What betrays the rejection of science even more, is making blanket statements or taking strong standpoints, especially on controversial topics. It betrays a propensity for scientists to ignore evidence, or to frame conclusions and experiments to fit their preconceived notions. I would include strong support of religious  viewpoints, athiesm and even global warming under this rule.<p>Once politics or agendas get involved, then science takes a back seat to convincing others that you are right.
