I put ABA in wikipedia an scrolled to the critique section.
https://en.m.wikipedia.org/wiki/Applied_behavior_analysis
Not fun to read. Really not. I also looked for the cited study that reproduce these findings.
Apparently ABA has the chance to traumatise a person, induce exploitable behaviour and induce selftdestructive thoughtpatterns.
Despite that, apparetly some individuals profit from ABA.
Here is the link to the study cited in wikipedia: https://journals.sagepub.com/doi/10.1177/13623613221118216
