TED Talks are Ideas Worth Spreading. At least that’s their tag line. And it’s accurate.

TED Talks are recorded and online, and free. The idea is to watch them, and spread them. They’re given by highly thoughtful people, many of them established leaders in their fields, other new emerging intellects. As they say, riveting talks by remarkable people. Watch some, you’ll certainly feel smarter.

Here are a few I’ve watched lately and I deem worth spreading:

Jim Fallon on the neuroscience of psychopathic killers:

Eve Ensler, author of The Vagina Monologues, on security:

Bruce Schneier, on “security theater,” where what makes you feel safer may not actually be making you safer. So what will?
