Study: Teens Optimistic About Innovation Brian Bergstein, Associated Press BOSTON Teenagers have some seemingly high expectations about what technology might bring over the next decade, according to a new Massachusetts Institute of Technology study.

The LemelsonMIT program, which focuses on encouraging young people to pursue innovation, commissioned its "invention index" in November, interviewing SUI} teens and 1,030 adults nationwide. The margin of sampling error was plus or minus 4 percentage points for teens and 3 for adults.
