columnWhat did you oppose in the Stevens/Goldberg columns Kevin?   I was one of those that read Steven's more or less neutrally.    I have a problem with those who don't want to do anything before they have certainty in the results.   Science if full of constructive failures that move knowledge forward.  

My wife and her search dog  volunteer with the Sheriff's department.   While he may not find a lost subject in his assigned search area, he can cover a lot of ground and which helps define where the person isn't.    That's a significant step in any search.   

We are now in the search stage for solutions to an incredibly complex global challenge, I would expect more failures will follow, each contributing to our knowledge base and moving us closer to effective solutions.

By the way, I'm  glad you're writing on this site and enhancing the conversations.
