You want to know how to drive a scientist crazy? Insist that you believe something that’s not supported by current scientific evidence. Tell her vaccines cause autism, or creationism is just as valid a theory as evolution, or that climate change isn’t really happening, I mean, after all, a monster blizzard hit Washington DC this January! Global warming, pssh…
There’s an old episode of Friends that did a good job of showing how this kind of conversation goes. Phoebe professes not to believe in evolution and Ross, a paleontologist, keeps trying to convince her that evolution is real using scientific evidence and logic. He grows increasingly frustrated and insistent as she continues to deny the basis of his life’s work, finally losing it when she goads him into admitting (like a good scientist) that even theories like evolution are not immune from questioning and testing.
We train scientists to carefully generate, weigh and use evidence. To no one’s surprise, this leads many scientists to generalize and think that in all matters having to do with the physical world we all should and of course will follow the evidence. Yes, sometimes that leads to unpopular ideas, and sometimes the ideas change as the weight of evidence changes. This training can make scientists kind of boring at cocktail parties. Still, the overall scientific process keeps moving forward and it’s because of this reliance on evidence.
But many people (including, at times, even some scientists) don’t always think the same way about things in the physical world. And that’s why I’m pessimistic that CRISPR-Cas technology will peacefully resolve the Genetically Modified Organism (GMO) debate. Continue reading
