The word "debunk" is doing some heavy lifting in those articles. "....Overall 58 per cent of people actually disobeyed the pushy experimenter [which means that 42 percent didn't.] How can we understand this variability, Reicher asked, if the agentic state is true?"

Milgram found that 42% of people will administer electric shocks to someone who appears to be screaming in pain, as long as the order is given by an apparent authority figure. What is there to debunk, exactly?
Keep in mind what motivated these experiments: a desire to understand more about how the Nazis were able to accomplish what they did. It's not as if the findings of Milgram and Zimbardo were novel or controversial; they were merely trying to reproduce and understand something that the entire world had just observed.
