What you are proposing is basically ignorance. Ignorance in general never makes things better. It is not the fault of data that insecure people are insecure, it’s the fact that the insecure person interprets the data in a way that reinforces the notion of themselves they hold. Even if we got rid of all numbers and comparison methods, insecure people would still feel insecure about themselves, they would just use a different metric, such as looks, or perceived mental abilities, or charisma, or whatever their minds feel is appropriate to compare and dismiss themselves with. There are far more effective ways to reduce insecurity, or extending further to school shootings, than by obscuring metrics. Such as by having a well run counseling program, an array of after school activities, discouragement of bullying, and simply better reporting on who the “troubled” students are so that they can be watched a bit more closely. Similarly, there are way more ways for a person to be alienated beyond just grades or other metric comparisons. We all know how high school was a popularity contest (at least it was in my experience), and none of that was fueled by grades or metrics, it’s all social skill development, testing the bounds of interactions, finding out what a friend exactly is, and all that other stuff they cover on Degrassi. As many say, the primary point of schooling is not to learn academics but to learn social skills and start figuring out how the world works. Well I also think the primary purpose of school is to relieve adults of the burden of their kids, allowing adults to pursue their career and secure stability for the family. In my mind, uncertainty is never good, let alone desirable in any way. Certainty and knowledge are valued over uncertainty and speculation, even if the knowledge isn’t what I want to hear. There will always be insecure and secure people in the world. I figure it’s a better approach to treat the underlying issues of why people are insecure rather than taking down one facet (data) insecure people use to judge themselves.
