We want to throw science at everything to understand it better and make better things. After all, it’s how we got to where we are as a species. It’s also far more productive than burning or beheading people who say or discover truths we don’t like.
But when faced with the prospects of what science may find were it to study the potential dangers of the thing they like—guns, films, or video games—some science proponents respond with “no no, leave my thing alone, it’s perfectly fine. Go investigate that thing over there, that’s the problem.”
Truth is truth. We may not like what we find, but that doesn’t mean we should be afraid of investigating this thing but not that thing. Disagreeing with the results or fearing what change they might bring is not an excuse to silence science.
