Please read the post linked and think about the data we collect on students.
How can we make grading a more neutral act?
How do we convince others that they do not have the power or should not have the power?
How is the data I collect corrupting me?
How is the data our schools collect corrupting them, and in the process making them less valuable?
How do we be more open that all data collected has it base in subjective humanity?
Do we regularly look over the data we collect and try to find where it is giving us bogus information?
