The Surprisingly Simple Reason Teams Fail | Tessa West | TED

In 1999, a NASA mission to Mars failed … not from a technical glitch, but because people weren’t talking to each other. Psychology professor Tessa West explores how assumptions, overlooked details and “hidden languages” can quietly sabotage even the smartest teams — and explores the small shifts in communication that can make a big difference…

    That was one of the mostly poorly communicated TED talks ever – a combination of statements of the bleedin’ obvious and pure gibberish.

    Did anyone even bother to check the thumbnail spelling?

    A powerful reminder that failure often isn’t about intelligence or technology, but about how we communicate. This really stays with you.

    It is the Cool Hand Luke problem. “What we have here is a failure to communicate.”

    I’ve worked at a lot of different places. Every time to you go to another company you have to learn a foreign language. If you don’t have an acronym list it is hard to figure out the decoder ring. The military has training for something like this, but may not realize it. It is the Marine Corps 6th General order. 6. To receive, obey, and pass on to the sentry who relieves me, all orders from the Commanding Officer, Officer of the Day, Officers, and Non-Commissioned Officers of the guard only. It is call passing the word. Also, in Extreme Ownership they talk about effectively communicating and following up to make sure the word is passed.

    Sometimes communication is difficult because the company is always looking for the cheapest option. So the good people leave. And the people hired don’t speak the company’s language well (English, German etc…) and aren’t engaged. So it’s pointless to think we need to improve communication when we’re dealing with a problem of skills and social abilities, and a complete inability to progress

    The problem is finding a balance. Certain standards create a common vocabulary, which is good. Except that sometimes it’s so verbose that it becomes useless. And sometimes people who are very picky about words do so because they struggle with the work itself, so they comfortably remain at an easier level…

  21. @user-fk8zw5js2p

    February 2, 2026 at 8:20 am

    If you knew what was meant by, “How to Communicate Big Deicsions,” then communication was accomplished regardless of the spelling mistake and we all can move one.

    🤣

    One way to tell this was a good TED talk is because people trying to find something wrong with it can’t find anything wrong with what the speaker actually said.

    I believe it’s ‘teams’, not ‘Teams’. It’s not about the Microsoft product.

    Yes, the talk could be better. But the message is very important and recognizable

The Controversial Climate Tool Funding Real Change | Sandeep Roy Choudhury | TED

If a company plants trees to offset its pollution, is that climate progress — or is it greenwashing? Critics of carbon markets say it’s the latter. But Sandeep Roy Choudhury, who’s spent two decades financing climate projects from rural cookstoves to coastal forests, says the real failure is discouraging companies from even trying. Hear his…

If a company plants trees to offset its pollution, is that climate progress — or is it greenwashing? Critics of carbon markets say it’s the latter. But Sandeep Roy Choudhury, who’s spent two decades financing climate projects from rural cookstoves to coastal forests, says the real failure is discouraging companies from even trying. Hear his case for why we shouldn’t let perfection block meaningful action on climate change. (Recorded at TED Countdown Summit 2025 on June 17, 2025)
