I'll also agree that funding can be a significant influence.<br /><br />During the 70's or so, a lot of studies on the sun were aimed at determining it's climate impact, and was marketed as the reason for the cold snap. It got hyped pretty bad, as is mars missions now. You have a lot of people heading in one direction, because it's where they can get funding.<br /><br />However, the answers are still valid, and there are enough people branching off in other directions that we still explore many options.<br /><br />I think this is the same thing going on in atmospheric sciences today. Everything is linked to global warming...sooner or later the entire truth will come out, and the field will shift to something else (or just get less funding, as the hype is gone).<br /><br />But anything other than a slight bias in results (which is nearly unavoidable, we are human) is really ripped to shreds in peer review system, and in subsequent citations. For instance, most laymen know that a scientist makes his name by publishing. What they don't know is that how often the work is cited also plays a large role. Publish a lot, but not get cited...doesn't do much for you. Publish a few times, but get monster citations (meaning you did something hard to do, and everybody thinks you did it right) on a few papers...and you're doing pretty well. <div class="Discussion_UserSignature"> <p align="center"><font color="#c0c0c0"><br /></font></p><p align="center"><font color="#999999"><em><font size="1">--------</font></em></font><font color="#999999"><em><font size="1">--------</font></em></font><font color="#999999"><em><font size="1">----</font></em></font><font color="#666699">SaiphMOD@gmail.com </font><font color="#999999"><em><font size="1">-------------------</font></em></font></p><p><font color="#999999"><em><font size="1">"This is my Timey Wimey Detector.
