Note: In For Your Own Good, Alice Miller herself credits Katharina Rutschky and her 1977 work Schwarze Pädagogik as the source of inspiration to consider the concept of poisonous pedagogy, which is considered as a translation of Rutschky's original term Schwarze Pädagogik (literally "black pedagogy").
