There’s a lot of info out there about this case. What that boy went through was horrific and unethical. Children are not there to be experimental guinea pigs.
This quote from the Guardian about the case:
For Lynne Segal, the story of the experiment does not settle the nature/nurture debate one way or the other - her view, widely shared today, is that the dichotomy is false - but it shows the perils of psychologists trying to prove too much through research. "It's far too simplistic, and far too interventionist, this idea that we can control and model and shape people to prove one thing or another.”
