Thats an excellent question  Why would scientists in other professions urge scientific standards in fields other than their own  Its simple  Scientists do specialize but the scientific method is applied to all branches of science  Urging people to apply scientific methods to all branches of science is part of the overall objective of the scientific community    Similarly if I were a journalist specializing in one beat Id nevertheless want to urge all wouldbe journalists to employ ethical standards of journalism in any other beat  There may be some disciplines where the public has a strong interest in the subject and a lot of ink appears on the subject including some doubtful ink  Scientists or journalists in unrelated fields would naturally feel the need to urge appropriate tools of science or journalism so as to avoid the kind of mistakes that have plagued human civilizations since the dawn of recorded history  Urging people to examine the evidence for or against some theory with a skeptical eye is simply sound advice regardless of the subject  The dissent is not against any theory  The dissent is against sloppy methods for establishing which theories are viable and how we can be so sure of what we claim to believe
