No, you can't change it. As soon as it is posted again, it is immediately flamed down as bogus. People don't apply equal weights to any source. If it comes from Henry Spencer or Mike Godwin it'll be closely examined. Through postings in moderated groups of known reliability, and references in other groups.
Similar moves are under study or development elsewhere in the U.S., Japan, and Europe.
I recommend the article to readers of this forum. It does a good job of exploring how people assess risks and probabilities with a number of examples. While there are many real risks in the world, I felt the Nova show emphasized risks rather than unlikelyhoods. Perhaps that was their intent. My problem is that I feel that people are acutely tuned to risks and not the unlikelyhood of many occurrences.
