has the top bit of Bloom blog gone all funny? And why can't I fix this myself?
It's because I have extremely poor self efficacy in this area. In other words, I expect myself to fail, so I do.
I mention this and I was reminded in the brilliant book Meaning Inc of Rosenthal & Lenore's experiment about children’s expectations. Simply by telling children and teachers that they were being watched as 'high performers' they raised performance by 0.6 of a standard deviation - enough to catapult an average performer to the top echelons.
Meaning Inc goes on to ask whether organisations' high performance programmes are worth the effort. They may get 25% more from the top 5%, but at what cost to the 95?
