I mean, this study was done in 1966. The IRB was established in 1974. I'm not saying we should celebrate this research, but ... we already learned the lesson about being careful with human experimentation? If there's a more recent study that circumvented the IRB or that the IRB okayed despite obvious problems, there's an interesting discussion to have there. But I'm more in the camp above, that this pre-IRB study wasn't particularly egregious, at least by the scale of atrocities of early 20th century research.
