Bright Idea Hat

Reduce meeting duration, increase productivity: Bright Idea Thinking Hat has a big lightbulb on the crown and when the wearer's brain activity reaches a creative peak the bulb lights up, just like the lightbulb over the heads of cartoon characters. During meetings anyone whose light is not lit is prohibited from speaking for more than ten seconds at a time. (Actually I suppose people could make their own rules to fit their organization.)

Of course the tiny sensors for detecting neurological activity in regions of the brain would need to be very sensitive, and people with Ted Koppel/Dolly Parton hair might have to wriggle the hat so the electrodes contact their scalps. But these problems are not insurmountable. Controls would fine-tune sensitivity to brain activity indicating various sorts of creativity--artistic, logical, social, amorous, etc. Imagine these hats in use during political debates--everyone could tell when a politician is really thinking and when he/she is just running his/her mouth!

Or is it too much like invasion of the mind?
