Scientists takin’ it to the streets;
Q: “Wadda’ we want?”
A: “Evidence based research!”
Q: 'When do we want it?"
A: “When its peer reviewed!”
Science is a long term, systematic, cumulative, cultural activity. Not all that we think is known is completely right and it never will be, but unlike many other human activities, science seeks truth and admits to errors when they’re uncovered. Over the long run progress is possible.
Further, even when the science is right, not all applications of science are wise. The nazi chemists were pretty good at developing poison gasses, for example. Really, really bad judgement in application though… though I guess recent events suggest there are still those in this world who seem to disagree.
And speaking of plastics, which we were recently… for all of human history people have dreamed of a material that was cheap, versatile, easily formed, didn’t rust, didn’t rot, won’t get water logged, would last almost forever. So now we have plastics. Great science. And what do we make with it? Sporks, pop bottles, fast food containers - disposable junk made from the least disposable product the world has ever known. It seems a reasonable person might want to question whether the “invisible hand” always moves us in the wisest of directions.
