TIL I learned the difference between TED and TEDx.
TEDx events are independently organized TED-like conferences that operate under a free license granted by TED. While they follow the general principles of TED, TEDx events are planned and coordinated by volunteers at the local level, aiming to bring the TED experience to a broader audience.
For as long as I remember TEDx to exist, I hear people complain that ted talks suck now.
I always ask for example talks, and without fail it was a TEDx talk. And they never know that TEDx talks are very hit or miss in quality.
“proper” TED talks generally (but of course not always) have good quality (although, I haven’t watched any lately. But a couple years ago I watched basically any tech or science related one)
Even proper TED talks can have some big issues. I’m thinking specifically about Kary Mullis getting up on stage and saying anthropogenic climate change isn’t real because he found a study that says there’s a current that fluctuates and absorbs anything we do–or something to that effect. If you didn’t know anything about Kary Mullis and just heard “Nobel prize winner” you might assume he’s credible. In actuality he was a pariah for talking out his ass about things he doesn’t have expertise in and doesn’t understand, specifically his climate and HIV/AIDS denialism.
It’s always a good idea to approach any lecture with a critical view, but I can see why TED talks might warrant extra scrutiny. They project expertise and authority which may or may not actually be credible. The organization has a mottled record of vetting their speakers for actual expertise. (ETA: actual expertise in the content of their talk. Obviously Kary Mullis had actual expertise, just not in the things he said on stage)
For anyone curious, he figured out how to rapidly amplify samples of DNA. While doing that he would routinely cause trouble by doing things like bringing a gun to work and having public arguments with his girlfriend at work. His Wikipedia entry sounds as sane as he is.
