't seem to appreciate how hard it is to make a decision to curb your use of a smartphone individually. It's not about personal responsibility when we are collectively coercing each other to have these things through network effects, expectations, and marketing. Also, it's difficult to use something safely that isn't designed with safety in mind and whose function and behavior can change with a software update. :/

@lupyuen We're discussing cell phone use in Toronto/Ontario classrooms now too! I'm not sure where I stand on this issue. Need to hear more from all the stakeholders.

@lupyuen They allow phones at school? Good idea
I once got smacked hard in front of the whole class by the PE teacher for sneaking in a dumb phone during the exam hour. No intention of cheating or anything, just my mother brainwashing the already innocent good boy me to carry one as a buffer for "emergency"
