SF Gate columnist Mark Morford pointed me to this one:
The Edge Annual Question — 2008
“When thinking changes your mind, that’s philosophy.
When God changes your mind, that’s faith.
When facts change your mind, that’s science.WHAT HAVE YOU CHANGED YOUR MIND ABOUT? WHY?
Science is based on evidence. What happens when the data change? How have scientific findings or arguments changed your mind?”
165 “important” people answered the question, most of them scientists, but not all–Alan Alda is one of the respondants, for example. Mark Morford suggests reading the list (or a representative sampling)–and then answering the question yourself.
