No worries: I wasn't angry or shouting. Sorry for coming too strongly. :) I understand what you are saying, but my point is that those two are in science a lot closer than you seem to suggest. Titles (such as a noble prize) are won thanks to reputation gained from those experiments and peer reviews. If your karma system is based on what you published and that is subjected to peer review and scientific methodology, then your reputation (i.e. your karma) are a good hint that the person knows what they are talking about. In other words: trust scientist --> high authority --> gained by good experiments and subjected to peer review
