DO TEACHERS SHOW MINORITY STUDENTS A “POSITIVE BIAS” THAT THWARTS ACHIEVEMENT?  A new report from the Journal of Educational Psychology confirms common sense:  Political correctness and an overzealous attempt to be “nice” or “gentle” with minority students undermines their success by failing to provide the kind of critical feedback needed for improvement. A fake, poorly written essay was submitted to teachers for feedback. The teachers “displayed a ‘positive feedback bias, providing more praise and less criticism if they thought the essay was written by a minority student than by a white student.”
