Washing wisdom

Is it true that people behave the way we expect them to behave?

In the “Pygmalion Effect”, teachers who expect students to do better actually cause their students to do better.

Wiki says it’s more commonly known as the “expectancy effect” where students perform better than other students simply because they are expected to do so.

It’s conventional wisdom in the profession and has been for more than thirty years.

And it’s bunk.

The self-fulfilling prophesy might be junk science.
