the only real way to progess is to conduct studies, report the results in peer reviewed journals and proceed to the next question. science is the rational, incremental pursuit of knowledge
the problems come in interpretting the results - journalists have a responsibility to fairly represent the studies conclusions - often they're taken out of context
unfortunately, the american public is getting more and more scientifically illiterate [not helped any by those who think creationism is a science], so more people can be misled. basic statistics should be a part of everyone's education, probably more important for most people than geometry or trig or calculus. critical thinkling is required if we're to havbe an informed populace
and it matters because can vote, serve on a jury, etc, no matter how ignorant [ie, lacking in facts, not stupid]
