Bruce Riedel, former CIA analyst, presented a dilemma to the audience during his 10:45 a.m. lecture Tuesday in the Amphitheater.
He asked the crowd to imagine being given pieces of a jigsaw puzzle. However, it can’t be certain whether the tasked puzzle has 500 pieces or 1,000 pieces. Either way, there are only 100 pieces at the moment. What’s worse: Not all of those pieces belong to that particular jigsaw puzzle, but it’s unknown which ones don’t belong.
