"We didn't think that he was lying to us. That was a mistake." It's scary how easy it is to socially engineer people and get what you want. While some of this comes from experience I feel that some people are just wired in a way that makes them easier to dupe independent of their education and intelligence.
People don't fact check what they want to hear and which supports existing narratives. The largest company in the world making their money on the backs of exploiting the very poorest is a common trope so it's one that doesn't get much fact checking. People aren't wired that way, it takes a good 12 years of teaching them to regurgitate 'quasi-facts' to get them out of their more curious fact checking nature. Every kid…
Except they did fact check those parts:
"In our original broadcast, we fact checked all the things that Daisey said about Apple's operations in China," says Glass, "and those parts of his story were true, except for the underage workers, who are rare. We reported that discrepancy in the original show. (...)"
What wasn't true was the stuff that the guy claim to had experienced personally.
