You’ve probably had millions of these in your lifetime, but maybe you haven’t had a chance to share your ideas with the world outside of your college professors, drinking buddies, and coworkers. Here’s your chance. Ideas posted on BigThink.com can take the form of a question or a statement. You can, of course, interpret that however you wish, but bear in mind that by submitting an idea, you’re entering it into the public sphere. Sure, some of your ideas will be greeted with hearty hurrahs, but others might be met with strident disagreement. But that’s the fun of it. Enough preaching to the choir, enough ideological isolationism. We want to pull you into a lively and challenging debate. So what ideas qualify? Anything goes, really. It can be something you read and thought was interesting, or something you might bring up in conversation or over dinner with friends. Or you can think of it this way: what do you know that you think others should, too?
