Looking Over Your Shoulder Isn’t Good for Your IQ
Looking Over Your Shoulder Isn’t Good for Your IQ
From the Marshall Memo #435
This “Stat Watch” item in Harvard Business Review reports a study conducted by Read Montague (Virginia Tech and University College London) on the impact of competition on IQ scores. When 70 adults took an online IQ test and were continuously shown how they were doing compared to peers, everyone’s performance declined and the bottom 20 performers plummeted by 17 points. Social sensitivity definitely affects performance, and the notion that IQ is a stable, predictive measure is highly questionable.

Mentors.net - a Professional Development Resource
Mentors.net was founded in 1995 as a professional development resource for school administrators leading new teacher induction programs. It soon evolved into a destination where both new and student teachers could reflect on their teaching experiences. Now, nearly thirty years later, Mentors.net has taken on a new direction—serving as a platform for beginning teachers, preservice educators, and
other professionals to share their insights and experiences from the early years of teaching, with a focus on integrating artificial intelligence. We invite you to contribute by sharing your experiences in the form of a journal article, story, reflection, or timely tips, especially on how you incorporate AI into your teaching
practice. Submissions may range from a 500-word personal reflection to a 2,000-word article with formal citations.
